Diagnostic Unit OiL aging
Gear unit oiL diagnostics through thermaL anaLysis
Features
–
The perfect sensor to determine the remaining life of the gear unit oil and to reliably indicate
the right time for an oil change
–
A thermal sensor installed in the gear unit measures the oil temperature and sends this
information to an evaluation unit, which then calculates the time remaining until the next oil
change for the speci²ed oil type
–
The diagnostic unit takes the oxidation characteristics of the different oils into account under
thermal stress
Advantages
–
Reduction in oil costs
–
Optimum utilization of oil service life
–
Startup can be performed directly on the diagnostic unit (without PC)
–
Simple detection and reading of the time remaining until the next oil change
–
5 different oil types can be parameterized
–
Warning message is issued if prede²ned limit values are exceeded, such as max. oil
temperature
–
Permanent oil aging monitoring
–
Maintenance intervals can be planned individually
