The transmitter AK, (duct mounted), can be combined with any probe of the S series. The AK-transmitter combined with the probe SVKA.00 or SVKA.0E (pictured here) can measure relative humidity and temperature, in air and other non-aggressive gases, for operating temperatures up to 150 °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 digitization 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 A series (wallmount and duct mount) can be combined with any probe of the S series.

Capacitive MELA® sensorchips
Equipped with the highly dynamic capacitive MELA® sensor element, the sensor provides reliable performance across the full humidity range. Using the MELA® sensor element ensures long-term stability, resistance to dew formation, minimal hysteresis, and strong dynamic capabilities.
