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).
