Fixed Type Gas & Flame Detection


Catalytic 4 to 20 mA gas transmitter for detection of combustible gases and vapours.

The DTEx is an explosion proof gas detector for continuous monitoring of combustible gases and vapours in ambient air, the transmitter uses industry standard three wire analog technology and converts the signal from a catalytic combustion to 4‐20mA signal that is proportional to the actual gas concentration. The unit is designed for one‐man calibration and easy to operate. The combustible gas sensing head can be used in safety and engineering applications for oil and gas platforms, chemicals and petrochemical plants and other facilities where combustible gases are used.
