Tachogenerator oder Ferndrehzahlger FG 1 The teletachogenerator Type FG1 has been developed especcially for application on rail vehicles. However, it is also suitable for speed measurements on other maschines or motors.

Its place of application may be exposed to continuous heavy vibration. The teletachogenerators can also be used under unfavourable climatic conditions.

It is possible to connect either one or two display units or recording or switching units.

Interchanging of the generators is guaranteed.
