DISPLACEMENT
ACT LVDT Displacement Transducer
œ High accuracy
œ High cycle life
œ Infinite resolution
œ Stainless steel
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.
This series of displacement transducer is available as either an unguided, captive or spring return version.
Captive guided version. Our 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.
