Dew Point Sensor / Transmitter for Industrial Drying Processes

Open Link in Lightbox
  • Dew Point


The compact EE355 dew point transmitter with a measuring range down to -60 °C (-76 °F) Td and outstanding price/performance ratio is dedicated for applications in compressed air systems, plastic dryers and industrial drying processes.

  • EE355 Dew Point Sensor

    An integrated auto-calibration procedure leads to accuracy of ±2 °C (±3.6 °F) Td. The measured values for dew point, frost point or ppm volume concentration are available on an analog 4-20 mA and a digital Modbus RTU output. Integration into the measurement task is simplified by the compact design and the exceptionally robust stainless steel enclosure.

    With an optional Modbus to USB convertor and the free EE-PCS configuration software the user can adjust the dew point transmitter, set the Modbus parameters, and change the scaling of the analogue output.

    Key Features

    • Measurement range -60...60 °C Td (-76...140 °F Td)
    • E+E autocalibration Measurement accuracy ±2 °C (±3.6 °F)
    • Modbus RTU and 4 - 20 mA output
    • sturdy and compact stainless steel housing

    Yes. It is possible.

    EE354 / EE355 are “Sigma Compatible Probes”, for details pleas see the Sigma 05 user manual.

    For operations with the Sigma 05, the EE354 / EE355 requires manual setup (see Sigma 05 user manual) and a cable connection adapter.

    The cable connection adapter can be realized with the accessories HA010819 and HA010706.

    Low dew point means the difference between the ambient temperature and the dew point temperature is higher than 40 °C (104 °F). This corresponds to RH <5%.

    The appropriate products are the EE371 and EE355. Both devices feature an auto-calibration procedure.

    Auto-calibration is used by EE371 and EE355.

    Accredited calibration certificate for dew point temperature is available upon request, please see our calibration website.
