Page 5: Intended Use
1.2.3 Intended Use The EE371 is intended for the measurement of dew point temperature (Td), frost point temperature (Tf) and volume concentration (Wv) in air (compressed air) and other non-corrosive and non-flammable gasses, depending on the model up to 20 bar (290 psi) respectively 100 bar (1450 psi). The use of the EE371 other than described in this manual is not allowed. -
Page 6: Product Description
The EE371 transmitter features two freely selectable and scalable outputs for Td, Tf or Wv. Modell S: The EE371 switch has two relay outputs for control and alarm purposes. The status of the two relays (configured for instance for early warning and main alarm) is indicated by LEDs. The analogue outputs as well as the Td/Tf switch threshold and hysteresis can be set with the EE-PCS Product Configuration Software, free download from www.epluse.com/configurator. -

Accuracy ≤ ±2 °C Td Accuracy not specified Air (gas) temperature Td [°C] Output signal limitation Fig. 1 Dew point measurement range and specified accuracy The maximum scaling of the analogue output is -100...80 °C (-148...176 °F) dew point. Manual EE371 Dew point transmitter... -
Page 8: Installation
Remove protection cap For accurate measurement and short response time, the sensing head shall be immersed in the air or gas to be monitored. The mounting of EE371 shall be tight; moisture ingress from the surroundings falsify the measurement results. -
Page 9: Mounting With A Sampling Cell
Please note: • Pressure gradients between the process and the sampling chamber lead to significant measuring errors. • The mounting of EE371 with sampling cell shall be tight; moisture ingress from the surroundings falsify the measurement results. Do not employ any hygroscopic materials for mounting EE371 or the sampling cell. • Keep the sampling line as short as possible. -
