The TS292K series is a three-wire 4÷20mA transmitter able to detect combustible gases by employing a catalytic sensor calibrated up to 20% LEL to different gases and find their best application in centralized alarm systems for car parks, manufacturing industries, etc. TS292KM (Methane CH4) is calibrated to detect Methane, a gas lighter than air. Its density as to air is 0.55 and its LEL (Lower Explosive Limit) is 4.4%v/v (%volume).
