Strain Gauge Amplifier
Logic Interface Board

This device is a high precision, rack mount, 16 channel, USB-based strain gauge measurement and data logging system. The system features programmable DSP-based filtering of the strain gauge signal so that any customer-defined filter can be implemented.


Other features include a programmable strain gauge excitation voltage of 5V, 10V, or 20V with extremely small excitation ripple, and can accommodate any strain gauge between 350 and 2000 Ohms. The amplifier gain can be varied between 1 and 10000 in 1:2:5 step increments with the resulting noise being less than 20mVp-p at max gain of 10000. Any offset inherent to the strain gauge can be zeroed using coarse and fine offset adjustment controls.

BNC outputs of the pre-filtered signal allow for external signal filtering and an optional external sample rate clock can be injected for synchronization with other subsystems. The system employs industry standard XLR connectors for the strain gauge interface.
