Transducers and Sensors

Initial Balancing

The tolerance of the four bridge components may be such that there is a non-zero offset output voltage. This offset…

Calibration

No instrument is intrinsically perfect. Calibration techniques are used to extend the usefulness of an instrument, correcting for offsets, nonlinearity, hysteresis and…
