Wiring Recommendations

Quarter Bridge

Use 3-wire connection to compensate for lead resistance. Not temperature compensated - suitable for static measurements at stable temps.

Half Bridge

Place active and dummy gauge on same structure. Bending config: one on tension, one on compression side.

Full Bridge

Best sensitivity and temperature compensation. Use for load cells, torque sensors, and precision measurements.
