Monitor the temperature and remaining gear unit oil service life of your drive technology with simple thermal analysis – at any time, even during production. The benefit to you: DUO's measurements allow you adjust the maintenance intervals of your gear unit perfectly to suit your work processes. This makes planning those processes much easier, and increases the efficiency and economic viability of your machines and systems.
Keeping an eye on the remaining service life of your oil

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.
