Flameproof Methane Detector

  • Suitable for ATEX Zones 2 and 22
  • Stable long-life metal-oxide / pellistor sensor
  • Range 0...100% LEL CH4
  • Resolution 0,1 / 1 % LEL CH4
  • Two SPST relays option
  • 2 × 4-20 mA or 0-10 V, RS485

E2670 series is a new line of flameproof detectors and transmitters intended for use in ATEX Zones 2 and 22.

E2670 series devices are based on PluraSens® multifunctional platform.

Methane detector-transmitter E2670-CH4 utilises fully calibrated metal-oxide semiconductor or pellistor gas sensors with excellent repeatability, stability and long lifetime.

Two relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.

Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
