E+E Elektronik Compact Moisture in Oil Transmitter


EE364 is a compact and rugged moisture in oil transmitter for inline oil monitoring. It is optimised for high accuracy and excellent long term stability in lubrication, hydraulic and insulation oils, as well as diesel fuel.

  • Measuring range : 0…1 aw ,-40…80 °C (-40…176 °F) or -40…100 °C (-40…212 °F)
  • Ouputs : 2 x 4-20 mA / MODBUS RTU
  • Supply : 10-28 V DC


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 configuration cable it is possible to perform an adjustment, set the MODBUS interface parameters and configure the analogue outputs.
