Product Description
3.1
General
The compact EE371 Dew Point Sensor with a measuring range down to -60 °C Td and a robust
stainless steel housing is ideal for OEM applications in compressed air systems, plastic dryers and
industrial drying processes. The core of the EE371 is the monolithic measurement cell type HMC200,
manufactured in thin-film technology. Due to the excellent long term stability and durability against
condensation the EE371 has low maintenance needs.
An integrated auto-calibration procedure permits a measurement accuracy of <2 °C Td. The
recommended calibration interval is 2 years.
The measured values for dew point, frost point or volume concentration are available on two analogue
outputs with 4 - 20 mA or 0 - 10 V.
