EE300Ex HUMIDITY / TEMPERATURE SENSOR User Manual
●General
◆The EE300Ex-M1 and the EE300Ex-M3 intrinsically safe sensors are intended for the measurement of relative humidity (RH) and temperature (T) or temperature alone, in the explosion hazard areas, in gas and dust up to Zone 0/20. The entire device can be placed in the explosion endangered area.
◆The sensor may only be powered by an intrinsically safe power supply device or protective barriers.It features a 2 wire 4...20 mA design and has two individually scalable analogue outputs.
◆In addition to the measured RH and T, the EE300Ex-M1 calculates also the following parameters:
▼ Absolute humidity dv
▼ Wet-bulb temperature Tw
▼ Specific enthalpy h
▼ Dew point temperature Td
▼ Frost point temperature Tf
▼ Mixing ratio r
▼ Water vapour partial pressure e
