Clutch position and control sensors

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).

For bespoke applications we offer a comprehensive design, manufacture and speedy delivery service to satisfy the fast paced engineering developments associated with international motorsport.

AC/AC LVDT position sensors

AC LVDT sensors for automotive control and measurement systems. Advanced manufacturing techniques ensure superior sensor stablity, accuracy and repeatability in the most hostile of environments up to 200°C (400°F). Measurement ranges from 1mm to 200mm (8").

Magnetic hall contactless linear position sensors

Magnetic hall contactless position sensors are based on true solid-state 'hall-voltage/magnetic-field' measurement technology. Sensor designs are available with single or dual outputs and design benefits, include improved output signal linearization over the measurement range, overall sensor accuracy and higher operating temperatures compared to similar position sensor products.

Magnetic hall contactless rotary position sensors - high performance

Magnetic hall contactless rotary position sensors are based on true solid-state 'hall-voltage/magnetic-field' measurement technology. Sensor designs are available with single, dual and quadruple outputs and design benefits, include improved output signal linearization over the measurement range, overall sensor accuracy and higher operating temperatures compared to similar position sensor products.
