    2. Gas detection The transmitter continuously measures the detected gas concentration in the atmoshpere and converts it's current value into a 4-20 mA signal or transmits it's value to the evaluation unit via DEGA/MOBUS protocol. 3. Malfunction If a malfunction of electronics or the sensor is detected during operation, the transmitters starts transmitting via a 0,5mA current loop.
