Options
Transmitters in 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.
Implementing the Modbus RTU protocol stack makes these sensors bus compatible.
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.
