Combustible gas alarm is the 1 kind of gas detection equipment installed in explosive dangerous environment, which has a positive impact on the safety of industrial environment. Therefore, to ensure the normal operation of combustible gas detection alarm, it is necessary to calibrate the probe regularly on time, so as to better ensure safety. So do you know the calibration steps for the Combustible Gas Alarm probe? The following is a brief introduction by yi yun Tian:

combustible gas alarm probe calibration steps:

1, zero adjustment

After the power is turned on, combustible gas alarm probe in fresh air (or nitrogen) run for 30 minutes, adjust the circuit board" zero potentiometer ", so that the secondary instrument display value is zero.

2. Range calibration

3. Measured gas

is a mixture of hydrocarbons, isobutane is the sample gas, followed by propane. For non-hydrocarbon mixtures or gases with lower explosive limit concentrations, the heat generated during combustion differs considerably.

In summary, this is the calibration procedure for the combustible gas alarm probe.Combustible gas alarm is the 1 preventive alarm in regional safety monitor. After installation, once the concentration of combustible gas in industrial environment reaches the critical point of lower or upper explosion limit, combustible gas alarm will send out alarm signal to remind staff to take safety measures, and drive exhaust, cut-off and spray systems to prevent explosion, fire and poisoning accidents, so as to ensure safe production.
