Rated 5 out of 5 by from Great performance Precise. We will keep using this sensor from Omega.

Rated 3 out of 5 by from I only buy these when I run out of others. These gages work fine once I get them installed. But the heavy wire splices near the gage complicates installation. The hook up end is just a tiny bit of bare wire - my preferred brand always makes long tinned ends which can be put directly around a screw terminal.

Rated 5 out of 5 by from PRE-WIRED STRAIN GagesS When it comes to measuring strain in various applications, the convenience and accuracy of the equipment you use can make a significant difference. In this review, we will be discussing the merits of Pre-Wired Strain Gauges, a tool that has increasingly gained popularity in the world of engineering and materials testing.

Rated 5 out of 5 by from Easy Prewired saves me the effort of soldering. I have applied these to over 20 prototype devices that require force feedback. They have functioned reliably for "long" periods of time (2 years and counting) I apply them to Aluminum plates with Loctite 401.

My application will be running at 350°F. The max temperature is listed as 320°F. Is there enough tolerance in the temperature rating of the grid/assembly, that I could use these grids for my application.

Asked by: KayB
Dear KayB we do not recommend using the strain gauges outside the operating range of : -10 to 155 (-14 to 320) You will see erroneous readings due to thermal effects. Please see HBM family strain gauges for higher temperatures: https://www.omega.co.uk/pptst/HBM-M-SERIES.html Kindly email pressure@omega,com if you have more questions

Does each linear pre-wired strain gauge contain a full Wheatstone bridge or would I have to purchase 4 to create one myself?

Asked by: Carlos12345
The KFH is a linear, single grid strain gauge. It is not a full Wheatstone bridge. Our Tech Support has emailed you a diagram of what complete Wheatstone bridge likes. Please contact our Tech Support if you have any further questions. Thank you.

Can these gauges be reused after being removed from a specimen?

Asked by: KotaAubs
Thank you for your question? Most strain gauges will not work once they have been removed from a glued surface. However you can try and have had some customers succeed in doing it onetime.
