I need to select and install load sensors on atribo-corrosion device. To briefly explain our setup, we are using a ring-on-flat tribocorrosion tester. In this configuration, the flat disk counterface is attached to an actuator that moves in a reciprocating motion, while the ring remains stationary and applies a normal force to the moving disk. The normal force is applied using a deadweight method, where the ring presses onto the disk.
Our goal is to measure the friction coefficient, which requires us to determine the normal force applied by the ring to the disk, as well as the tangential force during their contact.
The estimated maximum values are as follows: Normal force: Approximately 200 N. Tangential force: No more than 150 N, depending on the friction coefficient.
Given the potential cost of the sensor, we need a measurement accuracy of at least 0.1% of the force.
Which type of load cell with the lowest price Can do that for us? Can we a 2 axis load cell?
If you have any option it would be greatly appreciated if you could help me.

Best regards
