As part of the Joint Development Agreement (JDA) with McLaren signed in August 2011 and following on from the success of the KERS project, Transense is now manufacturing torque sensor shafts for Indycar.
The shafts seen in the following video are fitted with Surface Acoustic Wave (SAW) torque sensors by Transense and extensively tested and calibrated for use within the harsh motorsport environment. The shafts are then supplied to McLaren for integration with the sensor interrogation electronics and shipment to the customer. Modifications to the Indycar shaft for sensor compatibility, the SAW torque sensor and the interrogation electronics all contain Transense patented intellectual property.
McLaren Electronic Systems develops, manufactures and deploys control and data systems for a worldwide professional motorsport market and for other automotive, transport and manufacturing applications. It is an independent trading company of the McLaren Group, based in Woking, UK.
