Drive shaft Torque Transducer

Drive shaft torque sensor
KA Sensors offers a service to race teams and race car manufacturers for the design and supply of dynamic torque sensors. We will either incorporate a strain gauge sensor into an existing component or build a custom sensor to suit a particular installation.  By using leading edge strain gauge techniques and state of the art electronics we are able to measure strain on drive shafts rotating at over 20,000 rpm. Our non-contact telemetry system equires no batteries and is truly a stand alone system.  Every sensor is tested and issued with traceable calibration certificate before shipping.
Some typical installations include: Half shaft torque -  Steering column  -  Drive line shafts  -  Torsion damper systems  -  Wheel dynamics   -  Test bench 
DSTS Dynamic Wireless Drive Shaft Torque Measurement Transducer

KA Sensors offers a full custom service to fit a wireless dynamic torque measuring sensor to a drive shaft. Available to both race teams and race car manufacturers the sensor can be designed, manufactured, calibrated and supplied to fit a wide range of drive shaft diameters. 

Having quickly understood a customers requirements KA will prepare the supplied shaft to have the strain gauging bonded on to it.  By using leading edge strain gauging techniques and smart amplifiers we are able to measure, amplify and correct for temperature errors in one compact assembly.  The whole assembly is then fitted with a wireless transmitter with built in long-life battery pack, along with a rugged receiver unit.

Every sensor is tested and issued with traceable calibration certificate before shipping.

With over 30 years of sensor design experience, we are able to offer load sensing solutions for almost any application.
