High accuracy in-vehicle measurement

Designed for vehicle real use applications

GREENMOT has developed various torque measurement systems providing high dynamic accuracy in the “in-vehicle” real use.
Sensitive parts of these customized sensors are designed and validated by GREENMOT to be less sensitive to external perturbations like temperature, misalignment, or Coriolis effects in real use.

Applications
Engine mapping / development – Transmission development – Hybrid powertrain development
Traction control – Energy flow mapping – Engine vehicle integration
