摘要: An accelerometer (102) senses acceleration in a specific direction through the voltages produced by multiple piezoelectric sensors (114, 302, 304) electrically arranged in parallel in response to the acceleration. The main axes of sensitivity of the piezoelectric sensors are aligned and point in the same direction. The parallel arrangement enables to control the thermal noise level of the output signal of the accelerometer that originates in a bias resistor (116) connected in parallel to the parallel arrangement of the piezoelectric sensors.

摘要: A vibration and condition monitoring system with true digital signal processing based design, with very limited analog based general signal conditioning and integrated specific sensor conditioning and sensor power supply options. The device supports direct connection of eddy current probe systems to the module, due to a built-in driver and linearization functionality. Linearization and compensation of a specific eddy current probe/cable system is done by measuring its far/infinite gap response. This response is then according to the invention recalculated into a linearization curve/transfer function. Specific sensor signal conditioning is not dependent on hardware, but only on embedded software (firmware). There is full sensor input support in an I.S. environment. Not only the common sensor input types from accelerometer, velocity sensor or eddy current probe system for both vibration and/or speed measurements.
