The ADcmXL1021-1 is a complete vibration sensing system that combines high performance vibration sensing (using a microelectromechanical systems (MEMS) accelerometer) with a variety of signal processing functions to simplify the development of smart sensor nodes in condition-based monitoring (CBM) systems. The typical ultralow noise density (26 μg/√Hz) in the MEMS accelerometers supports excellent resolution. The wide bandwidth (dc to 10 kHz within 3 dB flatness) enables tracking of key vibration signatures on many machine platforms.
The signal processing includes high speed data sampling (220 kSPS), 4096 time sample record lengths, filtering, windowing, fast Fourier transform (FFT), user configurable spectral or time statistic alarms, and error flags. The serial peripheral interface (SPI) provides access to a register structure that contains the vibration data and a wide range of user configurable functions.
The ADcmXL1021-1 is available in a 23.7 mm × 27.0 mm × 12.4 mm aluminum package with four mounting flanges to support installation with standard machine screws. This lightweight package (13 g) provides consistent mechanical coupling to the core sensors over a broad frequency range. The electrical interface is through a 14-lead connector on a 36 mm flexible cable, which enables a wide range of location and orientation options for system mating connectors.
The ADcmXL1021-1 requires only a single, 3.3 V power supply and supports an operating temperature range of −40°C to +105°C.
Multifunction pin names may be referenced by their relevant function only.
