The RDP Electronics LDC series are a dc LVDT transducer which makes them probably the most robust position sensor available. The term dc LVDT refers to a position sensor that has all the benefits of the LVDT measurement principle but has built-in dc to dc signal conditioning. Our dc LVDT displacement transducer units have no contact across the position sensor element ensuring very long life. The captive guided dc LVDT displacement transducer units have an internal bearing that guides the armature (the moving part of the measurement sensor). The armature of the dc displacement transducer is fitted with a male thread and the body a female thread in order to ease mounting. This type of dc LVDT transducer is appropriate for applications where the part being measured may move well out of the range of the measurement sensor.

RDP Electronics also manufacture ac LVDT sensors for use where the temperature or other environmental factors preclude the use of dc lvdt transducer units.

A mounting block is available for all 20.6mm diameter dc displacement transducers, and Spherical End Bearings for captive type transducers.
