电容位移传感器的一个典型案例是测量刹车盘在受力的情况下的形变。为了得到更加接近真实刹车情况下的测量结果，刹车盘必须在极端情况下进行测试。

刹车盘以2,000rpm 的速度旋转，温度高达 600°C。只有具备高测量速度或者截止频率的测量手段，才可以不被由于高温导致的，被测物体磁性和导电性能的变化所影响。 传感器探头还要提供特别高的分辨率，因为刹车盘受力引起的形变低于100μm。而德国米铱公司提供的电容式位移传感器几乎满足所有该应用的需求，是理想的选择。

To obtain accurate data on the de-formation of brake disc friction rings under stress, they must be measured under extreme conditions. Nominal speed: 2000 1/min. Surface temperature: approx. 600 °C The following demands are therefore made on the measuring system:

1. High bandwidth for frequency analyses up to the 10th harmonic.

2. High accuracy minimum zero shift with change in temperature, no change in measuring signal due to temperature-related changes in magnetic and conductive properties.

3. High resolution because deformation takes place in the range < 100 μm.
