Buyers searching for “conveyor protection” trip over three similar names: zero speed switch, speed switch, and slip switch. They sound like the same device with a different label, but they catch three different failures — and picking the wrong one leaves a real gap in your protection. I’ll set the three side by side, show […]
Every few weeks a plant engineer tells me the same story: a chain broke on their scraper conveyor, the line kept running for a few seconds, and by the time someone hit the stop button three meters of flight pan were wrecked. “How would a zero speed switch have prevented that?” they ask. The answer […]
Vibration monitoring with accelerometers is the quiet workhorse behind most predictive maintenance programs, and it is also the easiest one to start small. A healthy rotating machine has a repeatable vibration signature; as bearings wear, couplings misalign or impellers go out of balance, that signature shifts weeks or months before anything actually breaks. Catch the […]
Picking the right industrial accelerometer is less about finding the “best” sensor and more about matching one to the machine in front of you. Engineers usually come to us with a symptom — a motor that sounds wrong, a tower that sways, a press that kicks — and the job is to translate that into […]
When a procurement officer emails me asking for “the most accurate tilt sensor Drksir makes,” I almost always answer with a question first: “How big is the real movement you need to capture?” It turns out that about 80% of the time, the 0.001° flagship is overkill for the job. And the other 20% of […]
When an engineer emails me asking, “The sensor reads 0.3°, but my drawing shows the pier moved 12 mm — which one is right?” my answer is always the same: both, once you convert. A tilt sensor reports an angle. Your structural report, your machine spec, and your acceptance criteria are almost always written in […]
