EE371 - Dew Point Sensor for Compressed Air and Process Monitoring

The EE371 measures dew point temperature (Td) in the range -60...60 °C Td (-76...140 °F Td), with pressure rating up to 100 bar (1 450 psi). It is ideal for compressed air systems and industrial process control.

The sensor features two freely configurable analogue outputs (current / voltage) for dew point (Td) frost point (Tf) or volume concentration (Wv).

Additionally, the measured data can be read on the optional LCD display.

The robust aluminum enclosure, the swirling front-end, various process connections and sampling options facilitate mounting and operation.

  • EE354 miniature dew point sensor
    The EE354 sensor is an ideal solution for refrigeration dryers.

EE354 - Miniature Dew Point Sensor for Refrigeration Dryers

The EE354 is dedicated for dew point measurement in the range of -20...50 °C Td (-4...122 °F Td). Due to a high accuracy of ±1 % °C (±1.8 °F Td) in the typical working range of a refrigeration dryer the sensor is an optimal solution for OEM manufacturers.

The measured values are issued on the 4-20 mA analogue output or the Modbus RTU interface.

The very small design and the stainless steel enclosure with ISO or NPT thread facilitate integration into the application.

Features of E+E Dew Point Sensors

With their sophisticated, state of the art technology, the E+E dew point sensors stand for best accuracy and long-term performance in a wide choice of applications.

EE355 dew point sensor

Auto-calibration

The auto-calibration procedure employed by the E+E dew point sensors enables a working range down to -60 °C (-76 °F Td). Accurate measurement at such low dew point temperature is only possible with high-end sensing elements such as E+E's HMC01.

E+E dew point sensor

Monolithic Dew Point Sensor

The innovative monolithic E+E HMC01 combines the humidity and the temperature measurement in a single structure. This results in an optimal thermal coupling between the sensing elements, which is a prerequisite for the reproducible auto-calibration procedure.

EE-PCS configuration software

EE-PCS Configuration Software

Using the free Product Configuration Software (EE-PCS), the user can easily configure the analogue outputs, set the Modbus parameters and adjust the E+E dew point sensors. A Modbus RTU to USB converter is available as an accessory.
