1. Gas detector detects the specific gravity of gas and air
Since the detected gas is heavier than air, it is necessary to put thegas detectorInstalled close to the ground, usually about 30cm from the ground, in order to detect gas concentration quickly, accurately and stably, and take corresponding safety treatment measures.
To detect gases lighter than air, it is necessary to install them near the ceilinggas detector, usually about 30 cm from the top. It should be noted that the standard installation position of the gas detection alarm controller host is 160cm from the ground, which is convenient for operators to operate and avoid the instrument itself becoming an obstacle.
2、 gas detectorProbe wiring
The Gas Detector probe wiring is very simple, as long as you know how many probes should be installed in the probing environment, and then choose a three-wire or four-wire system depending on the number of probes. In order to increase the number of probes in the future, it is recommended to adopt a four-wire system to facilitate the subsequent addition of probes and maintenance.
After determining the use of four-wire output, it should be based on thegas detectorThe number of probes and the position of the gas to be measured should be set up with reasonable wiring. This one is very simple, just need to connect in series, and use the junction box to hold the probes one after another.
3、 fixedgas detectorand debugging
After selecting the position of the gas detector probe and the direction of the line, the rest is the actual work, just fix the gas detector probe and line power cable. After inspection, power on test. Due to the complexity of the debugging process of the gas detector, the gas detector has been debugged before leaving the factory, and the user does not need to perform any debugging operations.
