Dew Point Meter

Hygrometers and Humidity Measurement Instruments Information

Hygrometers and humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air. The range humidity measurement instruments operate in is typically from 0 to 100% humidity. They are sometimes combined with other sensing devices such as temperature sensors.

Measurement Capabilities

Humidity measurement instruments and hygrometers can sense a number of different factors.

Absolute humidity, expressed as grams of water vapor per cubic meter volume of air, is a measure of the actual amount of water vapor or moisture in the air, regardless of the air's temperature.

Relative humidity (RH), expressed as a percent, also measures water vapor, but relative to the temperature of the air.

The dew point temperature, which provides a measure of the actual amount of water vapor in the air, is the temperature to which the air must be cooled in order for that air to be saturated and dew to form.

Because of the intertwining of atmospheric measurements, humidity measurement instruments are sometimes equipped with pressure and temperature sensors as well. Three main applications for humidity measurement instruments are judging moisture in gases or air, bulk solids or powders, or else if fuels or other liquids.

Technology

There are many technologies for humidity measurement instruments.

·  Capacitive or dielectric instruments have a material that absorbs moisture, which changes its dielectric properties and enhances its capacitance.

·  Chilled mirror technology uses a mirror that is chilled to the point that moisture starts to condense on it. This temperature is the dew point.

·  With electrolytic technology, moisture is proportional to the current needed to electrolyze it from a desiccant.

·  For resistivity or impedance style sensors, a material absorbs moisture, which changes its resistivity or impedance.

·  In strain gage instruments, a material absorbs water, expands and is measured with a strain gage.

·  Psychrometers, often called wet/dry bulbs, measure relative humidity by gauging the temperature difference between two thermometers, one wet and one dry.Range

One critical specification for these devices is the humidity or moisture range to be measured or else the dew point range. Humidity and moisture accuracy is expressed in terms of percentage of measurement. The dew point accuracy, since this is a temperature reading, is expressed as a variance in temperature output.

Output

Outputs from hygrometers can be:

·  Analog current

·  Voltage

·  Frequency

·  Digital, including computer signals

·  Switch or alarm

They can have analog, digital or video type displays and can have a number of different form factors. They can be PCB-mount devices, standard sensors or transducers, or a simple gauge or indicator. They can also be various types of instruments, whether handheld, benchtop or mounted.

Features

Humidity measurement instruments can have a number of features to make them more useful or easier to use. These can include:

·  Pressure and temperature compensation

·  Data logging

·  Event triggering

·  Self-testing

·  Self-calibration

·  Battery power

Portable Dew Point Meter :

Using Purpose Mainly The National Weather Service characterizes dew point as the temperature to which air should be cooled to arrive at immersion, expecting pneumatic stress and dampness content are steady. So, the dew point is an exact estimation of the dampness content noticeable all around.

Dew Point Principle

By Cooling at consistent tension if the temperature of the air is decreased, the water fume noticeable all around will begin to gather at a specific temperature. This temperature is called dew point temperature.

Depiction

The Main Parts of the course of action are A glossy surface (reflect) is fixed with a thermocouple. A spout is giving a stream of air to the mirror. A light source zeroed in continually on the mirror. A photocell to recognize the measure of light reflected from the mirror. The activity of Dew Point Meter The mirror is continually cooled by a cooling medium. The cooling medium is kept up at a steady temperature. To this mirror is joined a thermocouple whose leads are associated with a millivoltmeter. Continually a light is made to fall in a point on the mirror and the measure of mirrored light is detected by a photograph cell. Presently an air stream is made to fall in a point on the mirror and the water-fume (dampness) contained noticeable all around begins consolidating on the mirror and they show up as little drops (dew) on the mirror. This dampness (dews) framed on the mirror lessens the measure of light reflected from the mirror and it is recognized by photocell. When interestingly, there is an adjustment of measure of sent light; it turns into a sign of dew arrangement. In this case (that is, the point at which the due development is recognized first), the temperature demonstrated by the thermocouple connected to the mirror turns into the dew point temperature. Along these lines, this plan is utilized to decide the time at which the dew shows up interestingly and dew point temperature.

Gas Detector

Vasthi gas detector is a device that detects the presence of any gas within an area, usually as part of a safety system. This type of detector equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down. the detector can also sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave the area. A single gas detector device is important owing to the fact that there are many gases that can be harmful to organic life, such as humans or animals.
