OM375 : Compact Dew Point Temperature Transmitter for OEM Applications
|
||||||
Description
Applications :
The exact monitoring of dew point temperature in compressed air systems, dryers for plastic and other industrial processes is becoming increasingly more important.The 0M375 is designed for measurement of low dew points in OEM applications down to -60°C.The core of the transmitter is the monolithic measure¬ment cell type HMC01 developed by Omicron Sensing in thin-film technology.An autocalibration procedure which is integrated in the device and years of experience in low humidity adjust-ment make an
accuracy of <2°C Td (±3.6°F Td) possible. The transmitter has one analogue output for dew point, frost point or ppm volume concentration.
