Control of today’s method systems vary from complete pc systems to operators manually dominant valves. One area of process control is valve automation. While valve automation will seem to be a really intimidating task, especially when compared to simple pull handles, there are a few common tools whose understanding can go a long way to serving to users feel comfortable automating their processes. This post will focus on limit and proximity switches, what they are, and how they are different.
