Precision Low-Noise Bridge Amplifier


The Model 121 is a state-of-the-art, 3-Channel DC Differential Amplifier designed to be used with bridge type or differential output accelerometers, pressure transducers, and load cells.  The amplifier offers an exceptionally low input noise floor of <20µVrms and wide bandwidth to 200kHz, ideal for transient measurements.  With the Model 121, the user can instantly program gain or output scaling, and activate auto-zero controls for each channel using the front panel push-buttons.  Useful features such as shunt calibration, 0 to 25Vdc programmable sensor voltage supply, and user-defined 2-pole Butterworth LP filter modules, make the Model 121 a perfect choice for your applications.
