DatasheetThe transmitter IAW, (wall mounted), can be combined with any probe of the S series. The IAW-transmitter combined with the probe SVKA.00 (pictured here) can measure relative humidity and temperature, in air and other non-aggressive gases, for operating temperatures up to 85 °C.
The integrated hx processor can calculate further humidity values and apply them to the two outputs. With the RS485 standard all of the hx-values can be read simultaneously. Due to the digitisation of signal processing, the measurement accuracy for humidity achieves excellent values of ±1.5 % RH. In temperature measurement, the platinum resistance sensor achieves tolerances of ±0.15 K.
Both transmitterheads of the IA series (wallmount and duct mount) can be combined with any probe of the S series.
