AF111 - LVDT Displacement Transducer

The design of the AF111 LVDT displacement transducer has evolved from technology and experience gained in over 30 years in the bespoke aerospace / military sensor market, where performance and reliability under extreme operating conditions are paramount. The transducer coil has been specifically designed to reduce overall transducer length and to enable high accuracy ratiometric operation, as well as being able to operate in the "Differential Output" configuration.

Our high performance ratiometric LVDT transducer benefits from our extensive experience in fly-by-wire control systems for flight critical aerospace applications. Using high integrity coil, screen and connection assemblies, combined with welded and vacuum brazed stainless steel construction, these LVDTs can be supplied in a range of shaft and body configurations to suit clutch, gearbox, engine and brake applications.

The AF111 range of high accuracy LVDT displacement transducers have been designed primarily for use in the ratiometric configuration and have a compact size, with stroke lengths from 5mm to 150mm. Suitable for clamp mounting, the AF111 range has a threaded, unguided core assembly to simplify installation. Suited to numerous applications, such as vehicle research, and test rigs.
