strain gauge advice

[Bicky22]

Hello everybody,

I am just for advice from experience on where to purchase some strain gauges.

• I am using them to measure torque on a 1/2” steel shaft. 10-300 in-lbs.
• I need a full bridge due to slightly elevated temperatures. ~150 F
• Unamplified signal into a DAQ system. Maybe a 5V excitation voltage?
• I would greatly prefer wire leads from the gauges (save me from soldering on pads)

I really just wanted to see if anyone has had good/bad experience from different manufactures. In the past I have used Omega. I didn’t love or hate them, the leads were kind of a pain because they were so thin but it worked very well. The 4 week lead time is holding me back from using them at this time, I am looking to buy some sooner rather then later.

Thanks everybody,
Brendan

If you've bought from Omega, then you can probably find the same brand from Digi-key. I don't know about the cost or lead time difference.

Have you tried searching on GlobalSpec's website?

I'd try Micro-Measurements.

For something like strain gages, you are probably pretty much at the mercy of the market. Maybe you should find a product you like, and stick with them, so they are inclined to favor you with a few of them, quickly, when you need them.
