The E+E EE355 is an OEM-focused dew point transmitter engineered for reliable performance in demanding industrial applications such as compressed air systems, plastic dryers, and industrial drying processes . Its key differentiator is an integrated auto-calibration procedure that ensures long-term stability and a measurement accuracy of better than 2°C Td.

The transmitter provides flexibility with both an analog 4-20 mA output and a digital Modbus RTU interface. The analog output is scalable, and the device can measure dew point, frost point, or ppm volume concentration. The compact and robust stainless steel housing (IP65) with an M12x1 5-pin connector simplifies integration into OEM equipment . For configuration, users can utilize the optional Modbus to USB converter and the free EE-PCS software to adjust the transmitter, set Modbus parameters, and change the analog output scaling.

With a pressure rating of up to 80 bar and the ability to operate in temperatures ranging from -40 to 70°C, the EE355 is built for tough environments where reliable and accurate dew point measurement is critical.
