This manual describes the installation, start-up, maintenance and service of the HygroClip IW-Ex, ID-Ex, IC-Ex and IE-Ex intrinsically safe humidity-temperature probes
The document provides instructions for installing and operating the HygroClip Ex series of intrinsically safe probes designed to measure relative humidity and/or temperature in hazardous environments classified as Ex. These probes are available in four mechanical configurations: surface mounting (IW-Ex), through-wall installation with integral electronics (ID-Ex), separated probe via cable (IC-Ex), and for compressed air applications (IE-Ex). They meet European standards EN 50014, EN 50020, and EN 50284.
| Explosion protection class | II 1 G EEx ia IIC T5 resp. II 2 G EEx ia IIC T6 |
|---|---|
| FM Approval Class/Division | Class 1, 2, 3, Division 1, Groups A,B,C,D,E,F,G |
| Temperature rating (AC1301-MEX) | -60 to 105°C |
Under normal conditions of use, checking the probe every 1 to 2 years should be sufficient.
No, defective probes must be returned to the factory for repair as they cannot be serviced in the field.
The maximum cable length between the probe and HygroFlex transmitter is 200 meters.
