What is the methane gas detector's calibration principle?
The methane gas detector is a kind of instrument mainly used to measure the content of methane, which can continuously detect the concentration of methane in the working environment of flammable, explosive and combustible gas mixture, and is widely used in coal mine, petroleum, chemical industry and other industries. Because of its wide application, it is recognized as a necessary means of production by many companies. In the process of using the methane gas detector, the calibration principle is an aspect that we must pay great attention to. So do you know what the calibration principle of the methane gas detector is?
In principle, the calibration of the methane gas detector should use the standard gas that has been certified by measurement and matches the gas to be detected. First of all, before calibrating the methane gas detector, we should ensure that the surrounding environment of the combustible gas detector should be free of combustible gas. If there is combustible gas, remove the rain cover first, fill in a certain amount of clean air, and then continuously feed the sample gas to ensure the accuracy of the calibration.
When the measured gas is a hydrocarbon mixture, isobutane is the sample gas, followed by propane. For non-hydrocarbon mixtures or hydrocarbon mixtures with large differences in heat generated during combustion of gases with lower explosive concentration, as a last resort, easy-to-obtain and stable single-component fuels such as butane, isobutane, and propane can be used as samples. gas. At this time, the range of the alarm must be adjusted according to a certain detection signal conversion relationship. This also determines that the methane gas detector is a necessary material for enterprise production.
Secondly, this methane gas detector is widely used in environments or mines that contain methane or coal dust explosion hazards. Staff use it to measure methane content, and the operation is simple and convenient. When the methane gas detector detects that the methane concentration reaches the critical point in the industrial environment, it will send out an alarm signal to ensure safe production, property safety, and staff safety. It can be seen that the methane gas detector is a necessary production material for enterprises , Relevant companies should prepare one to prevent danger.
