It is 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 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.
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.
The measured and the
calculated values are available on two free scaleable and
configurable analogue outputs. In addition, an optional relay
output can be used for alarms and process control.
