I am going to vote a strong yes, it will have a strong effect on the load cell accuracy. Here is why I am thinking yes. My guess is that under the white blob is a strain gauge. I can show you numerous examples. That strain gauge is designed to work with the surface it is mounted to when a load is applied in a certain manner the pictured mounting is stressed. That stress causes the resistance of the strain gauge to change ever so slightly. The gauge itself is part of a balanced bridge so as strain or force be it tension or compression the bridge becomes unbalanced creating a small voltage change. Everything depends or hinges on that frame the strain gauge is mounted on. Altering the mounting frame in any way will sort of upset the apple cart. The strain gauge in this case looks to be mounted on a beam, the placement of the strain gauge (white blob) is critical to how much strain the beam will exhibit when a force is applied to a given point on the beam. So if we alter the beam making it shorter or even longer the resulting output will change.Will cutting the ends off and drilling holes in the load cell affect its accuracy?
