The 540B is a miniature, low cost vibration sensor especially designed for embedded condition monitoring. With the lasted piezo-electrical (PE) technology incorporated in the sensor, 540B vibration sensors provide superior signal-to-noise ratio and frequency response than the other technology devices. The annular shear PE structure delivers the super stable output, ultralow noise density over an extended frequency range, which is optimized for industrial machine monitoring. 540B have typical noise densities of 8 µg/√Hz with 60µA current consumption. All series products have stable and repeatable sensitivity output which is immune to external shocks up to 5000g. 540B offer diversity mounting configuration for embedded applications. With wide range of voltage excitation from 3 to 30 Vdc, 540B also enable wireless sensing and plug-in product design. 540B are available in a 10mm × 10mm × 5.5mm SMD package, and are rated for operation over −55°C to +150°C temperature range.
