  • Moisture in Oil


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.

  • EE360 sensor for moisture in oil with polycarbonate enclosure

  • EE360 sensor for moisture in oil with stainless steel enclosure

  • EE360 sensor for moisture in oil - UL listed

  • NEW! Now with Extended Warranty Option

    The probe can be employed up to 180 °C (356 °F) and 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.

    The design of the enclosure facilitates easy mounting and maintenance. EE360 is available with IP65 polycarbonate or stainless steel enclosure. The measured values are available on two analogue outputs and on the optional digital interface RS485 with Modbus RTU or Ethernet with Modbus TCP. An optional relays module can be used for alarms and process control.

    The state of the art TFT colour display can show all measurands simultaneously and offers extensive error diagnostics. The integrated data logging function saves all measured data in the internal memory. The logged data can be displayed in a graph directly on the device or easily downloaded via USB interface.

    The EE360 configuration and adjustment can be performed either directly on the device via display and push buttons or with the free  PCS10 product configuration software using the USB service interface.

    Use the RS485 kit for retrofitting (order number HA010605), see the data sheet and user manual of your specific E+E product.

    The device indicates an error according to NAMUR NE43. For details, please see the user manual of your specific E+E product.

    The device has one GND connection for the power supply, an analogue output GND and an interface GND, see connection diagram in the user manual. The analogue output GND and the interface GND carry only the current output resp. interface current, which results in a more stable signal compared to a mix GND connection.

    Press 2x ► | 5x ◄ | 1x ▲ | 3x ◄ | 1x ▼ | 1x ► then select the "Configuration menu" and press ENTER. Scroll down to “Diagnosis”, press ENTER and scroll down to “Password protection” here you can see the previously set password.

    Connect the device via the USB service interface to a PC running PCS10 Product Configuration Software and read out the communication setting.

    Alternative for device with display: the display configuration menu has a section for Modbus settings (RS485, Modbus RTU) or IP settings (Ethernet, Modbus TCP) where you can see the actual setting or change it.

    Connect the device via the USB service interface to a PC running PCS10 Product Configuration Software and see at the section "Log data download" for the data memory status.

    Remote probe types can be retrofitted with an Ethernet interface using HA010606, see data sheet and operation manual of your specific E+E product.

    The device requires a firmware update. Connect the device via the USB service interface to a PC running PCS10 Product Configuration Software and confirm the update to version 1.20 or greater.

    The measured data logged by the device can only be downloaded via the USB service interface to a PC running the PCS10 Product Configuration Software.

    The pluggable remote probe has a label with the serial number close to the connector. This must be the same as the serial number of the basis device. Refer to the operation manual further details.

    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).

    No, coating is not available for the E+E MIO sensors.

    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.

    Please see the cleaning instructions.

    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".

    No, mineral transformer oils from different manufacturers are quite similar. A and B parameters are the same.
