Description

The gas alarm SENS SG-A2 is designed for continuous automatic measurement of pre-explosive concentration of combustible gases and vapours, including oil product vapours in the ambient atmosphere.

It is used in modern systems of control of gases at objects of civil construction, chemical and petrochemical industry, in mechanical engineering and shipbuilding.

Main objects of operation: petrol stations, filling stations, gas filling stations, motor fuelling stations, compressor stations, gas filling stations, oil depots, gas storages, gas stations, refineries, etc.

Features:
- explosion-proof design
- easy application and commissioning
- Optical sensor resistant to high concentrations and aggressive and toxic substances
- continuous self-diagnosis
- five adjustable thresholds
- large selection of devices for fixing cable protective sheaths (metal sleeves, armoured cables, pipes)
