To measure the force being delivered by a linear actuator, we can measure the current draw of the linear actuator while it is moving. As the power consumed by the actuator is related to the force being delivered by the actuator and that the voltage will remain consistent, either 12 or 24V, the current draw will increase linearly with an increase in force. This can be seen in the Current VS Load performance graph below. Once the current draw is measured, you can use the Current VS Load performance graph to estimate the force being delivered by your linear actuator. This isn’t a perfect solution and can still be subjected to errors, but it is a good solution to estimate the force being delivered that you can compare to your design calculations. It is also a simple enough solution where you will not be required to drastically change your design to be able to estimate the force being delivered. In applications where you are moving an object in one axis, i.e. no changing angles, the current value should be somewhat stable, once moving, as the force should be constant in those applications. In hatch-like applications, i.e. with changing angles, the current values will change as the force is not constant. In these applications, you will need to track the current value throughout the operation of the linear actuator to determine where the highest force value occurs. There will also be a spike of current when the actuator starts moving, this is because the static coefficient of friction is larger than the dynamic coefficient of friction for the same materials.
