Can't reproduce measurings on Load Cell

[nldroid]

Hi,

I bought a load cell and fail te get it working so i tried measuring the resistance between red/white and black/white.

This is what i read on your page"

"Each cell is comprised of two resistors one which increases under load (white) and the other which decreases (black). Zero load is approx 1k, with about 2-3 Ohm change under heavy load"

My load cell behaves differently. Both sides increase when pushing on it.. Is my load cell faulty? Of do i need a different one?

be super careful how you are applying load. I have found that if do not apply load to the top of the small bridge attached to the smaller arms and ensure that the outer is correctly supported allowing the middle section to move down, then the result is often as you have found and both resistances will change in the same direction

Thanks for your quick reaction. I'll test it within your 3D part.

You're right. When i test it within the holder it changes 1 ohm each side when i push with my hand.

Thanks.
