General test and measurement
The 540A is a miniature, high performance vibration sensor especially designed for embedded condition monitoring. With the lasted piezo-electrical (PE) technology incorporated in the sensor, 540A 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, ultra-low noise density over an extended frequency range, which is optimized for industrial machine monitoring. 540A have typical noise densities of 4 µg/√Hz with 0.6mA current consumption. 540A can be configured into IEPE output accelerometer with few additional components. All series products have stable and repeatable sensitivity output which is immune to external shocks up to 5000g. 540A offer diversity mounting configuration for embedded applications. With wide range of voltage excitation from 3 to 30 Vdc, 540A also enable wireless sensing and plug-in product design. 540A are available in a 10mm × 10mm × 5.5mm SMD package, and are rated for operation over −55°C to +150°C temperature range
