How do you design signal conditioning for strain gauge bridges?

Strain gauge bridge conditioning: bridge excitation (precision voltage or current source, typically 5-10V), amplification (instrumentation amplifier with high CMRR for small differential signal, gain 100-1000), bridge completion (for quarter or half bridge configurations), filtering (low-pass to remove high-frequency noise), shunt calibration (known resistor to verify system), and temperature compensation (dummy gauges or coefficient matching). The bridge output is typically 2-3 mV/V full scale, requiring careful attention to noise, offset, and stability. Modern conditioners integrate all functions with auto-zero and remote sense.
