This is the most commonly used detector in industrial installations and production processes. It can be installed at a specific detection point to detect a specific gas leak. The fixed detector is generally two-body type. The detection head consisting of a sensor and a transmitter is installed on the test site as a whole, and the secondary meter consisting of a circuit, power supply and display alarm device is installed on a safe place for easy monitoring. Its detection principle is the same as that described in the previous section, but it is more suitable for the continuous and long-term stability required by fixed detection in terms of process and technology. They also need to be selected according to the type and concentration of the gas on the site, and they should be installed at the most likely location of the specific gas, such as the most effective height of the sensor installed according to the specific gravity of the gas.
