For the end users, we have PNP sensor proximity which is ideal. To start with, a mechanical breakdown is just one more thing that might fail. In terms of the non-contact manner, we have manifold options in ways to solve them right from 1 hence least prone method: The load cell itself works quite accurately and the settings are such that you will end up with some figures which have a low hysteresis rather than unreliable results. The environment-aware sensor (or any other name for similar thing) which react sooner(+adjusted processing time). The benefit is that your operation would be less verbose and longer so you don't need to cut off nutrients anymore when short on oil or electric, instead it will trim at a good pace of operational speed whatever suits better. The sensor is adjusted at the plant and it supports PNP that allows simple proximity to be installed or replaced. This means that you not only save time but also money. At the end of it all, these benefits translate into greater productivity and massive cost savings for enterprises. This is a common element in many organizations.
