Can Resistance Based Sensors Measure Beam Strength and Corrosion?

Click For Summary

Discussion Overview

The discussion revolves around the use of resistance-based sensors to measure the deflection and strain of corroded steel beams. Participants explore the application of these sensors in assessing beam strength and consider circuit design aspects, including the use of a Wheatstone bridge.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant proposes using resistance-based sensors to measure deflection and strain in corroded steel beams, mentioning the need for circuit diagrams and output expectations.
  • Another participant suggests that using a strain gauge would be a more straightforward solution for the measurements needed.
  • A third participant reinforces the suggestion of using a strain gauge, indicating it is the conventional method for such measurements and provides a link for further reference.

Areas of Agreement / Disagreement

There is no consensus on the best approach, as some participants advocate for resistance-based sensors while others recommend strain gauges as a more typical solution.

Contextual Notes

The discussion does not resolve the technical details of applying the Wheatstone bridge or the specific circuit design needed for the proposed sensors.

Hey guys, I'm trying to propose an appropriate resistance based sensors to measure the deflection of a beam and the strain of the metal on the underside of the beam for an old peer with steel beams which are somewhat corroded. The system has to measure the strength of these beams.
I'm trying to include simple circuit diagrams of the sensors and how they will be set up.
I'm thinking of using a wheat-stone bridge, which has four resistors to my knowledge, but not quite sure how to apply it to the bridge or how to do the circuit diagrams. What could i expect for the output of the sensors?
Any help or advice would be much appreciated, thanks.

Why not just buy a strain gauge?
 
Oh ok, thanks a lot guys.
