Industrial Humidity and Temperature Transmitter for Permanent High-Humidity and Polluted Environment
EE33
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.
EE33-M1T17 humidity / temperature transmitter with remote probe
EE33-M4 humidity / temperature transmitter with pressure tight remote probe
Humidiry Sensor HMC01
The measuring principle of EE33-T17 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.
Typical applications
- pharmaceutical and food industry
- driers for ceramics, wood, concrete, polyester etc.
