Pressure build-up time measurement
When measuring the pressure build-up time, Tietjen uses the Conformity Test Unit (CTU) from WABCO. The response and pressure rise behaviour upon receipt of a pneumatic control signal is checked at the wheel brake cylinder with the worst position.
The CTU (Conformity Test Unit) can be used for these measurements:
- Capacity check of the tanks at the tractor vehicle and the trailer
- Build-up time measurement at conventionally- and electronically-controlled pneumatic brake systems at the tractor vehicle and the trailer
- Compatibility check for tractor vehicle and trailer interfaces – pneumatic and electronic
- CAN data line and CAN data transmission check
- CAN data review
