By synchronizing the collection of all these parameters, we can provide you with a holistic view of the brake system’s performance. For example, we can determine whether a particular noise is generated when the brake temperature reaches a certain threshold, or if it coincides with a specific level of braking pressure. This information is invaluable for automotive engineers and manufacturers as it helps in pinpointing the root cause of noise issues more effectively.
With our noise measurement system, you’re not just getting a tool to measure noise; you’re getting a comprehensive solution that empowers you to enhance the quality and performance of your brake systems.

Advanced DTV (Disk Thickness Variation) Measurement Technology for Brake Systems

In the intricate world of brake system performance, DTV (Disk Thickness Variation) plays a pivotal role. DTV refers to the thickness fluctuations of the brake disc along its circumferential path. While seemingly a minor aspect, these variations can trigger a cascade of issues that significantly impact braking efficiency and overall vehicle safety.

The Impact of DTV on Brake Performance
Any change in the thickness of the brake disc has far – reaching consequences. It disrupts the even distribution of contact pressure across the disc, leading to inconsistent friction. This, in turn, alters the effective friction radius, which is crucial for maintaining stable braking force. Moreover, as the brake disc thickness varies, it causes the brake cylinder piston to move erratically. This movement results in fluctuations in the brake pressure, which ultimately translate into unpredictable and potentially dangerous fluctuations in the braking torque.
Precision – Driven DTV Measurement with Capacitec
To address these critical issues with utmost precision, our test bench is equipped with top – tier products from the renowned American company, Capacitec. Our system features a pair of high – precision non – contact capacitive displacement sensors, accompanied by their corresponding sensor amplifiers.
These sensors are engineering marvels. Their non – contact design ensures that they can accurately measure DTV without interfering with the brake disc’s natural motion or causing any additional wear. The high – precision nature of these sensors means that they can detect even the slightest thickness variations, providing you with invaluable data for optimizing brake system performance.
Withstanding the Heat: A Key Advantage
One of the most remarkable features of our Capacitec sensors is their exceptional heat resistance. Capable of withstanding temperatures of up to 400°C, they are perfectly suited for high – temperature testing scenarios. In real – world braking situations, especially during extended or heavy – duty braking, brake discs can reach extremely high temperatures. Our sensors can operate flawlessly under these conditions, ensuring that you receive accurate DTV measurements regardless of the thermal stress on the brake system.
By integrating this advanced DTV measurement technology into our test bench, we provide automotive engineers and manufacturers with a powerful tool. It enables them to identify and rectify DTV – related issues early in the development process, leading to more reliable, efficient, and safer brake systems. Whether you’re conducting research on new brake materials, optimizing existing brake designs, or ensuring the quality of mass – produced brake components, our DTV measurement solution is your go – to choice for achieving unparalleled precision and performance.
