In the field, most tensioners are oversized and we use prescribed tensioning techniques, but what usually happens is that you simply "get up on them" until the belt sag is where you want it and it tracks somewhere near true.
Again , I am not sure from your question if this will be of any help.

I personally find load indicators a pain in the neck. Just more parts to look after. A good , calibrated torque wrench in the hands of one of my apprentices was all that was ever necessary to keep up with the inspectors requirements, even on the biggest jobs. With the advent of TS bolts, even that was not necessary. (Keep in mind that TS bolts are definately not the perfect solution on a construction site, just the best so far. Quiet, easily inspected but, resulting in bad connections if not properly bolted up and with ALL THOSE LITTLE ROUND THINGS EVERYWHERE!)
I am old enough to have been on a job that used RIVETS!!! I didn't know much then, but now I look back with a certain nastalgia. Rivets ARE a macho thing , you know. Of course, I am somewhat deaf in my right ear---but that's another story----
