Contactless potentiometers: Unlocking precision with magnetic sensing

Contactless potentiometers: Unlocking precision with magnetic sensing

In the evolving landscape of precision sensing, contactless potentiometers are quietly redefining what reliability looks like. By replacing mechanical wear points with magnetic sensing, these devices offer a frictionless alternative that is both durable and remarkably accurate. This post offers a quick look at how contactless potentiometers work, where they are used, and why they…

You feed it some documents, cross your fingers, and hope it doesn’t hallucinate when someone asks it a simple question. Most of the time, you get back irrelevant chunks of text that barely answer what was asked….

As regular readers may recall, I’m fond of acquiring gear from the “Warehouse” (now renamed as “Resale”) area of Amazon’s website, particularly when it’s temporary-promotion marked down even lower than the normal discounted-vs-new prices. The acquisitions don’t always pan out, but the success rate is sufficient (as are the discounts) to keep me coming back…
