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 submersible displacement transducers are designed to make measurements whilst submerged in suitable liquids.
Fluids which are non-magnetic can be allowed to flood the armature tube without affecting the operation of the
transducer.
The LVDTs are available as either unguided or spring return versions.

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
