Nowadays, with the deepening of people's awareness of security, the installation of combustible gas alarm has been popularized by people. However, in the process of long-term use of combustible gas alarm, sometimes due to various reasons or improper operation, sometimes there will be continuous false alarm of combustible gas alarm. So what should be done when combustible gas alarm has a continuous false alarm? The following is a brief introduction by yi yun Tian:

causes and treatment measures:

1. Probe or alarm aging

Treatment measures: re-calibrate, replace probe or replace combustible gas alarm.

2. Interfering gas in the detection environment

measures: taking the sulfur dioxide detector based on electrochemical principle as an example, it is mainly used to detect the concentration of sulfur dioxide gas, but it will react to carbon monoxide, nitrogen dioxide, ozone and other gases. If the concentration of carbon monoxide, nitrogen dioxide, ozone and other interfering gases in the detection environment is too high, the accuracy of ozone gas concentration will be affected, resulting in excessive error of combustible gas alarm value. Combined with this complicated situation, when we dock with customers on site, the type of interference gas that may exist on site will be confirmed, and then the filtering algorithm of interference gas will be added pertinently. The combustible gas alarm has an interference compensation algorithm, which can reduce the influence of interference gas on the target gas detection.

3. High-power devices running intermittently in the detection environment

treatment measures: when the combustible gas alarm around the inevitable use of high-power equipment, such as generators, wireless transceivers, compressors, mobile walkie-talkies, etc., will affect the detection of combustible gas alarm, usually the performance of the reading mutation and then false alarm.

To sum up, it is the possible causes and treatment measures of continuous false alarm of combustible gas alarm.Combustible gas alarm is the 1 kind of gas leakage detection and alarm instrument. When combustible gas leakage occurs in the industrial environment, when the combustible gas alarm detects that the gas concentration reaches the critical point of explosion or the alarm setting, it will send out an alarm signal to remind the staff to take safety measures and drive the exhaust, cut-off and spray systems to prevent explosion, fire and poisoning accidents and ensure safe production.
