1. Introduction
Series FTEE Online PPM Moisture Content Meter/ online Transformer oil water content analyzer/ moisture in oil transmitter is specially designed for the measurement of water content in oil or in the air. It is optimized for use in lubrication, hydraulic and insulation oils, as well as diesel fuel.
Series FTEE 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.
Series FTEE measures accurately water activity (aw) and temperature (T), and calculates water content (ppm).
2. Typical Application
Monitoring of
- Transformer oil
- Lubrication oil
- Hydraulic oil
- Engine oil
- Diesel fuel
3. Product Version
The physical quantities measured are water activity aw and temperature T. With these quantities FTEE 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.
4. Humidity/moisture/water content 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 FTEE transmitter series is based on the outstanding long term stability and resistance to pollution of the FTEE capacitive sensor elements series HC.
