Fixed Carbon Dioxide (CO2) Gas Detector Dimension (Unit: mm)
SISCO Gas Detector Catalogue.pdfQ1: 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: How to troubleshoot a gas detector?
- Values are not displayed correctly
If the gas detector has been used for a long time, or has not been calibrated for a long time, the problem of incorrect readings will occur. We all know that gas detectors are mainly detected by internal sensors. Sensors have a certain lifespan. When used for a certain number of times, the sensitivity of the sensor decreases, which affects the detection result. In addition, if the calibration is not performed for a long time, the test results will also be affected. - Gas detectors do not inhale
This type of problem mainly occurs with pumped gas detectors. There is a small getter pump inside the detector for sucking in gas for detection. Once the suction pump is damaged or otherwise faulty, the gas detector will not be able to suction. This problem is easy to deal with and can be replaced with a new oil well pump. - Gas detector failure
This kind of failure is easy to occur in special working environments, such as the presence of a large amount of dust and oil in the detection environment, which will contaminate the gas detector and cause failure. In such an environment, the gas detector needs to be cleaned.
