FIELD: control instrumentation.
SUBSTANCE: device can be used for measuring linear displacement of piston of device from automatic change in angle of injection of high-voltage fuel pump in internal combustion engines. Device for measuring linear displacement has spring-loaded measuring unit bound during process of measurement with object under control, which is disposed inside reducing bushing. Bushing has hole closed with screw. Measuring rod has free end to interact with microscrew mounted in dielectric adapter connected tightly with reducing bushing. Microscrew is electrically connected with reducing bushing through current source and signal lamp.
EFFECT: improved precision of measurement.
