EE33 is optimised for reliable humidity and temperature measurement in applications with temporary condensation, permanent high humidity or chemical exposure. Condensation on the monolithic humidity sensor and the filter cap is prevented by controlled heating of the sensor.

The measuring principle of EE33 type J with separate humidity and temperature probes and dual heating enables precise continuous measurement even at permanent high humidity.

The remote probe can be employed up to 180°C (356°F) and the pressure tight version up to 100bar. The three-part design of rugged enclosure in polycarbonate or aluminium allows easy mounting and replacement. The measurands are available on two analogue outputs and a serial interface.

An optional relay output can be used for alarms and process control. The proprietary coating protects the sensors and their leads against corrosive and electrically conductive pollution.
