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 in each module. In addition to the support for common eddy current probe systems, employing an external driver, the module also supports direct connection of an eddy current probe system to the module, due to a built-in driver and linearization functionality. 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, but also direct input for eddy current probe systems for both vibration and/or speed measurements. The module also comprises means to assess the type and correct functionality of an attached eddy current probe system (302, 303) by means of a frequency measurement and possibly an amplitude measurement. |
