Simple Apparatus Pressostats and Thermostats, when combined with a certified switch amplifier (Zener barrier/Zener relay), can be used as “simple electrical apparatus” in Zone 1 and 2, as well as in Zone 21 and 22, according to IEC/EN 60079-11. These pressostats and thermostats are not suitable for Zone 0 and Zone 20. The use in safety relevant applications (approved electrical apparatus) is not permitted. Switch amplifiers are suitable for intrinsically safe applications. The device transmits signals from the hazardous area into the safe area. Zone dangereuse Hazardous area Potentially hazardous...
