Model 101 voltage amplifier

The Model 101 three-channel DC differential voltage amplifier features DC to 200kHz bandwidth for fast response. Its discrete channels provide clean sensor power supply (0-12 Vdc) and output magnification (0-999 gain) for three sensors simultaneously. The amplifier is suitable for vibration, shock testing, process monitoring and other common tests performed by instrumentation laboratories. It is designed to work with any piezoresistive bridge-configuration transducer such as accelerometers, vibration and pressure sensors, force sensors and load cells. Input signals with magnitudes of ±10VDC can be zeroed, and a DAC routine allows output zero to be trimmed to within ±1m VDC. The microprocessor controlled conditioner features 10VDC peak linear output and 0.5% FS output accuracy. It provides multi-sensor support, variable gain adjustment, shunt calibration capability and multiple excitation level settings. A wide selection of optional frequency roll-off filters is available.
