Teledyne LeCroy Test Services (TLTS) has developed a torque testing tool for CV shafts. The AT100 Torque Sensing System is designed for long term in-vehicle or dynamometer testing. No slip rings or outboard wiring are required.

The AT100 is entirely weatherproof making it an excellent choice for fleet testing. The AT100 uses non-contact, digital data transfer technology providing the user with a clean and responsive signal.

Power is inductively supplied to the rotating collar eliminating the need for batteries. The AT100 is truly a “hands off” torque measurement system, as once installed, it is invisible to the user.

TTS offers this exciting product as a turnkey installation onto the customer’s CV shaft.

Features:

Low profile for space constrained FWD applications
All weather operation
No components or wiring outboard of wheel
Digital data transfer for a clean signal
Temperature compensated
Remote shunt calibration capability
Scalable analog output
User selectable frequency response
Portability to other shafts by Teledyne Instruments
