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: of Fixed gas detectors common faults
- If the fixed gas detector won't turn on, the voltage is too low. The solution is to plug in the power supply or charge it in time.
- The inaccurate indication value of the fixed gas detector is caused by the long-term non-calibration of the detector and the overtime of the sensor. The solution is to replace the sensor.
- When there is no gas that can be detected, the fixed gas detector interface displays a value, which is caused by sensor drift, so it is necessary to perform zero calibration in time.
- If the normal detection interface of the fixed gas detector displays the full scale, it is a sensor failure. Replace the sensor in time.
- If the sensor of the fixed gas detector drifts too much and the zero calibration function is unavailable, the sensor should be calibrated or replaced in time.
- Fixed gas detectors do not respond to detected gas. Possible causes are circuit failure or sensor end of life. The solution is timely maintenance.
