FDGPL400
LPG gas detector fitted with base with relay output The FDGPL400 detectors allow to signal the presence of LPG concentrations lower than the lower explosive limit (L.E.L.), i.e. 10%, long before an explosive mixture is composed. The detector is equipped with a relay alarm output with contact exchange (NO and NC), a malfunction output with optically isolated NC contact and two terminals to connect a power absorption line for conventional control units.
