PTT-001 Online oil moisture tester/ Portable oil water content analyzer/ transformer oil moisture meter

PTT-001 Online oil moisture tester/ Portable oil water content analyzer/transformer oil moisture meter

Application
1. PTT-001 is specially designed for the measurement of water content in oil.

2. PTT-001 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.

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 PTT-001 transmitter series is based on the outstanding long term stability and resistance to pollution of the PTT-001 capacitive sensor elements series HC.

Product Versions
The physical quantities measured are water activity aw and temperature T. With these quantities PTT-001 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.
