In order to measure displacements, positions, strokes, deflections, dislocations, etc. in vehicles, machines and systems, LVDT displacement sensors with external controller are suitable. LVDT displacement sensors have a plunger which moves freely in the sensor housing. The plunger is joined to the object by a thread to transfer the movement of the measurement object. They provide extreme accuracy also under difficult ambient conditions.
As well as the version with plunger, gage sensors are also available. These are primarily used for measuring and inspecting workpiece geometry. The gages have an axial cable output and are equipped with either a plain bearing-guided plunger and spring, or with a pneumatic push rod. The sensors are suitable for high volume applications with medium requirements in terms of service life and dynamics.
