FAQs

Q1: What is a fixed gas detector?
A1:
The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.

Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.

Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.

Tips: What are the installation requirements for fixed gas detectors?

The fixed gas detector is generally fixed on the wall, but different heights will affect the accuracy of the gas detector, which is a major focus of installing it.

  • The density of the gas to be measured
    When installing a fixed gas detector, you should first consider the density of the gas to be measured. We all know that the density of various gases is different from the density of air. If the density of the gas to be tested is greater than that of air, it should be installed below the gas released; if it is less than air, it should be installed above the leakage of the gas to be tested, so that the gas can be detected faster and more accurately.
  • Annual inspection
    To ensure its detection accuracy, gas detectors should be calibrated at least once a year.
  • Distance between controller and fixed gas detector
    The controller and the fixed gas detector cannot be placed together. The gas detector is installed in a dangerous area where gas is easy to leak and accumulate, while the controller is installed in a safe area that is easy to see.
