Description

SENS SG-A1 gas alarm device is designed for continuous automatic measurement of pre-explosion 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:
- three built-in alarm relays
- vandal resistant aluminium alloy housing
- easy application and commissioning
- transit connection
- optical sensor resistant to high concentrations and aggressive and toxic substances
- continuous self-diagnosis
- local LED indication
- wide range of interfaces: SENS power line (SENS protocol); RS-485 (Modbus RTU protocol); 4-20 mA (HART Revision 6 protocol)
- five configurable thresholds
- bo...
