What makes the tuning-fork sensor so
precise?
The tuning-fork sensor measures force or mass by gauging
changes in oscillation frequency when a load is applied to a long,
narrow vibrator, and it digitally outputs the readings.
Unlike load cell or electromagnetic systems, the tuning-fork sen-
sor does not rely on material distortion, electromagnetic force,
heavy power consumption, or A/D converters, so its inherent
margin of error is extremely small, and its high precision can be
maintained for a long time.
