Thanks for your responses, so looks like power consumption can be managed, these strain gauges do not take much, just send the power when measuring. Got it.
I have seen these strain gauges, but they all look like they need to be built into a package to use. Similar to bathroom or kitchen scales......to avoid the difficulties of having to build this my self, I was hoping to find something that could be used without having to create a cantilever setup....just basically place on a platform and get results......this will be used with jars, around 4 - 6 inch in diameter
