Hi to everybody!
I'm coming near to the world of strain gauges and the measure of low level signal (such as those generated by strain gauge) for the first time. I have to realize a deformation measuring system for the traction and compression of a rod. I want to use two strain gauges, one to measure the strain and the other for temperature compensation. So I thought to use a half-bridge configuration. Considering my lack of experience with these kinds of application (the measure of low level signals and strain gauges) I don't know if there is the possibility to buy a bridge completion module so I can complete the bridge with my strain gauges. Let me explain better: if exist wheatstone bridges (half-bridge) with two completion resistors and the other two branches of the bridge are vacant in order to connect my two strain gauges I'll buy it! Otherwise I have to create it.

Thank you a lot!

 

What does the gauge manufacturer recommend? They're usually pretty good about providing application info.

 

For my application I have choosen a linear strain gauge of HBM, to be more precise 1-LY41-3/120. The gauge manufacturer recommends his DAQ such as QuantumX, but for my application is too professional, expensive and it's no good for my application. I have to monitor suspension's strain on a race car, so this DAQ is very cumbersome and I want a system that works when the car is running.

For example I have found this product

but I don't understand how I can utilize it.
