Bridge-Based Sensor Calibration

Last Modified: November 16, 2017

Calibrate bridge-based sensors periodically to account for changes in the physical characteristics of the sensor and in the material the sensor is measuring, to account for variations in the lead wire resistance, and to compensate for imperfections in the measurement system. Calibrating bridge-based sensors usually involves two steps: offset nulling, or bridge balancing, and shunt calibration, or gain adjustment.
