Compact Dew Point Temperature Transmitter for OEM Applications

Compact Dew Point Temperature Transmitter for OEM Applications
Product Description

The exact monitoring of dew point temperature in compressed air systems, dryers for plastic and other industrial processes is becoming increasingly more important. The EE375 is designed for measurement of low dew points in OEM applications down to -60oC (-80oC). The core of the transmitter is the monolithic measurement cell type HMC01 developed by E+E Elektronik in thin-film technology. An autocalibration procedure which is integrated in the device and years of experience in low humidity adjustment make an accuracy of <2oC Td (+3.6oF Td) possible.
