Classic ebay description: "not sure what it is used for but fully working" www.ebay.co.uk/itm/Datum-Electronic-Meter/293834456606 (load cell force meter missing it's load cell)
It's not exactly like that... the load cell is a generic item and usually made to fit application; similar concept to specialty socket wrenches that fit a standard 3/8" or 1/2" drive ratchet, no matter what the brand or country of origin. This meter would have been sold new without one.
Obviously, as there is no load cell with, the claims of it being fully functional are highly suspect... however, the unit provides the power out to the load cell, so odds are pretty good that if it lights up and the display looks good, it will work properly. It most likely just got separated from some jig or bit of equipment on which the load cell was installed, and some enterprising soul has "found" it, and is trying to flip it for a quick bit of beer money.
If it were here in the GWN I'd probably bid on it; a useful tool going much too cheaply. And right now, only aboot 45 minutes remaining.

Do you read what you write? the statement "the load cell is a generic item and usually made to fit application" is a contradition of itself. the an item can't be generic and made to fit an application
Yes, load cells are generally a DC bridge but even the electrical specification e.g. excitation voltage and output can vary widely. Unusually this meter is designed to work with a range of cells but the seller could not have easily checked the meter without a load cell, even if he knew what it was. Just checking the excitiation is not enough to prove it works.
The actual item for sale is irrelevent to point of the post which is how can you say anything is fully working if you don't know what it is?
Dude... hackles down. I was agreeing with you, not attacking. In this context, a load cell is a generic thing. These things have been around for decades made exactly like this, and the load cell itself is interchangeable, no matter what the
application-specific packaging. Just like a type-J thermocouple is a type-J thermocouple, no matter what customized package it is made into.
I explained that very carefully; I guess you were too busy taking offense to consider that part.
And to take that interchangeability analogy further, industrial load cells are made to work with meters like this... they will be made in specific sensitivity ranges with a specific output curve, just like the difference between a Type J and a type K thermocouple.
In that respect, like those above thermocouples, these are a generic part.
And I agreed with you that the claims of it being fully functional are highly suspect... but at that price, I'd def take a punt on it.mnem
