FDMET400

80SD2A00121

Natural gas detector fitted with base with relay output

The FDMET400 detectors allow to signal the presence of natural gas 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.
