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
