E+E EE360 Specifications
EE360
High-End
Moisture in Oil Sensor
EE360 is dedicated for reliable monitoring of lubrication, hydraulic
and insulation oils as well as diesel fuel. In addition to highly accurate
measurement of water activity (aw) and temperature (T), EE360 calculates
the absolute water content (x) in ppm.
Measurement Performance
The EE360 employs high-end E+E humidity sensing elements
manufactured in state-of-the-art thin lm technology, which are the
prerequisite for outstanding measurement accuracy.
Process Connection
The sensing probe can be employed up to 180 °C (356 °F),
20 bar (290 psi) and is available with either ISO or NPT slide tting, which
allows for variable immersion depth. Using the optional ball valve, the
probe can be mounted or removed even without process interruption.
Enclosure
The EE360 features an IP65 / NEMA 4 polycarbonate or stainless steel enclosure which facilitates installation and
maintenance. The enclosure can accommodate a 100…240 V AC supply unit or various extension modules.
Display and Outputs
The measured data is available on two analogue outputs, on the RS485 (Modbus RTU) or Ethernet-PoE (Modbus TCP)
interface and on the alarm (relay) outputs.
The TFT colour display shows simultaneously up to four measurands and offers extensive setup and diagnosis features.
The data logging function saves up to 20 000 measured values for each physical quantity. The logged data can be displayed
graphically directly on the device or easily downloaded over the USB interface.
Congurable and Adjustable
The conguration and adjustment of the EE360 can be performed either using the display and the push buttons or with the
free EE-PCS Product Conguration Software via the USB interface.

Measurement of water activity aw / water content x
The moisture in oil can be expressed in absolute or relative terms.
» Water activity aw is the relative measure for moisture in oil. It represents the ratio between the actual amount of
dissolved water and the maximum possible amount of dissolved water in the oil at a certain temperature. Independently
of the oil type, the water activity shows how close to saturation is the oil at any moment in time.
aw = 0 indicates completely dry oil, while aw = 1 fully saturated oil.
EE360 measures directly the water activity.
» The water content x is an absolute measure equal to the amount of water in the oil. The water content is measured
in ppm (parts per million) and is independent from the oil temperature. For assessing how far is the oil from saturation,
x must be regarded together with T.
EE360 calculates x out of the measured aw and T values. The calculation is oil dependent and requires a set of oil
specic parameters.
