Teledyne LeCroy Test Services (TLTS) offers a unique Automotive Torque testing tool, the RT100D Torque Sensing System, designed for long term in-vehicle or dynamometer testing. No outboard wiring or slip rings are required.

The RT100D is entirely weatherproof making it an excellent choice for fleet testing. The RT100D uses non-contact, data transfer technology providing the user with a clean and responsive signal. Power is supplied to the rotating collar inductively eliminating the need for batteries.

The RT100D is truly a “hands off” torque measurement system, as once installed, it is invisible to the user. TLTS offers this exciting product as a turnkey installation onto the customer’s driveshaft.

Features:

• Operates in rain, snow and mud
• Designed for unattended testing
• Shunt calibration from inside the vehicle
• Analog output with 1 kHz frequency response
• User selectable scaling
• Collar projects 0.62 inches from shaft diameter, 3.9 inches long
• Custom form factors available
• Turnkey installation available with 0.5% accuracy NIST traceable
• Temperature compensated -15 to +75°C, -40 to +120 available
• No batteries or slip rings
• Non-critical antenna placement (±0.75 inches)
• Light weight collar does not present balance problems
• Racing and dynamometer units available
• Two channel versions available for measuring thrust, strain or temperature

Applications:

• Transmission development
• Engine development
• Powertrain torque monitoring
• Traction control
• Racing vehicles
• Fleet testing
• Customer use testing
