piezo accelerometer

A piezo accelerometer works on a simple principle: a seismic mass presses on a piezoelectric crystal, and the charge output is proportional to acceleration. But getting that signal cleanly into your data acquisition system is where the engineering matters. Our designs, part of the Kingmach geotechnical and industrial monitoring portfolio, use shear-mode elements that are less sensitive to base strain and thermal transients. That means you spend less time chasing phantom vibrations. The housings are typically stainless steel, sealed against dust and moisture, and usable across the -40°C to 120°C range common in field installations. For low-frequency applications—say, seismic monitoring or structural health—we can supply charge-output models that work with external signal conditioners. For plant-wide condition monitoring, we build IEPE (ICP) versions with built-in microelectronics, so they plug directly into most vibration analyzers. Because we’re not tied to a single supply chain, we can often adapt mounting threads, connector orientations, or cable lengths without long lead times. Customers in mining, power generation, and heavy manufacturing use these sensors on crushers, gearboxes, and piping. While no two sites are alike, the feedback points to a common thread: the piezo accelerometers hold their sensitivity well over years of 24/7 operation, and when they do need replacement, our technical team helps verify the new unit matches the original profile.
