Simple and fast
sensing and reading of the oil temperature and its remaining service life.
warning messages issued if the predefined limit values, such as max. oil temperature, are exceeded.
maintenance intervals allow optimum utilization of oil service life and reduce maintenance costs.
The DUO (Diagnostic Unit Oil aging) diagnostic unit carries out a thermal analysis on your gear unit oil. A thermal sensor measures the oil temperature and sends this information to an evaluation unit, which then calculates the time remaining service life for the specified oil type.
All you need to do is define the limit values so that DUO can send you a warning message when they are exceeded. In practice, this means that you can keep an eye on the remaining oil service life – and thus the performance – of your mechanical drive technology at all times.
Diagnostic units are the perfect partner to our gear units. They help to monitor the remaining oil service life during operation, perform diagnostics and optimize maintenance intervals.
All of these facts make these diagnostic units an important component of any condition monitoring concept.
