Questions about our products?

Reliable dew point monitoring is essential for minimizing ownership costs of compressed air supply with refrigeration dryers. It allows for condition based planning of the service intervals and for avoinding breakdowns.

The EE354 dew point meter is optimised for monitoring refrigeration dryers. The measurement accuracy of ±1 °C (±1.8 °F) over the range of -3...20 °C Td (26.6...68 °F Td) and excellent long-term stability of the dew point sensor make the EE354 the ideal meter for refrigeration dryers.

Due to its compact design, EE354 can be easily installed even in tight, confined spaces. The extremely rugged stainless steel enclosure with ½ ISO or NPT thread and the M12x1 electrical connection facilitate quick and easy integration into the measuring task.

FAQ

  • What is the difference between Modbus RTU and Modbus TCP/IP?

    The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.

  • What is the difference between dew point temperature and frost point temperature?

    The dew point temperature (Td) indicates where condensation begins. The frost point temperature (Td) indicates where icing begins.

  • Is the E+E dew point probe / sensing element wettable?

    Yes, the probe and the sensing element of all E+E dew point measurement devices is wettable.

  • What calibration certificate is included in the standard scope of supply of the E+E dew point sensors?

    The standard scope of supply of E+E dew point sensors includes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see page 5 in www.kalibrierdienst.at/fileadmin/content/White_Paper_Calibration_and_traceability_in_measuring_technology.pdf

  • Can E+E supply an accredited calibration certificate with the Dew point sensor?

    Accredited calibration certificate for CO2 is available upon request, please see our calibration website.

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
