Our goal is to be able to measure the force imposed on a human finger or hand by a moving part, such as a powered door, cover, sample loader, etc.. We have a digital Force Gauge that uses a load cell that measures very high forces with very little deflection or spring. Because of this, it measures very high force of a moving part because is takes some space for the motion to stop. IF you use your finger, the force seems very little because a finger has a little spring or squish to it. If we use even a small/thin piece of rubbery material with the force gauge, we get much lower, and probably more realistic force measurements.
My question to you all is how do you or how should I be performing this measurement? Is there a specific type of force gauge I should be using or is there a common squeezable material I can use to better represent a finger or hand? The IEC 61010-1 standard states to use a "force gauge which has a spring ratio of at least 25 N/mm". But I think my load cell type force gauge has a full scale deflection of 0.25mm at 1000N which is 4000N/mm. This seems very unrealistic for this application. So what is the best way to take this measurement?
