Strain gauge data acquisition board?

In summary, the author is looking for a small, battery powered board that will act as the wheatstone bridge, and then display the force from the strain gauges onto a digital display. If such a board exists, are there any with multiple inputs?

Ok, so what I am looking for, as the title suggests, is a strain gauge data acquisition board. Currently, we have been using all sorts of National Instruments stuff to obtain our goals. To this point they have worked fine, but now we need to seriously downsize for a new lab device we are creating.

Essentially, I am looking for a small, battery powered board that will act as the wheatstone bridge, and then display the force from the strain gauges onto a digital display. If anybody has used the little "handy boards" I would love to find something like that, but just for strain gauges.

We are using 2 shear strain gauges to make a full wheatstone bridge configuration right now. Basically, we're measuring the force on a beam. So does anyone know of a very very small self contained strain measuring device like this? Does one exist? Or are we going to have to make them/manufacture them ourselves? Oh, I should mention that in our set up we are going to have 6 beams to measure the force on. If such a board exists, are there any with multiple inputs? Thanks for any help or info!

Welcome to PF BWimer. I thinking maybe something like this?

Well, I'm afraid those all might be too "big" in a sense. Here is a little more of what I was thinking of:

Something like that, that we can battery power, hook shear strain gauges too, calibrate in some way shape or form (needs to be precise to 1 Newton), and have going to a display. The Cellmite 4327 is about the only thing I have seen that comes close to doing this. Anyone know of anything similar? Even if it was custom made, because that could be a route we have to go down...

For an unconventional idea: I read that the Wii balance board has a pretty good strain gauge bridge build in, at an unbeatable price...
 

Related to Strain gauge data acquisition board?

1. What is a strain gauge data acquisition board?

A strain gauge data acquisition board is a device that is used to collect and measure data from strain gauges. These gauges are sensors that measure the changes in strain or deformation of an object, typically due to applied force. The data acquisition board is responsible for converting the analog signals from the strain gauges into digital data that can be analyzed and interpreted.

2. How does a strain gauge data acquisition board work?

A strain gauge data acquisition board typically works by using a Wheatstone bridge circuit to measure the resistance changes in the strain gauges. The board then amplifies and filters the signal before converting it into digital data. Some boards also have the ability to perform calculations or store the data for future analysis.

3. What are the main features of a strain gauge data acquisition board?

The main features of a strain gauge data acquisition board include the number of channels or inputs it can support, the sampling rate, the resolution and accuracy of the measurements, the communication interface, and any additional features such as built-in filters or data storage capabilities.

4. What are the applications of a strain gauge data acquisition board?

A strain gauge data acquisition board is commonly used in various industries, such as aerospace, automotive, and manufacturing, for applications such as stress and strain analysis, load and force measurements, and structural health monitoring. It can also be used in research and development settings for material testing and characterization.

5. How do I choose the right strain gauge data acquisition board for my needs?

Choosing the right strain gauge data acquisition board depends on your specific application and requirements. Consider the number of channels and sampling rate needed, the accuracy and resolution required, and any additional features that may be necessary. It is also important to ensure compatibility with your existing equipment and software. Consulting with a specialist or conducting thorough research can help in selecting the most suitable board for your needs.
