BD-Tacho_BD2510B

Features

The BD2510B Tachogenerator is famous for its robust construction and for its high accuracy
and consistent voltage proportional to speed. Brook Crompton (previously GEC) have been
continuously manufacturing the same design of tachogenerator for over 40 years, taking care
to preserve the special materials and design features which provide its unique performance.
With this wealth of experience and knowledge applied, our tachogenerators are renowned
throughout the world.
