Single-Supply Strain Gauge in a Bridge Configuration Reference Design

Description

This strain gauge reference design accurately measures the resistance of a strain gauge by being placed in a bridge configuration. The differential voltage of the bridge produced by variation in strain gauge resistance is amplified using the INA333. The bridge excitation voltage and INA333 reference voltage is supplied using the REF5025.

Features
  • Measured Uncalibrated Error = 0.953 %Measured Calibrated Error = 0.0154 %5 V Single SupplyOutput : 225 mV to 4.72 V2.5 V Reference VoltageThis strain gauge reference design includes theory: complete error analysis: component selection: simulation: PCB design: and measured data that correlates with theory: calculations: and simulation
