Common problems in the installation and use of gas detectors

Gas detector is a safety instrument tool used to detect the leakage of combustible / toxic and harmful gases. The gas detector can work normally, which needs to be installed correctly, and pay attention to correct maintenance during use. Today, let's talk about some common problems in the installation and use of gas detectors.
 
1. What is the farthest distance between the probe and the host?
The longest effective distance is about 1000m
 
2. What wire is used to connect the probe and the host?
Rvvp3 * 0.75 of branch line; Rvvp4 * 1 of bus
 
3. What are the output signals of the probe?
4-20mA current signal of branch line, digital analog signal and 485 signal of bus
 
4. Does the probe require power?
If necessary, the host provides 24V power supply for the detector. At present, the probe can also directly supply 220V municipal power.
 
5. Can the probe be connected with solenoid valve, exhaust fan, etc?
It can be connected. If there are special needs, it can communicate with the manufacturer separately.
 
6. What are the principles of probe detection?
Combustible: catalytic combustion, toxic: electrochemical carbon dioxide: Infrared
 
7. Where can the probe be installed?
Can do wall mounted installation, pipe holding installation, etc.
 
8. What is the effective radius that the gas detector can detect?
Effective radius of combustible gas detector: 7.5m. Effective radius of toxic gas detector: 1.5-2m
