EE31 is optimized for reliable humidity and temperature measurement in demanding industrial applications up to 180°C (356°F). 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 180°C (356°F) and the pressure tight version up to 20bar.
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 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.

Real time monitoring of pasta drying
In order to continuously monitor the drying process, humidity sensors measure the water content of the air intake and exhaust in cycles of seconds. Defined limiting values ensure that the precise quantity of water is always removed in order to guarantee the quality of the product
Precise climate measurement for pharmaceutical applications
In addition to ensuring a comfortably warm room environment for the production and storage of goods, the primary purpose of systems where ambient conditions are critical is to maintain specified climatic conditions in the room in order to ensure product quality and to optimise energy consumption
Humidity measurement in blast furnace gas
Measurement of the absolute humidity in blast furnace gas is necessary to determine its heating value for further use. Blast furnace gas is a by-product of blast furnaces and is produced by the reduction of iron ore to metallic iron.
Drying process of paper production
Paper and paper based products like carton are manufactured in different process steps in paper machines. The main process steps are the forming, the pressing and the drying
