The E+E EE33-M Humidity and Temperature Transmitter is optimized for reliable measurement under demanding weather conditions. With accurate measurements of relative humidity (RH) and temperature (T), the EE33-M calculates all additional physical quantities like dew point temperature, absolute humidity and mixing ratio. A dual heating system prevents condensation on the RH sensor, on the sensing probe and on the filter cap, which leads to extremely short response time and fast recovery after condensing conditions. The measuring principle with separate RH and T probes enables precise continuous measurement even at permanent high humidity.

The monolithic HMC01 sensor is developed and manufactured with thin-film technology by E+E Elektronik. HMC01 combines the moisture and heating element on a single substrate. Condensation is prevented by controlled heating of the sensor. The proprietary E+E coating protects the sensor and its leads against pollution and corrosion.

Applications for the E+E EE33-M include:
