Explosion proof relative humidity and temperature transmitter
-40 - 180 °C | HLX30ex
The EC type examination was carried out by Physikalisch - Technische Bundesanstalt (PTB), the German national institute for science and technology.
The humidity transmitter HLX30EX consist of:
HLX30EX supply and evaluation unit, classified according to II (1) G [Ex ia] IIC subject to EC-type examination certificate PTB 99 ATEX 2042 and [Ex ia] IIC according to IECEx PTB 05.0031-1.
Sensor driver unit and sensor probe, classified according II 1/2 G Ex ia IIC T6 subject to EC-type examination certificate PTB 99 ATEX 2043 X and Ex ia IIC T6 according to IECEx PTB 05.0032X-1.
Besides measurement of humidity and temperature the HLX30EX calculates the values of the following physical quantities:
dew point temperature Td
frost point temperature Tf
wet bulb temperature Tw
water vapour pressure e
mixing ratio r
absolute humidity dv
specific enthalpy H
