EXpert G
Detektor gazów palnych
EXpert G" Flammable Gas Detectors are designed for use in stationary systems for the measurement or detection of high (explosive) concentrations of gases and vapours of liquids , outside explosive atmospheres. They are designed to detect a variety of explosive gases and vapours - e.g.: methane, LPG, hexane, pentane, ammonia, petrol and oil vapours, styrene vapours, xylene, toluene, ethyl acetate, alcohol vapours. For use with a wide range of control panels and controllers. Power supply 12 V or 24 V DC.
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.
