Biometrics Ltd ‘Q’ series single axis torsiometers are designed for measurement of rotations in one plane e.g. forearm pronation/supination or neck axial rotation. If the torsiometer is bent in planes X-X or Y-Y the output remains constant. All torsiometers function in the same way, the difference being physical size.
|Joint||Output||No. of Channels||A Max (mm)
||A Min (mm)
|| B (mm)
|| C (mm)
|| D (mm)
|| E (mm)
|Transducer Type||strain gauge|
||± 2º measured over a range of ± 90º|
|Repeatability||1º measured over a range of 90º|
|Operating Temperature Range||+10ºC to +40ºC|
|Temperature Zero Drift||0.15 degrees angle / ºC|
1Life test results have been collected by cycling the sensors through movements that would happen during everyday use. For example, placing a sensor on an adult elbow and moving from the neutral position to maximum flexion and back to the neutral position, the unit will function for typically 600,000 cycles.
