EXpert G
Detektor gazów palnych
EXpert G combustible gas detectors are designed for use in stationary measurement or detection systems for high (explosive) concentrations of gases and liquid vapours outside explosive zones. They are used to detect various explosive gases and vapours, e.g. methane, LPG, hexane, pentane, ammonia, petrol and oil vapours, styrene, xylene, toluene, ethyl acetate and alcohol vapours. Compatible with a wide range of control panels and controllers. 12 V DC or 24 V DC power supply.
Depending on the version, they can have different types of output :
- current : continuous (4-20mA), or dual threshold 4/8/12mA
- voltage outputs of OC type (NC or NO), two outputs signalling exceeding alarm thresholds Al1 and Al2.
- digital - RS485 connection, Modbus RTU protocol, addressable detector.
Sensors used : semiconductor (non-selective, two-threshold detection), catalytic (non-selective, detection or measurement), electrochemical (selective, detection or measurement), infrared (non-selective, detection or measurement).
Visual indication on the detector of power supply, exceeding of alarm thresholds, failure (damage) of sensors.
PS plastic housing, cable entries (cable glands) : PG11 + PG9 (/RS485 versions only).
Areas of application : boiler rooms, warehouses, production halls, kitchens, laboratories, sewage treatment plants, etc.
