2.1. Sensor installation
The
WSPS 05
is intended for inline measurements.
o
Therefore the sensor should be integrated at a circulating, respectively turbulent
point of the hydraulic system in order to generate reliable measurements.
o
Please make sure that maximum limits for flow rate and pressure are not exceeded.
o
The time to reach balance on the sensor can vary and depends on a number of
factors, such as the oil’s viscosity.
Connect the provided cable to your monitoring and evaluation system. (see also pin
assignment in chapter 5.3)
Connect the sensor cable to the
WSPS 05
by using the plug.
The sensor is now ready for operation.
2.2. Evaluating measurements
Green range (0...70% saturation)
The presence of free water is unlikely. The water solved in the oil is not a threat!
Yellow range (70...90% saturation
)
The presence of free water in small amounts is probable. Additional measurements and
actions to reduce the water content are suggested.
Red range (90...100% saturation)
Water is present in its free form. It is a threat and a potential danger of the hydraulic or
lubricating system.
Actions to reduce the water content in the fluid are urgently necessary!
The calculation to mg/kg (ppm)
– water content is only possible with the specifically
saturation characteristic.
Saturation characteristics for specific oils are available upon request.
