LVDT sensor DUH

Extremely short inductive universal displacement transducer for measuring ranges up to 500mm, suitable for numerous industrial applications in hydraulic cylinders, valves, production, testing and especially in testing machines and mechanical engineering. The displacement transducer with a housing diameter of 16mm and a 5mm core has a coil unit with fully symmetrical coil design according to a regular LVDT differential transformer principle / full bridge circuit with very good linearity. The excellent ratio of measuring range to overall length allows installations even in confined spaces with up to 40% space saving.

Versions with different connections of plugs and cables as well as for operation of increased temperature and dynamics are available.

Additionall there are options with integrated electronics and with guided core to be used as a gauge / sprong loaded LVDT transducer.
