Whilst we do not sell potentiometer units, the LVDT is often a much better bet. The potentiometer has contact across the sensing element and this often results in wear on the sensing element. This cannot happen with an LVDT as there is no contact. This range of products measures from 25mm to 7.7m. They are appropriate for many applications including feedback of hydraulic and pneumatic cylinder position which are often used in injection moulding, blow moulding and die casting machines.
Magnetostrictive transducers use a magnetic interference approach to measurement.
Capacitive Capacitive position sensors measure the distance between their front face and the target without touching the target. Non-contact position sensors of this type are suitable for measurement of machine parts on a production line for example. Draw Wire Draw wire transducers, also known as string pots are effectively electronic tape measures in that they give an output proportional to the length of a spring loaded cable which is pulled out of the unit. The output of our draw wire units is either potentiometer, voltage or 4-20mA Angular Angle transducers which measure the angular position of the transducer's shaft, between 0 to 180 and 0 to 300 degrees. Angular sensors have infinite resolution and low wear.
