电位位置传感器广泛应用于许多行业。汽车行业的应用最为明显和重要。位置传感器通常由聚合物电阻元件和滑动电接触器或由各种贵金属或合金制成的“擦拭器”构成。电噪声和磨损通常与此类位置传感器相关。位置传感器中的接触器提出了一种新概念，该概念使用碳纤维形成接触尖端，从而产生异常大量的接触点。初步测试表明该系统的电气性能和耐用性得到了改善。本文讨论了使用这些碳纤维接触器的位置传感器的设计要求和性能特征。
Potentiometric position sensors are widely used in many industries. Applications in the automotive industry are most apparent and important. The position sensors are typically constructed with a polymer resistive element and a sliding electrical contactor or "wiper" that is made from various noble metals or alloys. Electrical noise and wear are often associated with such position sensors. A new concept for contactors in the position sensors has been proposed that use carbon fiber to form contact tips that result in an exceptionally large number of contact points. Preliminary tests have demonstrated improved electrical performance and durability with this system. This paper discusses the design requirements and performance characteristics of position sensors using these carbon fiber contactors.
