Measurement of Fuel Injectors

The patented Werth Fiber Probe is used around the world for measuring fuel injectors used in modern diesel, gasoline and aircraft engines. This tactile-optical sensor can have a contact sphere with a diameter between 20µm and 300µm. The Werth Fiber Probe makes it possible to measure the cylindricity and diameter of the tiny injection ports, as small as 80µm, in 3D spatial orientation.

Fiber Probe Scanning has recently been implemented. The extremely high measurement point density provides another increase in precision and reliability. The WinWerth "Injector" application has also been expanded to include the measurement of reverse tapered holes.

Together with a high-precision multisensor coordinate measuring machine from the Werth VideoCheck EA series, measurement deviations of less than 0.5µm are achieved.
