Most high performance racing car clutches are automatically operated during gear changes but are manually operated by the driver from the steering wheel when moving from a standstill at race starts and pit stops. During a race the driver executes gear changes by pushing a button on the steering wheel. The 'on-board' computer automatically cuts the engine, actuates the clutch and gear change. The clutch's electro-hydraulic actuation system requires two proportional measurement sensors, one on the steering wheel and one mounted next to the clutch (the feedback sensor). Active Sensors offer a number of 'motorsport ready' sensor solutions for clutch-operating systems. The sensor mounted on the steering wheel is a MHR0500 magnetic hall contactless rotary sensor and the feedback device is a high temperature contactless AC/AC LVDT sensor. The LVDT sensor has a continuous operating temperature up to 200°C (400°F) and will survive excursions up to 400°C (750°F).
