Miniature Dew Point Transmitter for Refrigeration Dryers

The EE354 in-line transmitter from E+E Elektronik is specifically optimized for dew point monitoring of refrigeration dryers. The high accuracy and excellent long-term stability make the transmitter a perfect solution for OEM manufacturers. Due to its compact design and small dimensions the EE354 is ideal for use in harsh applications with space constraints.

The EE354 is suitable for dew point monitoring in the range of -20°...50°C Td (-4...122°F Td). It features a high accuracy of ±1°C (±1.8°F Td) in the typical operating range of a refrigeration dryer (-3...20°C Td / 26.6...68°F Td). The built-in humidity sensor HC1000 is highly resistant to compressor oil and other chemicals. The robust, IP65 stainless steel enclosure is another quality feature of the EE354.

The measured values are available on a analog 4-20 mA output and a digital Modbus RTU interface. Using the free configuration software and the optional Modbus USB converter the scaling of the analog output can be modified. This also permits one and two-point adjustments by the user.

A ½ "ISO or NPT thread and the standard M12x1 connector for electrical connection all facilitate quick and easy integration into the measuring task.
