Their disadvatage is their low selectivity - the sensor largly responds to other gases for which it is not calibrated. DEGA NBx-PL III LCD PID with a photoionization sensor The sensitive scanning method for detection of a wide range of VOC - volatile organic compounds. The sensor does not selectively detect all VOCs in the air at concentrations in ppm. -

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 protocol (RS485). 3. Malfunction If a malfunction of the electronics or the sensor is found during operation, the transmitter will continue transmitting via current loop 0,5 mA. -
