Description
The WBK16 is an 8-channel strain-gage signal-conditioning module for the WaveBook system. Up to
eight of these modules (64 channels) can be accommodated by a WaveBook and scanned at 1 µs/channel.
Almost all bridge configurations are supported via a bridge-completion network and software. High-gain
differential-amplifier applications are also supported. Software controls bridge configuration, gain, offset,
excitation voltage, polarity, filtering, and the calibration process.
