Gas detection signaling device UDAR-STG.

The device allows to detect dangerous concentration of combustible gases (methane, propane, etc.) in the air, generate an alarm notification and send a signal to activate the anti-explosion system.


  • Detection of combustible gases at a concentration of 10% of the explosive volume
  • High noise immunity
  • Emission of alarm notifications according to two thresholds of combustible gas concentration
  • Semiconductor sensitive element with a long service life
  • Low power consumption
