Safety instructions
EE381
!
General Safety Instructions
• Excessive mechanical loads and incorrect usage should always be avoided.
• Take care when unscrewing the filter cap as the sensor element could be damaged.
• The sensor is an Electro Static Discharge sensitive component (ESD). When touching the sensor element, ESD protective
measures should be followed.
• Grip sensors only at the lead wires.
• Installation, electrical connection, maintenance and commissioning should be performed by qualified personnel only.
1.3
Environmental aspects
Products from E+E Elektronik® are developed considering all important environmental issues. While disposing of the product
environmental pollution should be avoided. To dispose of the transmitter the individual components should be sorted with care.
The housing consists of metal (aluminium, Al Si 9 Cu 3). The electronic parts should be collected as electronic scrap and disposed of
according to the regulations in force.

PRODUCT DESCRIPTION
2.1
E+E Transmitter Series EE381 are specially designed for the measurement of water content in oil. EE381 is ideal for online monitoring
of moisture in lubrication or insulation oil, which is very important for the long-term performance and preventive maintenance of plant and
machinery.
page 18
Manual english
EE381
Humidity measurement in oil
Similar to the humidity in the air, the water content in oil can be indicated by the absolute value in ppm or by the relative value aw:
- ppm (mass of water / mass of oil)
- aw (actual water content as fraction of the water content in saturated oil)
aw = 0 corresponds to water-free oil, while aw = 1 indicates saturated oil. aw measurement with the EE381 transmitter is based on the
outstanding long term stability and resistance to pollution of the E+E capacitive sensor elements series HMC.
Model T:
The transmitter has two freely selectable and scaleable outputs for water content, temperature or ppm volume
concentration.
Model S:
The switch with two relay outputs is designed for control and alarm purposes. The status for early warning and main alarm is
indicated by LED‘s.
The optional configuration software allows flexible and easy adjustment of the analogue resp. relay outputs to the respective
requirements. The adjustment / calibration of the transmitters can easily be performed.
An optional display for on-site monitoring of the measuring values allows for a quick overview of the prevailing conditions in the process.

INSTALLATION
3.1
Installation location
EE381
Select a location that offers optimum measuring conditions. The oil must be able to circulate freely around the sensing element.
Mount the transmitter directly into the circulating system and not into a reservoir.
3.2
Installing the probe directly into the process
When installing a probe directly into the process, there should be a stop valve on both sides of the point of installation.
This makes it easy to remove the transmitter for maintenance and calibration.
Step 1:
Install the probe with the stop valves closed.
It is not permitted to use a sealing ring with a NPT 1/2“ thread.
Appropriate PTFE sealing tape or sealant should be used instead.
Step 2:
Insert the probe into the process and screw it as tight as possible by hand.
Step 3:
If there is a sealing ring, check it for correct centring and tighten the
screw connection with a torque of 30 Nm.

MAINTENANCE
6.1
Sensor cleaning
EE381
Cleaning of the measuring head is recommended before emerging in other oil and prior to calibration.
Do not touch or rub the sensing element during the cleaning process!
Cleaning of sensor from oil residue:
1) Emerge the measuring head in N-HEPTAN and swirl for approx. 30 seconds
2) Remove excess liquid and allow to air dry for approx. 30 minutes
!
6.2
Warning:
It is strongly advised NOT to try cleaning the sensor by mechanical means, such as rubbing the sensor with cotton material!
Self-diagnostic and error messages
