YOUR PARTNER IN SENSOR TECHNOLOGY Humidity / Water in Oil Sensor for Maritime Applications EE36 is dedicated for the accurate and reliable measurement of moisture in lubrication oil in maritime applications and is certified according to the “Germanischer Lloyd (DNV GL)”. The device is specifically approved for use in MAN B&W marine diesel engines for instance. The outstanding long-term stability and resistance to pollution of the EE36 rests on the high-end E+E capacitive sensing element of the HC series. The monitoring of the moisture in lubrication oil is of paramount importance for the long-term performance and predictive maintenance of the machinery. The moisture in oil is described by either the absolute value “water content” x (ppm) or the relative value “water activity” aw: - The water content x (ppm) represents the ratio between the mass of water and the mass of oil. - The water activity aw is the ratio between the actual moisture content and the maximal moisture content of the aw = 0 corresponds to completely dry oil, while aw = 1 means a fully saturated oil. EE36 measures the water activity (aw) and the temperature (T) and calculates out of them the water content x. The accurate calculation of the water content of a certain oil requires a set of oil specific parameters. The measured and the calculated values are available on two free scalable and configurable analogue outputs as well as on the optional display. Additionally, EE36 can be fitted with a relay module for alarms and process control purposes. The sensing probe of EE36 is designed for continuous online monitoring. In addition to the fix installation, the use of a ball valve allows for insertion and removal of the probe without process interruption. Easy Adjustment The user can easily readjust the transmitter by using either a simple procedure with two push buttons on the printed circuit board or the free configuration software. Product Configuration Software (EE-PCS)_ The free configuration software (download at www.epluse.com) allows for easy setup of the analogue and alarm outputs, as well as for the adjustment of the water activity and temperature readings. Furthermore, the EE-PCS facilitate the replacement of the sensing element or of the sensing probe.
