DECA
Driveshaft
2-channel telemetry for driveshafts, with a battery-powered rotor unit on the shaft.
The measuring chain, accuracy and outputs of DECA Telemetry, designed for propshafts and sideshafts.
2-channel telemetry with a battery-powered rotor unit for driveshafts.
DECA Driveshaft is the driveshaft variant of the DECA telemetry system. Measuring chain, signal accuracy, outputs and radio link match DECA Telemetry; the rotor unit is designed to mount on propshafts and sideshafts.
Power comes from a battery that turns with the shaft. Sensors, electronics and supply therefore sit entirely on the shaft, and the readings travel to the receiver by radio.

Measurement in the driveline
Typical measuring tasks solved with this series. The list is not exhaustive.
Vehicle development and motorsport
- Torque measurement on propshafts and sideshafts while driving
- Setting up driveline, traction and torque distribution
- Load data from testing, with no cable to the rotating side
Test bench and field measurement
- Capturing load spectra on driveshafts over longer measuring runs
- Measurements on existing shafts, with no extra shaft in the load path
- Use in harsh environments with wet, dust and vibration
Supply and sensors on the shaft
Battery on the rotating side
No power transfer to the shaft is needed, the rotor unit works on its own
