Catalytic Acetylene Detector in ATEX Box

E709C-2

The detector is equipped with a head with a catalytic sensor element that measures the concentration of the explosive gas on the LEL (Lower Explosive Limit) scale. The detector is delivered with a pre-alarm threshold of 15% and an alarm threshold of 30% of the LEL. Optionally, an interface with Android App and a PC software are available, which allow the field testing of the detector, and the modification of detection thresholds, alarm filters, addressing, full scale, etc. The detector is equipped with an ATEX II 2G Ex-d IIC T6 Gb certified explosionproof metal box, housing both the communication electronics and the sensor element, and protected by a sintered filter in a resin-coated steel box.

  • Multiple communication modules for all kinds of applications
