DatasheetThe transmitter IAW, (wall mounted), can be combined with any probe of the S series. The IAW-transmitter combined with the probe SZKA.0H (pictured here) can measure relative humidity and temperature in operating temperatures up to 200 °C. Combined with the probe SZKA.HD in operating temperatures up to 160 °C and at pressures of up to 25 bar. Additionally there is the option for resistance to ammonia.
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.
