For monitoring of combustible gases and vapours or carbon monoxide
On site calibration by one person (without opening the housing), indication of measured value and system info
Measuring principle: Heat tone principle (WT) or electro-chemical principle (EC)
Suitable for control units GW-S 2.1, GW-S4.1 and GW-SK 6.1
Application
For the detection and monitoring of flammable, explosive, toxic gases or oxygen. Can also be used in dusty and dirty environments. Can be used as standalone measuring system or in conjunction with the gas alarm systems GW-S 2.1, GW-S4.1 und GW-SK 6.1 as a complete gas alarm facility for hazardous areas. Approved for operation in potentially explosive atmospheres/EX areas zone 1 and zone 2.
Description
Gas sensor with digital display in compact wall mounting housing. Diverse gases can be monitored (see ordering table). Connection cable (shielded) 3 x 1.5 mm2 Cu+ protective conductor, supply and return conductor (max. 100 Ohm line resistance). Thanks to the local display, it is possible to immediately read current measured values, perform calibration and set limit values. The concentration is output via the 4–20 mA interface for further processing.
