DCV, Isolated 0 to 10V Output Displacement Transducer

The DCV Series transducers use the Linear Variable Differential Transformer (LVDT) principle, which means that it is probably the most robust and reliable position sensor type available. The strength of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element which for the user of the  sensor means clean data, infinite resolution and a very long life. 

This DC to DC LVDT transducer has all of the benefits of the LVDT sensor principle with the added convenience of built-in LVDT electronics enabling a dc supply and dc output.

This series of displacement transducer is available as either an unguided, captive or spring return version.

Unguided Version

On the unguided LVDTs the armature assembly is a separate component, to make a measurement the user must guide the armature inside the body without touching the sides. Unguided position measurement transducers are appropriate where external guidance is available and give truly non-contact operation

Captive Guided Version

The captive guided displacement transducer has bearings to guide the armature inside the measurement sensor. Captive LVDTs are for position measurement applications where guidance may be poor and end bearings may be required.

Spring Return Version

The spring return displacement transducer has bearings to guide the armature inside the measurement sensor and a spring which pushes the armature to the fully out position.  Spring return LVDTs are appropriate where it is not possible to connect the transducer armature to the moving component being measured.
