Combustible Gas Transmitter
ATI Model (C12-17)
The combustible gas transmitter can be used anywhere gases or vapours may build up to potentially hazardous concentrations or explosive levels in ambient air.
These gases and hydrocarbon vapours such as methane, propane, butane, gasoline, toluene, hydrogen, and many others can be reliably monitored in process buildings, analyser enclosures, petrol stations, and gas compressor stations.
How it works:
Combustible gas sensors are made up of two matched sensing elements, one active and one passive. Both are electrically heated and form two legs of a Wheatstone bridge circuit.
When combustible gas contacts the sensor, the active element catalyzes the oxidation of gas, heating the active element and changing it's resistance.
The passive element remains unchanged, resulting in a change in the bridge circuit that is proportional to the gas concentration.
Features and Benefits:
- Versatility – by using this transmitter, various gases and vapours can be monitored for potential hazardous levels.
- Gas Type: Calibrated for methane unless otherwise ordered
- Display: 3-digit LCD optional
- Range: 0-100% LEL
- Response Time (T90): 10 seconds
- Accuracy: Generally ±5% of value, but limited by available calibration gas accuracy.
