How to Choose a Magnetic Speed Sensor Manufacturer

Sometimes choosing a manufacturer in any context can be difficult. When you’re searching the market, you’re bound to find many different manufacturers that could potentially suit your needs. This is also true when you’re looking for a magnetic speed sensor manufacturer. How do you know which company to go with? If you’re not sure, here are a few tips that could help you decide.

Design, Test and Assemble When you need a sensor built, sometimes it’s important that everything happens in one place. Not only is it more convenient, but there is less room for error if the sensor is designed, tested and assembled on site. If you’re looking for a good manufacturer, this is something that could set one above the rest.

Experience in the Industry Like most industries, you want to make sure that you go to a manufacturer with experience. Take Sensor Solutions, for instance, they have been in business since the 1990’s. With a company like that, you can rest assured that they have the experience and knowledge to assemble the magnetic speed sensor that you need. Not only that, but you can be sure that it’s going to work.

Ability to Design Custom Sensors If you need a custom magnetic speed sensor, it can be difficult to find a manufacturer that can create precisely what you want. However, it’s imperative that you find one that can. Not to mention, if you have a sensor that isn’t made anymore, it can help to have a manufacturer that knows how to custom build one. This keeps you from looking tirelessly for something that doesn’t already exist.

When it comes down to it, there’s nothing more important than making sure that what you purchase from a manufacturer is high quality and works well. These tips should make it easier to find a professional and quality service that can design the magnetic speed sensor that you need specifically.

How Gear Tooth Sensors Detect Minor Problems Before They Become Major

Many types of mechanical systems are complex and can present problems when the time comes to diagnose problems. One tool that simplifies the detection of minor problems, making it possible to avoid major problems, comes in the form of gear tooth sensors, such as the ones that can be purchased from Sensor Solutions. Transmission systems, in particular, might require consistent monitoring for protection from many common repair and replacement issues, as well as to save you from losses due to downtime. Some of the transmission systems commonly affected by problems that might be prevented through the use of these sensors are those found in wind turbines and some types of aircraft. 

In many industries, and particularly those that rely on accurate measurements of speed and position, the ability to create an electrical pulse, or current, with a gear system is a requirement. These mechanical systems are only as reliable and accurate as the quality of the contact between gear teeth. When the alignment of the teeth is off even by a tiny amount, efficiency can drop and uneven wear can lead to minor problems.

One preventative measure taken by professionals in related industries is the use of gear tooth sensors to measure the position of air gaps. Gear tooth sensing using the Hall effect (a magnetic technique of measurement) to sense any changes in the flux between the magnet sensor and the gear teeth.

In order to accurately sense the position of the gear teeth with the Hall effect, it is necessary to have a reliable source of magnetic energy. Many engineers achieve this by designing mechanical systems with permanent magnet sensors that work with the surface of gear teeth. By adding permanent gear tooth sensors to the system, minor problems can be identified quickly and any appropriate repairs or replacements can be completed. This is highly preferable to randomly running diagnostics and hoping to catch those small problems before it is too late.

Install Magnetic Sensors for High Accuracy

If you rely on sensors to measure the function of machinery, you know that accuracy is the most important feature a sensor can have. You probably test, calibrate and inspect your sensors consistently to ensure they are giving you accurate readings. If one were to be the slightest bit off, you could hazard a disruption in workflow, and that gets very expensive very quickly. That is why sensors are so important, and that is why magnetic speed sensors are so popular. These units are typically small, cylindrical and reliable in a variety of different machinery settings.

Magnetic speed sensors are also built to be resistant to shocks and vibrations. Because of their small size, they are easily placed adjacent to their target, but this also means that they may be jostled around. A high quality unit will be able to absorb the movement and maintain accurate detection of its target’s movement. As the ferrous point moves past the sensor, it will register the movement and rotation. This versatility makes them ideal for use in many different areas, and it also means they tend to be highly accurate sensors. Few other types of units are as adaptable as these.

When you are looking for sensors, keep in mind the environment you will be placing them in. Some materials are more resistant to oil, moisture and corrosion. Others are designed to absorb shocks more easily. There are a variety of makes and models, so it may be overwhelming to try and find the right one. Try to find a unit that meets your criteria and is made by a trusted manufacturer. Installing sensors is a big investment, so you want to be sure that the product you choose is reliable, well-made and durable. You cannot afford the setback a faulty sensor could cause, so invest in magnetic speed sensors that are trustworthy.

A Tool Powerhouse: The Hall Effect Sensor

A Hall effect sensor is a tool that measures magnetism. The science behind this multifaceted tool was discovered in 1879 by the American physicist Edwin H. Hall. He identified the Hall Effect: generating a measurable voltage by using a magnetic field. A magnetic field has two important features: flux density and polarity. The output signal from this type of sensor is the function of magnetic field substantiality surrounding the device. When the magnetic flux density around the sensor goes over a certain pre-set threshold, the sensor notices it and produces an output voltage called the Hall Voltage.

There are two main kinds of these sensors: linear and threshold. In the linear Hall effect sensor, the voltage output depends on the magnetic flux density in a linear way. In comparison, the threshold type has a sharp decrease of output voltage at every magnetic flux density. In most cases, these sensors and switches are designed to be in the OFF mode (open circuit condition) when there is no magnetic field accounted for. They only turn ON (closed circuit condition) when they come into contact with a magnetic field of adequate strength and polarity.

A Hall effect sensor is a basic, cheap, electronic chip that has applications in all sorts of widely available products and gadgets. One way they work is to detect something’s position. For example, you could put a Hall sensor on a doorframe and a magnet on the door itself, so the tool would determine whether the door is open or closed from the activity of the magnetic field. You might say you could do the same job with a magnetic reed switch, but what you can’t do with that is determine the strength of the magnetism, because a reed switch is either on or off. They are also used in automotive fuel level indicators to identify how much fuel is in the tank. Detecting ferromagnetic materials, or materials that have a high susceptibility to magnetization, such as steel and iron, is yet another way to use these sensors.

The Science Behind the Hall Effect

Edwin Hall discovered the Hall effect in 1879, but at that point in history, it didn't prove to be of much use since scientists did not even know about electrons yet. However, it resurfaced the following century when people began learning about conductors and the physical makeup of currents. Today, it’s the foundation behind the analog hall effect sensor and other precision tools that measure magnetic currents. These devices can be used to detect speed and position for engines, computers, machinery, and more.

All electronic currents consist of charge carriers known as electrons, and when paired with magnetism, electricity can actually move things. This is the science behind gadgets like electric motors, headphones, and speaker systems. When using a semiconductor material, electrons move through it in a straight line, even while colliding with other particles within the current.

However, when you put that material in the path of a magnetic field that is perpendicular to the current’s flow, the electrons will deviate from that straight line. This is known as the Lorentz force.

The Hall effect is a measurement of the voltage difference created by the Lorentz force, and an analog hall effect sensor is designed to measure this difference with precise accuracy. As an electronic current interacts with the magnetic field, the electrons start to curve in between their collisions and accumulate on one side of the semiconductor material. When more electrons are present on one side than the other, it creates the difference in voltage, which is often referred to as Hall voltage. Stronger magnetic fields will deflect more electrons. Likewise, strong electric currents contain more electrons to deflect. Hall voltage represents the size of the imbalance that is created within the semiconductor.

The analog hall effect sensor and other probes that incorporate this technology can be used in a wide variety of industries. These devices detect precise measurements for underwater cable feeds, tamper-resistant gadgets, gas meters, motion sensors, and hundreds of other unique applications. Sensor Solutions has a complete line of Hall Effect Sensors.  Please visit www.sensorso.com for more information.

Design Considerations for a Magnetic Speed Sensor

A magnetic speed sensor is an important component in many high-performance measurement systems. These sensors generally use Hall Effect technology to create a high-speed output signal. Designers must consider several parameters in order to create a robust system.

Mounting

The designer must properly mount the target. One arrangement uses sensors placed to register gear teeth as they pass by. A measurement gear can be attached to the target armature. The number of teeth is the number of pulses generated by the sensor per gear rotation.

For a stronger sensor-target link, designers may choose a magnetic target. Tiny magnets generate a greater Hall Effect trigger, allowing the sensor to work in noisier environments, or at a greater distance. Magnets must be bonded to the target armature in some fashion. In some designs, the armature is pitted to allow a mounting spot for a magnet. Manufacturers also supply a magnet ring for attachment to an armature.

The magnetic speed sensor must be mounted to the fixed sensing housing and aligned to the target magnet. Depending on the sensing strength, the sensor is place at a distance of some tens of mils from the target. Designers can use the manufacturer’s design charts to choose the proper size sensor and sensing distance required. In addition, sensors can be sealed in order to endure harsh environments with little effect on the sensing action.

Sensor Interface

Standard sensor interfaces include NPN, PNP, or current sink (in the standard range of 4 – 20 mA), in order to interface with most control circuitry. Designers can create a digital interface by connecting the signal to a counter that is latched and reset on each sampling period. They can also create an analog interface by buffering the signal and integrating the output with a simple capacitor or other arrangement.

Sensor Solutions offers a wide range of sensors to suit a variety of applications. Their excellent applications notes will guide designers through the proper steps in choosing the right magnetic speed sensor at www.sensorso.com for the application, and in choosing the parameters.

This Is How A Magnetic Switch Works

  A magnetic switch is a simple tool used to control one simple function. This may be as simple as the closing and opening of two contacts. It may involve simply turning a circuit on, turning it off, or toggling between turning the circuit both on and off. The difference between this switch and other switches is that magnets are used to power it, rather than other means.

  There are a few crucial parts involved in the construction of a magnetic switch. These are an arm constructed of metal, two contacts positioned near the end of the arm, and a magnet that can be moved from one position to another. Some of these switches might also involve the use of a pair of magnetic clamps.

  When the re-positional magnets come near the end of the arm, the attraction between the conductive metal and the magnet will pull the two together. When the arm of the switch comes into contact with the magnet, the switch activates. Likewise, when the arm and the magnet move away from each other, the switch is again triggered. If there are magnetic clamps involved, the arm will remain where it is until the magnet moves again.

  There are a few different types of the magnetic switch available through quality vendors like Sensor Solutions. Depending upon what you hope to achieve, one or the other may be more appropriate. There are two basic types of switches; these are the monostable switch and the bistable switch. Of the monostable switch, there are two types. These include the open monostable switch and the closed monostable switch. Bistable switches will move from an open position to a closed position as the magnet moves. However, these switches will often stay in the second position after the magnet moves away.

  Magnetic switches have been around since the 1930s and offer many important benefits, such as a low rate of contact resistance, a good switching speed, and a healthy lifespan. These switches are sealed and so they aren’t prone to the sparking hazards that other switches might create under some circumstances.

  When your task requires the use of a magnetic switch from Sensor Solutions, make sure that you understand the type of switch you need and how that switch will be best used.

What Are Gear Tooth Sensors And What Do They Do?

A gear tooth sensor is used to measure speed and is sold by Sensor Solutions. This type of sensor is used to measure rotational velocity, or the speed of an object as it spins around. Rotational velocity has more applications than might be apparent; even vehicles that move in straight lines like cars can have their speed determined by measuring the rotational velocity of the axles.

A gear tooth sensor uses the Hall Effect. The Hall Effect is the tendency of a piece of metal to become electromagnetically charged when in the presence of a magnet. A sensor using the Hall Effect consists of a rotating gear, a magnet, and a magnetic sensor. When the gear’s teeth rotate past the magnet, the sensor reads the changes in the magnetic field to determine how quickly the gear is rotating.

There are many different applications for a magnetic gear tooth sensor. Since they measure mainly speed, they can be used in any situation where you want to know the velocity of an object. One of the most widespread uses of speed sensors is for the speedometers in trucks, cars, trains, bicycles, or other vehicles. Gear tooth speed sensors help the driver or operator to determine how fast they are traveling, and thus whether they are moving at a legal and safe speed.

A gear tooth velocity sensor can also be used in industry for other types of non-traveling machinery. For example, some factory equipment might have a velocity sensor attached to the rotating or moving parts to show the speed at which the equipment is working. If the speed is too low, that might indicate damage or another problem, but if it’s too high the machine might overheat. Speed sensors are used to ensure that the equipment is operated safely.

There are many uses for a gear tooth sensor from Sensor Solutions; the only limit is your engineering ability and imagination. They can measure speed and rotational velocity quickly and accurately; it’s no wonder that they have become so widespread.

How an Analog Hall Effect Sensor Works

Hall effect devices are used in a variety of electrical applications, from computers to sewing machines, automotive to aircraft, basic machinery to medical equipment. These sensors are often called “switches,” as they are used to trigger circuits within an engine or other electricity-based device. They can be used for positioning, detecting speed and proximity switching, among other things. An analog Hall effect sensor can be to generate a continuous voltage output, whereas digital devices are either turned on or off.

The Hall effect uses elements made from a thin sheet of conductive materials that have output connections that lie perpendicular to the direction of the flow of current. When a magnetic field is introduced, the sensor outputs a voltage proportional to the magnetic field strength. Typically, this is a very low level of voltage, and additional electronics are required to make the voltage useful. Therefore, when adding other devices to the element, a digital or analog Hall effect sensor is formed.

In layman’s terms, when a metal blade passes through a magnetic field and a silicon chip, the blade blocks the field and causes the chip’s output to drop to zero. Conversely, by adding more circuitry, the sensor can cause the chip to output higher voltage. In a practical application, like in a car’s ignition system, a digital Hall effect device is used to produce a signal as the crankshaft rotates. A digital sensor can operate in “on” and “off” modes, as an analog sensor provides a continuous, varied voltage output depending on the magnetic field.

The advantages of using Hall effect devices include that they have a long life doing highly repeatable operations. They also operate at high speeds, meaning they can generate their output quickly. They generally do not have any moving parts, which means they are lower maintenance. They are able to withstand a broad range of temperatures, from well below freezing to well over boiling point. The application’s need for either continuous or on/off output will determine whether or not to use a digital or analog Hall effect sensor.

The Most Typical And Unusual Applications For Proximity Sensors

Proximity sensors are one type of technology that is frequently used in everyday life. Many people are familiar with this technology and can probably name a few uses for it, but most people would be surprised to know how often they come across these sensors while going about a routine day. Here are a few of the most common - and the more unusual - things that make use of a proximity sensor.

The everyday uses.

As you might guess, there are many of these. Many new cars use technology to detect proximity of other objects and help prevent drivers from backing into something, running over someone, drifting into an accident, or bumping another vehicle while parking. Smart phones often use proximity sensors so that, when you answer a call or listen to something and bring the phone to your ear, the screen will lock, preventing you from hitting random buttons. Proximity sensors can also open automatic doors or trigger lights. In the same sense, these sensors can also be used to monitor occupancy in a room or building, determining lighting and energy use. Finally, many machines also make use of these sensors to make sure that everything is moving at the correct speed and that nothing has broken.

Less common uses.

There are many interesting and specialized uses for proximity sensors. These sensors are essential in aviation, as they can alert pilots if they are close to hitting the ground or flying into an obstacle during low-visibility conditions. Proximity sensors can also be used in the opposite case, to detect aircraft from the ground in anti-aircraft technology. These sensors also have some unexpected uses - for instance, in the trim brakes on roller coasters, which are brakes on the track that slow the coaster down to an acceptable speed; the sensor measures the speed so the appropriate braking force can be applied.

There are many other ways that proximity sensors can be used, depending on the nature of the sensor. If you need a proximity sensor, you can visit the Sensor Solutions website to see if they have your questions answered and to check out their line of magnetic proximity sensors, Hall effect proximity sensors, and ferrous metal proximity sensors.
