MLD Flammable

Gas Leakage detector for flammable gases

flammable gas detector

Molecular Leakage Detector for flammable gas based on ultimate MPS technology.

This flammable gas detector is a unique solution using the latest MPS (Molecular Property Spectrometry) technology to indicate the presence of flammable gases providing both a continous signal proportional to the gas concentration and the activation via relay for alarming once a prefixed (and settable) level is reached.
It combines all the advantages of MPS technology as in terms of long lifetime, no field calibration, built-in envirnomental compensation, no poisoning, wide temperature operating range and durability with a dedicated electronic board for easy interfacing the common control units thanks to the multiple outputs: Modbus, Relays and 4-20mA.

  • No field calibration
  • No cross sensitivity
  • Long lifetime 15+ years
  • Fail safe (built-in diagnostic)
  • Flammable gases concentration 5-100% LEL
  • Built-in T and Rh compensation
  • Immune to poisoning
  • Operating range -40° to 75° C, 0-100% Rh
  • Modbus, Relays and 4-20mA Output (ALL IN ONE)
