Options
I series
Transmitters of the I series are robust, compact probe sensors to measure relative humidity and temperature with high precision. They can be used for a wide range of applications. Equipped with stainless steel sintered filters, they can be used in extreme locations near the sea, in deserts, mountains, areas with high air speeds.
Analogue output
The transmitters with analog output have a very stable signal and are available with voltage outputs.
Digital output (Modbus) with hx-converter
With the RS485 standard all of the hx-values can be read. 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.
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.
