The EB and EIC options are used with PDPA and LDV systems to take external data, along with measurements made using PDPA and LDV.

The EB plug-in board option allows input of up to 4 channels of analog data, including the once-per-rev (OPR) signal. The EIC module allows input of the 4 analog and OPR signals, plus up to 4 channels of digital data, all using a convenient interface box with Status Light, BNCs, and D-Sub connectors. This module is supplied with the EB plug-in board.

For external data (e.g., temperature, pressure, etc.), a four channel analog-to-digital and digital-to-digital input module in the EB board is utilized. These channels can be used to acquire peripheral data from any transducer with output in the range -5 to +10V. The FLOWSIZER™ Data Acquisition and Analysis Software allows real-time display of these auxiliary inputs, calibration using a 4th order polynomial, and analysis of velocity-scalar quantities.

The EB/EIC system does not simply tag each velocity point with an angular position for post-analysis. Instead the user defines an unlimited number of angular windows (perhaps each blade passage). The software then allows the real-time display of velocity and diameter statistics for individual windows, user-selectable angular intervals, or the whole cycle. A host of rotating machinery specific post processing options is also provided.
