Hydraulic systems, pneumatics

Valves are responsible in hydraulic systems and pneumatics that forces are routed where they are needed. Automatically functioning valves must also be checked for function which can best be achieved using displacement sensors. This also applies for many other components where the displacement measurement can also be completely integrated depending on requirement.

A desired or undesired expansion of an object is always combined with a temperature change. This can already start or prevent a minimum expansion process. Several product groups are available for monitoring ...

Filling level

A filling level measurement situation can arise with a liquid substance as well as with dry, bulky goods. The precise measurement of liquid levels is difficult to achieve, nevertheless, the confocal measuring ...

Liquid level

Precisely measuring the level of liquids is known in measuring technology as difficult to achieve. Nevertheless, the confocal measuring technique is suitable as a very good solution for this problem. Light ...

Piston position in hydraulic valves

In hydraulic drives proportional and servo valves control the volume flow of hydraulic oil. In order that an exact dosage, and therefore a controlled movement is possible, displacement sensors are integrated ...

Dosing systems for high-viscosity glues

In the automotive industry piston dosing systems are used for glueing car windscreens and windows. These dosing systems supply the highviscosity glue to the application gun in an exactly controllable way. ...


Measuring oscillation is a frequently occurring measuring task. Oscillations occur in research and development, in machines and plant construction as well as production control and are measured using sensors. ...

Lubrication gap

Sliding bearings are used for crankshaft bearings in the engine. A specific minimum distance is required so that the bearing operates as wear-free as possible. Miniature eddy current sensors are integrated ...

Pneumatic slide valve position

Pneumatic control valves are employed in chemical engineering for regulating liquid and gaseous media. In order to achieve a constantly high level of process reliability, the flow rate must be controlled ...


The control piston in a valve controls the oil flow to the hydraulic cylinder. As the piston moves back and forth, drilled holes in the valve body are covered and uncovered. The piston is moved by a linear ...

Inspection of valve cones

During the automated assembly of cylinder heads, the proper seating of the valve cones is monitored with optoNCDT laser-based triangulation sensors. This prevents valves from dropping into the combustion ...
