Displacement Sensing Products
-
Ideal for precise micro-position measurements, our miniature linear variable displacement transducers (LVDTs) provide accurate, repeatable measurement. Inductive contact, non-contact, slide, and spring-actuated sensors are available in various stroke lengths-- ideal in spaces where traditional LVDTs are too large. Our sensors operate in harsh environments over millions of cycles without degradation in performance

Linear Variable Differential Transformer (LVDT) and Rotary Variable Differential Transformer (RVDT) are transformer-type voltage/current transducers that convert a linear/rotary movement of a core/shaft to a multi-wire differential AC electrical signal. Both deliver signals linearly proportional to the position of a shaft (magnetic induction core). An LVDT/RVDT simulator is used to convert digital positional commands to corresponding AC signals.

Linear Variable Differential Transformers (LVDTs)
-
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.

A linear variable differential transformer (LVDT) is a type of electrical transformer/transducer used for measuring linear displacement (position). A counterpart to this device used for measuring rotary displacement is called a rotary variable differential transformer (RVDT). The RVDT is like an LVDT in that it measures a positional displacement, however, the displacement, which is still a linear proportional function, is based on rotary instead of linear positional movement.
