Available Goniometer Sensor Types:
1
Specification of crosstalk for all Biometrics twin axis SG series goniometers is measured over
60
.
i.e. if a joint is moved through 60
from the neutral position in one plane without movement in the orthogonal
plane, then the sensor output in the orthogonal plane may change by a maximum
3
.
2
Life 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 a minimum of 600,000 cycles.
