Introduction: A main advantage of LVDT position sensors is their simplicity. Another advantage is that when there is no need for supporting bushings, bearings, and so on, the sensor can be implemented as a noncontact device, thus having a nearly infinite lifetime. In addition, typical inductive sensors with an analog output voltage have a nearly infinite resolution, determined only by the ability to read the signal over whatever noise may be present.

Applications:

One application of an inductive linear position sensor is the measurement of the extension of smaller sizes of hydraulic cylinder. The robustness of the inductive sensor lends itself well to this installation, also makes the design of the cylinder easier. Inductive transducers can be used successfully in many industrial and commercial applications. Valve positioners for process control on the factory floor are a good candidate, as well as measuring the drum position in a clothes-washing machine and other position-sensing requirements for consumer goods. 

Features:

The resolution is up to 0.1 μm and the repeatability is 1 μm;

No contact point friction, and long service life.

Customizable non-standard product.
