The Columbia M Series LVDTs are specially designed for applications demanding the highest levels of reliability while performing in the rugged environments that are characteristic of military programs and industrial construction equipment. These transducers consist of a coil assembly potted and mechanically swaged into a 3/8″ diameter housing with a separate moveable core. The small size and low mass of the moveable core permits its use on small, high-speed mechanisms and in sensitive, low-displacement applications.
