Camshaft Timer Test Rig

Measuring Unit

Leakage values are measured by means of a highly accurate pressure control system up to 6 bar. Through a cascade of leakage-free switching valves, any flow scenarios can be set on the test item. The test rig has a total of four controllable pressure channels. The leakage is detected with a highly accurate displacement sensor in a measuring range up to 10 l/min.

The measurements are carried out at defined media temperatures, which are regulated by active cooling and heating.

Via a swivel unit the measurements can be carried out in any angular position of the test specimen.

Friction, swivel range and angular play are measured by means of an electromotive rotary axis. This axis has a highly accurate torque (measuring range +/-50 Nm, accuracy +/-0.1%) and angle sensor.

The axial forces acting on the test item are monitored with a force sensor (measuring range +/-500N, accuracy +/-1%) integrated in the torque sensor.

All measuring functions can also be performed oil-free, i.e. without a test medium, with compressed air.

Test Item Control

The test items are identified on the basis of the type code and the serial number. The configuration is selected automatically on the basis of this information.

Measurement Data Recording and Evaluation

The storage of measurement data, the creation of graphical protocols and evaluations is done automatically. During the course of a measurement, the control values of the test rig are checked for compliance with the tolerances defined in the measurement specification.
