EE36 moisture in oil transmitter is optimised for use in lubrication, hydraulic and insulation oils, as well as diesel fuel. EE36 measures accurately water activity (aw) and temperature (T), and calculates water conent (ppm).

All measurands are available on two freely configurable analogue outputs and RS232 digital interface. Additionally an optional relay output can be used for alarms and process control.

EE36 is DNV GL certified as suitable for marine applications and ship industry. The probe can be employed up to 20 bar and 180 °C (356 °F). With the optional ball valve the probe can be installed or removed without process interruption.

The optional confugration kit facilitates the adjustment of EE36 and the configuration of the analogue outputs.
