Tracer Gas Detection

Gas detectors are safety instruments that are predominantly used for safety purposes. They have inbuilt sensors that are designed and manufactured to detect one specific gas or multiple gases. So it can be concluded that the sensors in the gas detectors play a major role in it. They are the ones that are responsible for detecting the presence of certain gas and alert the people. In terms of technology the gas detectors can be majorly classified into two types. They are based on the type of gas they are capable of detecting. The first one is the toxic gas detectors and the other one combustible gas detectors. As the name states the sensors in the toxic gas detectors are designed to detect toxic gases and the sensors in the combustible gas detectors are designed to detect combustible gases.  The technologies involved in programming these sensors are very complex. We will see in detail about tracer gas detection. When using tracer gas leak detection to track the movement of material through an industrial system, leak measurement methods can be either static, in which tracer gas accumulates in a sealed chamber, or dynamic, in which the tracer gas chamber is pumped continuously in order to move gas through the leak detector. But complex detection mechanisms are not always necessary, as leak detectors can range from sophisticated mass spectrometer devices to simpler instruments and even human senses, such as sight and smell.

Gas Detection Terminology

Gas detector is an appliance that detects the presence of certain gases with specific technologies. They are generally battery operated devices that are installed for safety purposes majorly to prevent toxic gas exposure and to avoid fire explosions. The alerting process is either alarms or through lights. There can be instances where it can be a combination of both. The conventional gas detectors were manufactured to detect one specific gas. On the contrary modern gas detectors are designed and manufactured to detect various gases. The modern gas detectors can be used as single entities or as a combined entities to linked together to provide protection.  Here we will see in detail about the terminologies in gas detection. In order to understand the principles of leak detection methods, it is necessary become familiar with the terms used in the process. A leak itself is defined as the passage through which a gas or fluid escapes, leakage refers to the fluid escaping, and leak rate is the amount of fluid or gas passing through the leak over a unit of time and under a specific set of conditions. The minimum detectable leak is the smallest passage or flaw that can be detected in a leaking system, while the minimum detectable leak rate is the lowest rate of escape that can be identified and measured. Minimum detection levels are used to determine the sensitivity of a leak detector, but these values are often influenced by variables such as operating pressure and temperature.
