Applications > Dynamometer

Interface load cells are used to measure torque in dynamometers by sensing force on a fixed moment arm attached to the stationary member of the dyno. The torque is generated in the stationary member by the rotating member of the dyno. The load cell is typically mounted with hardware on both ends which accommodates a small amount of motion, such as rod end bearings. Applications are found anywhere rotating machinery is being manufactured or tested.

Industries:

• Automotive
• Aircraft
• Marine
• Electrical Power
• Farm Equipment
• Bus and Truck
• Military
• Aerospace

Testing Activities:

• Petrol Engines
• Diesel Engines
• Transmissions
• Gear Box

• Vehicle Emissions
• Brake and Clutch
• Wheels, Axles, Tyres

Load Cells:

• 1200 Low Profile Series (best for low moment sensitivity), capacities 300 to 10,000lbf
• 1500 Series (best for low moment sensitivity and low range), capacities 50 to 300lbf
• SSM Series, Capacities 50-5000lbf

Benefits:

Interface load cells are specified by leading dynamometer manufacturers. They excel in all dynamometer applications. The self temperature compensated strain gauges employed provide performance unequalled by other load cell brands, by eliminating the need for add on compensation elements which produce extra thermal; time constraints. Key benefits include:

• Low sensitivity to moments and side loads resulting from attachment alignment and wear.
• Low sensitivity to thermal gradients caused by weather and engine heat.
• Low creep error, every load cell must meet stringent creep specification.
• Low deflection and high stiffness, resulting in high natural frequency
• Low non-linearity and excellent symmetry throughout rated range in both tension and compression.
• Sealed against weather and engine fluids.
