The Norbar Radius Ended Torque Calibration Beam 10 – 500 ft-lbs 21430 is a precision calibration solution designed for high-accuracy torque calibration in laboratory and controlled environments, supporting both clockwise and counter-clockwise operation. Machined from aircraft-grade alloys to ±0.01% (100 microns per meter), the Norbar Radius Ended Torque Calibration Beam 10 – 500 ft-lbs 21430 delivers exceptional dimensional accuracy and long-term stability for demanding calibration applications.

Engineered to minimize energy loss during loading, the Norbar Radius Ended Torque Calibration Beam 10 – 500 ft-lbs 21430 features a bearing-free design and is carefully balanced to maximize energy transfer to the transducer. The torque radius is maintained throughout ±8° of rotation from the standard horizontal position, and the loading point is offset to reduce bending moments on the transducer, supporting consistent and repeatable calibration results.

Providing an accuracy of ±0.025% and achieving an uncertainty of applied torque of less than 0.02%, the Norbar Radius Ended Torque Calibration Beam 10 – 500 ft-lbs 21430 enables calibration to the highest class of accuracy specified by BS7882:2008. Its high torque radius accuracy allows the use of cast iron weights instead of stainless steel, provided weight accuracy is equal to or better than ±0.01%. Supplied with a UKAS certificate and manufactured in the UK, the Norbar Radius Ended Torque Calibration Beam 10 – 500 ft-lbs 21430 is an ideal choice for applications where precision, traceability, and reliability are essential.
