Overview

The DT-S is an automatic high-precision measurement system for Disc Thickness Variation (DTV) and Lateral Runout (LRO) of brake rotors. 
These conditions are the major causes of brake chatter/judder and can ultimately lead to premature NVH problems. 
The system provides the user DTV and Runout data in a three-dimensional imaging format, thus helping in investigation and analysis of geometric structure deformation caused by over-heating and excessive mileage on the brake rotor.

Features

• 1. The sensors scan the full surface of the friction part of the brake rotor with the selected track width automatically.
• 2. A precision air bearing spindle supports the rotor while an air bearing slide holds the capacitance sensors to keep accurate measurement for long lasting performance.
• 3. A universal fixture is used to minimize the need for multiple fixtures and easily accommodates a wide variety of rotor shapes and sizes.
• 4. Fixture accuracy check feature provides reliable measurement and maintenance.
• 5. Versatile analyzing software by “Sunware DT-S”
