Clogging indicators

Clogging indicators

A rigid maintenance schedule can often lead to one of two problems: either expensive filter elements are disposed of too early on, or they are changed too late, causing the bypass valve to open and unfiltered oil to enter into the system. HYDAC clogging indicators resolve this conflict. They continuously monitor your filters’ level of saturation and precisely signal the most cost-effective and safe time to change. This process ensures continuous oil cleanliness. At the same time, operating costs can be reduced, as the service lives of the elements can be utilised to the full.

Our displays are designed for system pressures up to 420 bar. A special quality feature is the optional cold start suppression (depending on the model): it prevents false alarms during the cold start phase and ensures reliable operation even at low temperatures. For this purpose, HYDAC offers a modular system that enables easy retrofitting of the standard filters by means of screw-in mounting at any time – whether as a purely visual display for on-site service or as an electrical switch for direct connection to the machine control (PLC).

To lead your maintenance into the digital age, HYDAC offers intelligent electronic displays with analogue output (4-20 mA) or IO-Link interface. These enable true condition monitoring: the contamination level can be visualised and trends detected early (predictive maintenance). In the web shop you will find all connection dimensions as well as the corresponding CAD data (STEP) for your design. Rely on the globally proven accuracy of HYDAC indicators to raise the availability of your hydraulic systems to a new level.
