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. As an option we can offer a 4-20mA 2 wire connection to the
transducer on some models.
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.
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
