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. 


  • Ranges to 7500 lb-ft
  • Drive shaft Diameters up to 4 inches
  • Wireless communications between transmitter and receiever
  • IP65 level of sealing
  • Up to 175°F operating temperature
  • Up to 20,000 RPM
RWT-MX Series Motocross Rear Wheel Torque Transducer

Building on our success with the RWT road racing sensor we have developed a version for motocross motorcycles. The RWT-MX is designed to be a self-contained sensor unit, the rear wheel torque transducer is a direct replacement for the rear wheel sprocket carrier. The innovative design allows torque to be measured  at the rear wheel, enabling race teams to increase their knowledge, and develop their motorcycles in a way that was not possible before.

  • Self Contained
  • Lightweight
  • Wirelss Data Signal
  • +/-500Nm
  • 0.5 to 4.5V
SGT Strain Gauge - Torque

Typically this is a strain gauge applied and calibrated on a steering column or drive shaft.  This is a custom service – see separate service for the strain gauging of push rods or items where a longitudinal (not twisting) force is applied.

Typical applications include: Drive and Prop Shafts - Steering Columns

  • ±25 to ±100 Nm
  • ±20 lbft to ±75 lbft
  • Amplified Output
  • 5V or 8-16V Supply
  • Full Custom Service
