INTERNORMEN IFPM21 - Water Saturation Display

15
• The WFD 01 – Indicator is an efficient diagnostic tool to determine both the saturation
level of oil with water and the contamination level of the filter element
• It utilizes the WSPS0X (03/ 04/ 05) as well as a VS 1 series clogging indicator. It works
very reliably and fulfils all requirements of daily measurements.
• It consists of two separate and independent LED – display units with separate power
supply.
„Water Saturation Level (%)“: The LED – display for the indication of the water
saturation level is a mere indicator.
„Clogging Indicator“: The LED – display to indicate the contamination of
the filter element has two voltage free relay switch
contacts. One at 75 % and one at 100 % of the
VS1‘s nominal pressure difference range and cold
start indication at oil temperatures < 25 °C.
4.6.1. Water saturation display
- (0...70% Saturation)
The presence of free water is not likely. There is no danger of water dissolved in oil!
- (70...90% Saturation)
The presence of free water in small amounts is likely. Measures to reduce the water
content are suggested.
- (90...100% Saturation)
- Free water is present. This is dangerous for the hydraulic and the lubrication system.
Measures to reduce the water content of the fluid have to be taken
immediately!
• A calculation to the mg/kg (ppm) – water content is only possible with the 100%
saturation curve. This must be determined for every oil. Saturation curves on request.
