Sensor measuring force during pulling

[bartseger]

Hello,

I’m surching a sensor as small
As
Possible. It has to kome in a little machine to measure the force during pulling at both sides of the machine. The range of the forces’ll be between 0 and 300kg or 0 till 3000 N

Anyone can help me witj that?

The 300kg might be a challenge. It seems most ali express load cells are aimed at light weights, or weighing humans.
Here are some for lighter weights:

Here is one for 200kg:

If you can't find one that does 300kg, you could use a lever mechanism to scale the force appropriately. I also saw some adds for custom load cells, but that is more expensive.
