Moisture In Oil

We offer high quality oil sensors for detection of moisture in oil. These sensors allow for proper monitoring and hence saves both oil and the environment. The monitors are easy and economical to check effects of moisture in oil. Our range of equipment are lightweight and portable and saves considerable time in field testing.


Transmitter For Moisture Content In Oil

Moisture in

Oil Transmitter are specially designed for the measurement of water content in oil. It 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. For instance, moisture affects dramatically the insulation characteristics of electrical transformer oil and therefore continuous monitoring is extremely important. The measured physical quantities are water activity aw and temperature T.

With these quantities EE381 calculates the water content x (ppm) in mineral transformer oils. Calculation of water content (ppm) in non-mineral oils and lubrication oils can be achieved by programming the specific parameters of the oil into the model.

Technical data :

 

Measuring Range 0...1aw // -40...80°C (-40...176°F)
Output Transmitter: 0...1V / 0...5V / 0...10V / 4...20mA / 0...20mA

Switch: 2 potential-free relays (normally open)
Accuracy ±0.02aw // ±0.2°C
Supply 10...30V DC


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 transmitter is based on the outstanding long term stability and resistance to pollution of the capacitive sensor elements series HC.

Portable Moisture In Oil Meter

To measure various climate and processes values with a hand-held, user-friendly instrument requires extraordinary measurement technology. The selection of the appropriate sensing probe and accordingly the configuration of the hand-held meter allow for displaying the following values with the highest accuracy,Relative humidity RH,Temperature T, Dew point temperature Td, Absolute humidity dv, Mixing ratio r, Air velocity v, Water activity aw and Water content in oil x.

The robust housing allows usage in harsh industrial environments. The readability of the large illuminated display is excellent. The easy to understand menu and the practical thumbwheel navigation offer outstanding comfort. Optional carrying cases can accommodate the basic device with up to 5 sensing probes as well as accessories (calibration device with 5 ampoules calibration fluid (80% RH), factory certificate). The accuracies of the humidity / temperature probes are traceable to international standards, administrated by NIST, PTB, BEV...

PPM Meter

PPM Meter for transformer oil

Moisture In Oil Transmitter Series ACT-EE385 are specially designed for the measurement of moisture content in oil and temperature. EE385 is ideal for online monitoring of moisture in lubrication, hydraulic or insulation oil, which is very important for the long-term performance and preventive maintenance of plant and machinery.

Humidity measurement in oil Similar to the humidity in the air, the water content in oil can be indicated by the relative value aw:- 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 ACT-EE385 transmitter is based on the outstanding long term stability and resistance to pollution of the E+E capacitive sensor elements series HC.
