MiniAmp
The MiniAmp is a precision six channel strain gage amplifier
ideally suited to interface with AMTI’s multi-axis force transducers and
multi-axis force platforms. The
amplifier features user selectable gains from 1000 to 4000, user selectable
bridge excitation voltages from 2.5 to 10 volts and antialiasing filters
factory set with a corner frequency of 1000 Hz.
The MiniAmp is a popular economical solution for signal conditioning and
amplification for AMTI’s multi-axis transducers and platforms.
