Product Description 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. -

Frozen output signal, keeping the last measured value (default behaviour). ƒ Measuring Range and Accuracy The EE371 has an accuracy of ±2 °C specified within the measuring range -60...60 °C dew point. Measuring signal limitation: at medium temperature ≤20 °C (≤68 °F): Td limitation = -80 °C (-112 °F) at medium temperature >20 °C (>68 °F): Td limitation = medium temperature - 100 °C (-148 °F) -

The pipe material does have a significant influence on the response time and the lowest reachable dew point temperature. Fig. 5 illustrates how different tubing materials give off moisture over time when flushed with very dry gas after being at ambient humidity. User Manual EE371 Compact Dew Point Senor... -
