Beschreibung
Zusammenfassung:The measurement device has a control unit (16) which accommodates the actuators (17,18) which are adjustable along the axial moving direction (24) of fuel injector (1). A clamping unit is provided for receiving a clamping apparatus by which the force of the actuator (18) is acted upon the measuring rod connection, a force measurement unit and a displacement measurement unit along the axial moving direction of actuator. Bei einer Vorrichtung zum Vermessen eines Kraftstoff-Einspritzinjektors (1), der eine Steuereinheit (16) mit einem Aktor (17) und einem in Achsrichtung des Kraftstoff-Einspritzinjektors verstellbaren Stellglied (18) aufnimmt, wird der Kraftstoff-Einspritzinjektor (1) stirnseitig axial gegen- überliegend in einer Spanneinheit (35) aufgenommen, von einer Spannvorrichtung (40) beaufschlagt, wobei in einer vom Stellglied (18) beaufschlagten, in dessen Stellrichtung sich erstreckenden Messstangenverbindung (44) eine Kraftmesseinheit (46) und eine Wegmesseinheit (47) vorgesehen ist.
