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).
