This tri-axial piezoelectric accelerometer is designed for vibration measurement in three orthogonal axes. It consists of a sensing element operating in shear mode, a semiconductor temperature sensor, and the necessary front-end signal conditioning, data acquisition, data processing and Intellibus compliant digital bus.
It is packaged in a small, low-profile metal case with two pig-tail connectors for daisy chaining the Intellibus based network. Its low noise front end signal conditioning and programmable gain allows for measurement of a wide range of vibration & acceleration levels.
Temperature readings from its built in sensor may be used for on or off-board temperature correction. There are two software selectable 3-pole anti-aliasing filters, one with a cut-off frequency at 2 KHz and another at 360 Hz in this triaxial piezoelectric accelerometer.
The 16-bit A/D converter samples data at a programmable rate up to 250 Ksps. A powerful processor performs digital signal processing algorithms such as digital filter, etc. The Transducer Electronic Data Sheet stored in non-volatile memory provides the information needed to set up the highly versatile signal conditioner and data acquisition parameters.
