Water activity (aw) and temperature (t) are accurately measured and the water content (x) in ppm precisely calculated. EE364 features two 4-20 mA outputs and one Modbus RTU interface.
With an optional confugration cable it is possible to perform an adjustment, set the MODBUS interface parameters and configure the analogue outputs.

The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.
Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curved is described by two parameters (A and B). These parameters are used for setting up the moisture in oil sensor for correct calculation of the water content (ppm) out of the measured temperature and water activity (aw).
Sensor replacement is possible the EE360 models when option PC4 (pluggable probe). Please see the operation manual for detail and spare part code ordering guide.
Please see the cleaning instructions.
No, coating is not available for MIO sensors.
The standard scope of supply of E+E MIO sensorsincludes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
No, mineral transformer oils from different manufacturers are quite similar.. A and B parameters are the same.
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.
