High-End Moisture in Oil Sensor EE360
v2.6 / Modification rights reserved | 2 EE360 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 film 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 fitting, 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 4X 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 up to four measurands simultaneously 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 via the USB interface. Configurable and Adjustable The configuration and adjustment of the EE360 can be performed either using the display and the push buttons or with the free E+E PCS10 Product Configuration Software via the USB interface.

v2.6 / Modification rights reserved | 4 The moisture in oil can be expressed in absolute or relative terms. Water activity a w 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 ▪ aw = 1 indicates fully saturated oil EE360 measures directly the water activity. 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 specific parameters. Water activity aw / Water content x Dimensions Enclosure Polycarbonate 54 (2.13) 104 (4.09) 5.1 (0.20) 180 (7.09) 166 (6.54) Values in mm (inch) Enclosure Stainless steel 75 (2.95) 5.1 (0.20) 218 (8.58) 200 (7.87) 186 (7.32) 110 (4.33) 73 (2.87) In certain applications, the oil can become corrosive over time, for example due to continuous contamination of lubricating oils by salt water in the maritime environment. In such demanding applications, the E+E proprietary protection of the sensing element leads can significantly extend the service life of the sensor. Sensor Leads Protection
