We are using a load cell as shown below, the data sheet for which can be found on this link.
The load cell needs to coupled with a plunger as shown below.
The plunger is supposed to measure the axial force acting on it. Initially, we had just stuck the plunger with the help of glue on top of the load cell. But with this setup, if the force acting is not completely axial, it tends to cause a moment which leads to incorrect measurement of the force.
We are interested in knowing a reliable way of coupling to solve the issue. Also, we would like to know if there is some reading reference available regarding this.
