FAQ
No, coating is not available for the E+E MIO sensors.
Calibration for a specific oil is a laboratory procedure for determining the saturation curve of the oil. The saturation curve 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 for the EE360 models with the ordering code including PC4 (pluggable probe). Please see the operation manual for detail and spare part code ordering guide.
No, mineral transformer oils from different manufacturers are quite similar. A and B parameters are the same.
The standard scope of supply of E+E MIO sensors includes 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".
The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol runs on Ethernet hardware.
Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
