Many disciplines within the automotive community have a need to measure in-vehicle driveline torque during testing. These include engineers testing transmissions, engines, clutches, differentials, ABS and traction control systems, tires, suspension components, and active suspension systems.

Efforts to reduce emissions and improve vehicle efficiency also require accurate and non-intrusive techniques of measuring torque and horsepower. Fleet and customer use testing are emerging as important development tools for automotive engineers who want to collect real world data.

Teledyne LeCroy Test Services offers a variety of products used by automotive manufacturers and their suppliers to measure torque in these critical powertrain components.

Applications: Transmission Development — Engine Development — Powertrain Torque Monitoring — Traction Control — Racing Vehicles — Fleet Testing — Customer Use Testing

FPT100D Engine Torque Measurement System

The FPT100D is a non-contact torque sensor system designed to measure engine output torque by instrumenting the existing flex plate or flywheel—without requiring any modifications to the powertrain. It’s ideal for engine mapping, hybrid powertrain development, and transmission calibration, offering high accuracy and robust performance in demanding environments.

  • Replaces existing flex plate/flywheel — no extra space needed
  • Measures piston pulses and engine harmonics
  • Inductively powered — no batteries or slip rings
  • Digital data transfer for clean, interference-free signals
  • Scalable analog output (0±5V or 0±10V)
  • Temperature-compensated output
  • User-selectable frequency response (2, 20, 200, or 2000 Hz)
  • NIST traceable with 0.5% full-scale accuracy
  • Remote shunt calibration capability
  • Two-channel versions available for thrust, strain, or temperature
  • Racing and dynamometer units available
