shear/torque strain gauges

[Bicky22]

Does anyone have a good source for shear/torque strain gauges?
I have been using these (below) forever but they are now end of life/discontinued.
I can’t find any other in this price range. < $15 pc.

Am I missing something? Any strain gauge is a torque strain gauge if it's correctly oriented...

 

[Bicky22]

Fair enough…

These are pre-oriented to 90 degrees as well as not as many leads and/or soldering to deal with vs single gauges.

I would prefer to have the product in a simpler package particularly when dealing with small diameter ( < 3/8") parts.

Further, 4 single gauges have been historically more expensive and then these preassembled and oriented gauges.

rosettes are "pre-oriented" ? and can be wired up for shear only.

another day in paradise, or is paradise one day closer ?

 

[Bicky22]

Would you be able to offer links?

I certainly can make a rosette work however this goes back to the price. I can’t find anything less than 10x the price as I was paying when I needed one of these.

Did you notice that the Omega item was priced for a bag of five?

 

[rb1957]

$200 for 5 s/g ... not too bad

Yes. Just very expensive $220 for 1 vs $12 for 2. The Omegas aren’t as high but still not attractive in comparison

Again, it is $220 for one pkg. of 5 gauges. Omega is never cheap, they are convenient and quick.
