You have a strain gauge with a nominal resistance of 10K and varies by only +/- 1% under maximum load. Design a circuit to measure this sensor with a output range of a full 0-5V. Part 2: If you needed 1000 different levels of digital accuracy, how many bits would you need in an ADC?

1 Answer

Use an instrumentation amplifier with a wheatstone bridge to measure the strain gauge. You need 10-bits in the ADC to get 1000 levels in the digital signal.
