Tmaster CO/LPG/NO2 G
Detektor tlenku węgla CO, propanu-butanu LPG i dwutlenku azotu NO2
The "Tmaster CO/LPG/NO2 G" three-gas detector is designed for use in stationary detection systems for carbon monoxide (CO), propane-butane (LPG) and nitrogen dioxide (NO2) outside potentially explosive atmospheres. Typical applications for the "Tmaster CO/LPG/NO2 G" detector are detection systems in garages and underground car parks. The detector is designed for use with typical control panels or industrial controllers. Power supply 12 or 24 V DC.
Depending on the version, it may have different types of outputs :
current : continuous (4...20mA), or dual threshold 4/8/12mA
OC voltage type (NC or NO), two outputs signalling exceeding alarm thresholds Al1 and Al2.
digital - RS485 connection, Modbus RTU protocol, addressable detector.
Sensors used :
carbon monoxide CO : electrochemical, (selective, measurement or dual threshold detection, alarm thresholds : 40/100ppm, measuring range 0...500ppm )
LPG (propane-butane) : solid-state (non-selective, alarm thresholds : 10/30%DGW)
NO2 nitrogen dioxide : electrochemical, (selective, dual threshold detection, alarm thresholds : 3/6ppm ).
Visual indication on the detector of power supply, exceeding of alarm thresholds, failure .
The detector consists of two modules: the main (CO) module and the LPG/NO2 module connected by a cable.
Main module (CO) - PS plastic housing, cable entries (glands) : PG11 + PG9 (only /RS485 versions), PG16...
LPG/NO2 module - PS plastic housing, cable entry (gland) : PG16.
