Transducers – Displacement

Whilst there are several ways to measure displacement, the Linear Variable Differential Transformer (LVDT) remains a popular transducer in most industrial applications. LVDTs initially were used as a means of taking dimensional readings in laboratories. They gained popularity in a wide variety of industrial monitoring and control applications, and whilst an LVDT is used to measure displacement the technology can be employed within other transducer types.

Our LVDTs are made from stainless steel and can be sealed to most IP levels, including IP68. The rugged construction and simple principle of operation, results in high reliability and accuracy.
