EE33

EE33 Industrial humidity and temperature transmitter for permanent
high-humidity and polluted environment
  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.
Type EE33-J Humidity/Temperature Transmitter with remote probe
  EE33-K Humidity/Temperature Transmitter with pressure tight remote probe
  Humidity Sensor HMC01
Detail 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.
Typical applications pharmaceutical and food industry
  driers for ceramics, wood, concrete, polyester etc.
  greenhouses, mushroom farms
  high-humidity storage rooms
  climate, test and curing chambers
  meteorology
