Calibration Disc

• The <0.02% uncertainty of applied torque achievable with this disc allows calibration to the highest class of accuracy specified by BS7882:2008.
• Machined to +/-0.01% (100 microns per meter) from aircraft alloys.
• Clockwise and counter-clockwise operation.
• Capable of SI or Imperial calibrations.
• Compatible with male and female 1/4" square transducer drives.
• No bearings to cause energy loss during loading.
• Brass weights with an accuracy better than +/-0.01% are available in five sets to achieve a variety of calibration ranges.
• Special weight sets can be specified up to a maximum torque of 2.5 N.m.

Radius Ended Beams

• The <0.02% uncertainty of applied torque achievable with these beams allows calibration to the highest class of accuracy specified by BS7882:2008.
• Machined to +/-0.01% (100 microns per meter) from aircraft alloys.
• Clockwise and Counter-clockwise operation.
• All have interchangeable square drive to increase flexibility of use.
• Torque radius maintained throughout +/-8 degrees of rotation from horizontal.
• No bearings to cause energy loss during loading.
• Balanced to maximise energy transfer to transducer during loading.
• Loading point offset to reduce bending moments on the transducer.
• High torque accuracy allows use of cast iron weights rather than stainless steel. Weight accuracy is required to be equal to or better than +/-0.01%.

5000 lbf.ft Calibration Beam

• The <0.04% uncertainty of applied torque achievable with this beam allows calibration to the high classes of accuracy specified by BS7882:2008.
• Beam length machined to +/-0.01% (100 microns per meter).
• Clockwise and Counter-clockwise operation.
• Beams balanced to maximise energy transfer to transducer during loading.
• High beam accuracy allows use of cast iron weights rather than stainless steel. Weight accuracy is required to be equal to or better than 0.01%.
• High quality bearings to reduce energy losses.
• Gearbox provided to level beam and remove cosine errors.
• SI and Imperial Calibration possible with one beam (using different weights).

Designed to remove potential sources of measurement error, these Discs can be used to calibrate Norbar torque transducers, and torque transducers from other manufacturers (where design permits), as well as mechanical test devices. UKAS length certification is provided with each Disc. Note: A temperature controlled environment is essential for use of these beams. The selection of weights will be influenced by gravitational constant and air buoyancy values at the proposed laboratory site.
