Mandibular movement sensor
Resonant magnetic field transducer. Short (< 2.5ms) magnetic pulses of 8kHz
frequency and of very low energy are generated by the emitter probe of the
sensor. The signal received by the other probe is analysed in order to infer the
distance (d) between them.
70mm (2.75») to 235mm (9.25»)
The numerical resolution on display is 0.1mm. The resolution achieved in prac-
tical usage is linked to the distribution of noise in measurements. The effective
resolution is defined as the maximum of numerical resolution and rms noise
value. It depends on the distance between the two sensor probes:
