Application:
Online water testers are specially designed for the measurement of
water content in oil or in the air. It is ideal for online monitoring of moisture in lubrication or
insulation oil, which is very important for the long-term
performance and adaptive maintenance of plant and machinery. For
instance, moisture affects dramatically the insulation
characteristics of electrical transformer oil and therefore
continuous monitoring is extremely important.
Humidity measurement in oil:
Similar to the humidity in the air, the water content in an oil can
be described 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 the saturated oil) aw = 0
corresponds to water-free oil, while aw = 1 describes fully
saturated oil. Aw measurement with transmitter series is based on the outstanding long term
stability and resistance to pollution of the TPEE capacitive sensor elements series HC.
Product Versions:
The physical quantities measured are water activity aw and temperature T. With these quantities calculates the water content(ppm) in mineral transformer oils. Calculation of water content in non-mineral transformer oils and lubrication oils can be accomplished by downloading specific parameters of the oil
