Low Cost (eBay) load cell, proper mechanical application

Using Arduino Sensors

I want to setup a "?????" beam load cell. Something likeThis
Not sure the proper term for this type of cell (beam / single point .....)

But, I'm not sure the correct mechanical structure. In the below sketch, Type 1 results in a force and a torque.

Type 2 results in only a force (assuming the force is a single point)

I've looked through a large number of loadcell mfg websites and could not find a definitive answer.

Does anyone have some insight into what this type of load cell expects?

Thanks
John

Only done a few projects using load cells here.

Iā€™m confident you have seen this but here it is anyway.

What is your application? Do you want to make a weight machine or something else?

I found this datasheet for a similar load cell.

It states that both Type 1 and Type 2 load configurations will work properly.

Will have to purchase and test.

Don't have a specific application, would like to be able to measure static torque and force. I would design the mounting for however the load cell works and figure out the rest.

Thanks, I had seem similar. It seems either will work fine... but we'll see.

I will post whatever I've found as it seems what I think would be a simple answer is never stated clearly (at least for me).

Platform load cells are designed to be insensitive to the location of the load, within limits. For example, one of the following vendor's cells is intended for use with a 600 mm x 600 mm tray or platform. They are also known as single point load cells (counter-intuitively for me).

Thanks your link was just the info I needed.

BTW I think the "single point" name may be a reflection of their ability to accept a load at a single point. Just a guess.
