The E+E EE31 Humidity and Temperature Transmitter provides reliable humidity and temperature measurements in demanding industrial applications up to 356°F (180°C). In addition to precise measurement of relative humidity and temperature, the transmitter calculates additional parameters such as dew point, absolute humidity or mixing ratio.

Various models are available including wall, duct and units with remote probe. The remote probe can be employed up to 356°F (180°C) and the pressure tight version up to 20 bar. The three-part design of rugged enclosure in polycarbonate or aluminum allows easy mounting and replacement. The measurands are available on two analog outputs and on a serial interface. An optional relay output can be used for alarms and process control. The optional proprietary coating protects the sensor elements against corrosive and electrically conductive pollution. The user can freely configure the outputs and perform an adjustment with the optional configuration kit.

Applications for the EE31 include:

  • Climate and test chambers
  • Process technology
  • Dryers
  • Clean rooms
  • Storage rooms
