Schaeffler GreaseCheck
Technical description
The condition of the grease is determined by means of an optical
reflection method.
For this purpose, the sensor head is immersed in the grease.
Monitoring of the grease is carried out on the basis of characteristic
changes for automatic condition assessment.
A cable provides communication between the sensor head and
the electronic evaluation system.
The measurement depth of the sensor head extends only a few
millimetres into the grease. There must be grease directly in front
of the sensor head for measurement. Air inclusions can lead to
incorrect measurements.
The optimum measurement point will vary from one application to
another. The sensor must not record grease in direct rolling contact.
The grease conditions present in areas adjacent to the raceway will
allow comparable measurement results.
GreaseCheck gives the following output data:
■
water content
– the change in water content of the measured grease relative
to fresh grease or respectively to a defined upper limit
■
grease deterioration
– the change in turbidity and ageing of the measured grease
relative to fresh grease or respectively to a defined upper limit
■
temperature
– output of the current temperature of the grease.
