Trying to find new measurement tool.
Trying to find new measurement tool.
(OP)
Hey.
I'm might need some other perspectives for you guys because i have been thinking this 3 days allready, either way too difficultly or complitely wrong... I gotta find new measurement tool becaus the old one is going to break in any minute and is like 30yr old and it's not accurate anymore. The deal is that i havave to measure gap between two aluminium blades and there are 5 different distances with those gaps (16mm, 19mm, 20mm. 28mm and 32mm) depending on object i'm working with. Those blades slide down to busbar joint and then the compression force in the gap should be around 350-500 Newtons. I have been searching all around google but havn't found any decent solution to measureing because the 16mmm gab is so narrow. There are many suitable load cells but i just can't see the simple way how to build a proper tool with those.
Am I just missing something substantive or just badly over thinking it? I'm really not familiar with theses kind of measurement things and really hope that there is someone and gives a good hint atleast.

RE: Trying to find new measurement tool.
Can you measure force on the actuation lever and deduce the compression force from that measurement?
Can you diagram the configuration or upload a photo? Kinda difficult to envision the problem based on your description.
RE: Trying to find new measurement tool.
ok let's try again. I need to loosen or tighten the nut if the compressive force against the busbar in the gap does not meet the reguired amount of Newtons.
I might have find allready suitable solution but i'm still interested to see other possible answers.

p.s. Shim your load cell until it is the same thickness as the busbar.

Seems like you're not telling us the spatial constraints and dimensions, which is probably driving the problem.

After 35 years a handheld plastic dial Caliper or Vernier caliper, as are so common and cheap, will lose accuracy and fail. We have no idea if that's the instrument you're using! Gage blocks are a very very common tool for setting gaps and measuring. But we have no clue as to what the actual environment is, the mechanism is, the challenges are, the impediments are, what types of instruments you're using, whether they be handheld or mounted, time, space, clearance, or weight constraints, whether they give you a visual measurement or a yes/no audible signal, or anything! Unfortunately your grasp of the language and vocabulary don't help you (or us) either. We have an expression that "a picture is worth a thousand words". I suspect about 10 or 20 pictures could actually get some good help from us, but until then you'll have people throwing guesses your way and not being of much help to you whatsoever. Of course this doesn't really make anyone happy or help anyone, least of all yourself.
