I am on a project, where an engineer wants me to use a strain gauge.  This is the type of sensor described in this article;



I understand what a Wheatstone Bride is and how it is used for a strain sensor.  However, I have never used this sort of thing in a practical application.


While I have yet to really make a sensor selection, here is one I have started looking into,

The Omni brand SGT-1/350-TY11



Is there any guidance for interfacing a strain sensor like this with the Lab Jack?


Thank you for any advice,

First you have to make a bridge.  If you use just 1 active strain gage, you wire it to 3 dummy gages or 3 resistors to make a quarter bridge.  The best solution is often to use 4 active strain gages on your test specimen and wire them into a full bridge.


Once you have a bridge, see forum topic #4376, and in particular post #13 of that topic which is a tutorial for the U6/T7:
