Tmaster CO/LPG/NO2 L
Detektor tlenku węgla CO, propanu-butanu LPG i dwutlenku azotu NO2
The "Tmaster CO/LPG/NO2 L" 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 L" detector are detection systems in garages and underground car parks.
It is a stand-alone unit which is a combination of a detector and a control panel, powered from the ~230V mains. It can operate as an individual device (stand-alone) or work with control panels and controllers.
Depending on the version, it can have different types of outputs;
relay - 3 relays, with NO contacts, signalling exceeding of the alarm thresholds A1 and A2 and of failures
digital - RS485 link, Modbus-RTU protocol, addressable detector.
Sensors used :
carbon monoxide CO : electrochemical, (selective, measurement or two-threshold detection, alarm thresholds : 40/100ppm, measuring range 0...500ppm)
propane-butane (LPG) : solid-state (non-selective, alarm thresholds : 10/30%DGW)
NO2 nitrogen dioxide : electrochemical, (selective, dual threshold detection, alarm thresholds : 3/6ppm ).
Visual signalling on the detector of power supply, exceeding of alarm thresholds, failure .
The detector consists of two modules : the main module (CO) and the LPG/NO2 module connected by a cable.
Main module (CO) - PS plastic housing, cable entries (glands) : 3 x PG11, PG16.
LPG/NO2 module - PS plastic housing, cable entry (gland) : PG16.
