E+E EE354 Specifications

EE354
Miniature Dew Point Transmitter
down to -20 °C Td (-4 °F Td)
The EE354 was developed for monitoring dew point down to -20 °C Td (-4 °F Td). The high measurement accuracy of ±1 °C Td (±1.8 °F Td) in the typical working range of a refrigeration dryer makes the EE354 the ideal solution for OEM manufacturers. Integration into the measurement task is considerably simplified thanks to its highly compact design and exceptional robust stainless steel housing. The measurement values are issued on an analog 4-20 mA and a digital Modbus RTU output. Furthermore, excellent long-term stability and temperature compensation across the entire measurement range are important features of the EE354. Using the free EE-PCS configuration software and the Modbus USB converter (available as an accessory), the scaling of the analog output can be modified. This also permits one and two-point adjustments by the user.

Modbus Map
The measured values are 32Bit float values. The factory-set slave ID is 243 as integer 16Bit value. This ID can be customised in the register 0x00 (value range 1 - 247 permitted). For Modbus setting please see Application Note
AN0103. The factory setting of the transmission rate is: baud rate 9600, parity even, and stop bit 1.
