piezoelectric vibration sensor

A piezoelectric vibration sensor turns mechanical strain into an electrical charge, and that simple principle makes it a workhorse for condition monitoring, modal analysis, and low-frequency geotechnical surveys. The performance hinges on several practical details: charge sensitivity, frequency response linearity, operating temperature range, and whether the sensor design isolates the element from base strain and thermal transients. Kingmach manufactures piezoelectric vibration sensors with compression-mode and shear-mode designs, each suited to different noise and temperature environments. Shear-mode elements typically deliver better isolation from mounting surface distortions, which matters when you’re measuring slow movements on concrete bridges or turbine housings. Compression-mode sensors offer higher charge output for a given size, useful in compact spaces where a lower noise floor is critical. We don’t force a single line of standard products. For long-term geotechnical monitoring, many projects require low-noise coaxial cables with integral charge converters, or top-entry connectors that survive pull forces in borehole deployments. On heavy rotating machinery, a side-exit armored cable and a stud-mount base often save hours of installation. Our engineers walk through the signal chain—from sensor element to data logger input—to recommend a configuration that keeps signal-to-noise ratio high and field failures low. Custom sensitivity calibration, specific low-frequency roll-off filters, and submersible housings are all part of the discussion. With inventory stocked across regional hubs and technical support teams responding within one business day, you can iterate the pilot setup quickly. Whether the job is vibration trending on a motor bearing or seismic monitoring next to a excavation, the sensor package is designed to earn its place in your data architecture.
