These transducers are for displacement / position measurement. They make an accurate position
measurement of the movement of the armature (the sliding part) relative to the body of the displacement
transducer.
This transducer uses 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.
Our 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 our 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
