measure air temperature and relative humidity in chemically non- aggressive environments. The transmitter communicates by two galvanically separated current loop 4-20mA. Each loop has two-wire connection and each loop requires power from evaluation device. It is always nece ...

 Don´t connect transmitter while power supply voltage is on.  The cables should be located as far as possible from potential interference sources.  Installation, commissioning and maintenance may only be carried out by personnel with qualification by applicable regulation ...

Relative humidity: Accuracy: ±3.0 %RH from 5 to 95 %RH at 23 °C Measuring range: 0 to 100 %RH Resolution: 0.1 %RH Response time: t90 < 30 s (humidity step 65 %RH, constant temperature) GENERAL Power supply voltage: 9 to 30 Vdc Current output in case of error: < 3.8 mA or > 22 mA Recommended calibration ...

-30 to +80 ºC Relative humidity operating range: 0 to 100 %RH CALCULATION OF THE MEASURED VALUES Temperature: T[°C] = 6.875 x I[mA] – 57,5 Relative humidity: RH[%RH] = 6.25 x I[mA] - 25 END OF OPERATION Disconnect the device and dispose it according to current legislation for dealing with electronic equ ...
