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.

If strain is dimensionless why the maximum strain is given in micrometer?

Asked by: gordo
Hi. I know strain is dimensionless but, on this website on the description of these strain gauges says maximum strain 50 000 micrometers. My question is why this strain gauges are being rating in micrometers.

How do I wire this strain gauge to Bridge data logger OM-CP-Bridge101A? Which ports on the green connector? How do I monitor 2 strain gauges on this bridge?

Asked by: Danielp
Thank you for your inquiry. Either single strain gage or full bridge is supported. Please email our Data Acquisition Group at for complete wiring details.

Whats the difference between the 2-wire and 3-wire configuration? What signal does each wire carry?

Asked by: KF978
Hi, typically 3-wire strain gauges are used for lead wire temperature compensation. If the strain gauge is a 2-wire system, strain output from the bridge is affected by the temperature effect of the lead wire. To avoid such adverse effect, the 3-wire system is adopted. If 3 lead wires are connected to a strain gage, a half lead wire resistance is applied to the adjacent side of a bridge to compensate for the temperature effect of lead wires in bridge output. The temperature effect of the lead wires connected to a measuring instrument outside of the bridge is ignored because the input impedance of the measuring instrument is high.

How to connect wires of this SG to a 3-wire input system with EXC, AI, and RC inputs, such as NI-9236?

Asked by: tackoo
Tackoo, thank you for contacting Omega Engineering. Please see page 10 of the NI9236 Manual, the 2 lead wires from the strain gauge will connect to EXC and RC, then you will have to add an external jumper across AI and RC. It might be better to contact NI if you have more wiring questions.

Are these strain gauges weldable or do these only come with adhesive?

Asked by: danladflo
We do not offer any weldable strain gages. All our gages are designed to be mounted with adhesives. The adhesives are not supplied with the strain gages and must be ordered separately. The adhesives we offer for our gages are part numbers SG401, SG496 and TT300.

Do the packs come with adhesive?

Asked by: JIMMY321354
The adhesives do not come with the strain gages. They have to be ordered separately There are 3 types of adhesives available. SG496 is a one part methyl-based cyano-acrylate adhesive. SG401 is a one part ethyl-base cyano-acrylate adhesive. The TT300 adhesive kit is a 2 part epoxy. This kit also includes the one bottle each of acetone, Acid Primer, Neutralizer & Resin Solvent.
