GasDetek Sentinel Flammable Sensor (flam)

GasDetek Sentinel Flammable Sensor (flam)


  •  Long life sensor elements
  •  Hydrophobic and stainless filters that protect the sensor element
  •  Robust housing for all environments
  •  Ease of installation and maintenance
  •  A pipe adapter can be fitted for pipe in pipe applications


GasDetek Sentinel Flammable Sensor (flam)


  •  Due to the sensors’ high quality and efficiency, these sensors can be used in commercial and industry environments such as kitchens, boiler rooms, ceiling voids, underground car parking garages and factories
  •  The design is robust but still allows for accurate and reliable detection
  •  This sensor is capable of detecting up to three programmed levels of hydrocarbon gas concentrations and is able to transmit the data to a computer at a remote location as well being used as a stand-alone detector(Stand alone sensors are calibrated for one detection level)
  •  When coupled to the Sentinel system software the sensor is able to provide all relevant information regarding the sensor status
  •  Data is continuously sent from the sensor to the computer


  •  The sensor detects gas as low as 10% of LEL (Lower Explosive Limit) which makes for a safer environment
  •  Flammable gas when leaked into the environment can pose a potentially dangerous situation for anyone present if left undetected
  •  The Sentinel flammable sensors can be calibrated to detect at different levels allowing appropriate action to be taken to avoid accidents or dangerous situations
