Conductive Plastic Potentiometers in Crash Testing

Even as the trend in linear and rotational measuring technologies is headed towards non-contacting principles, potentiometer-based sensors are still largely unrivaled for many applications. Their positive characteristics are keeping these sensors ever popular and this is unlikely to change much. After all, comparable measuring speeds, linearity values, resolutions, hysteresis values, and temperature ranges would otherwise entail significantly higher costs and efforts. Now, the versatile "pots" are once again proving their strengths in an application involving crash test dummies. A linear potentiometer, made of conductive plastic and customized to the application, is playing a key role.
