Lubricant level switches SKF for Oils and Fluid Greases

Lubricant level switches for oils
A visual indicator in the form of an oil gauge glass, is installed on most reservoirs. It lets the operator read the lubricant level. Float switches with one to three output signals are generally used for electrical monitoring.

Design of a float switch: A permanent magnet accomodated in the float body operates a reed contact located in the tubular guide. Multiple contacts can be installed in the tubular guide at different heights, thus making it possible to flag different filling levels. An early warning can also be generated (e.g. 25 mm before the minimal lubricant level is reached).

Lubricant level switches for fluid greases

The same principle does not apply to fluid greases. In this case, capacitive proximity switches are used which normally only have one signal output. Multiple proximity switches are required in order to show multiple lubricant levels.Lubricant level switches for greases

Mechano-electrical, opto-electrical or proximity switches are used to emit electrical signals. A separate electrical switch with a discrete signal output must be used for each lubricant level to be read.
