Linear Position Sensors

An Overview of Linear LVIT Position Sensor Technology
Linear Variable Inductance Transducers (LVITs) offer an excellent price-to-performance ratio compared to other linear position sensing technologies such as LVDTs and linear potentiometers. The sensor's overall length only increases by a relatively small percentage beyond their stroke. As a result, LVITs may offer better stroke-to-length ratio than many other linear position sensor technologies.

Because LVITs are inductive, the sensing element is contactless with no friction issues or moving parts that can wear out. As is common for inductive sensors, they exhibit outstanding repeatability, with resolution limited only by the electronics used with them. LVITs offer the performance of contactless sensors like LVDTs or magnetostrictive sensors, but at lower price; comparable to industrial grade linear potentiometers.
