Heavy-duty transmitters to measure humidity and temperature with advanced requirements. The ZC.D and ZC.DH (high temperature) transmitters are supplied with a robust, pressure die-cast aluminium housing and a stainless steel tube. The pressure-resistant version „D“ and „HD“ can be used at pressures up to 25 bar, at temperatures up to 125°C or up to 160°C. These sensors are ideally suited for industrial applications, e.g. in drying processes.

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.
