The WBK18 provides 8-channels of dynamic signal input. The WBK18 provides all of the signal conditioning and biasing required for the system to accept piezoelectric accelerometers, piezoelectric pressure sensors, piezoelectric microphones, proximity sensors, or any other dynamic input source. All channels on the WBK18, and on other WBK18 modules within the same system, are sampled simultaneously to insure phase matching between channels. Each WBK18 channel features a software programmable 8-pole low-pass filter to remove undesired frequencies and alias components. Data integrity is additionally insured through overrange and IEPE fault detection mechanisms.
