New Model 101 Voltage Amplifier from Measurement Specialties works with all piezoresistive bridge-configuration sensors.
A signal conditioner that provides clean sensor power supply and output amplification for precision dynamic measurement of pressure and vibration has been introduced by Measurement Specialties. The new Model 101 three-channel DC differential voltage amplifier features DC to 200 kHz 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 ideal 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. Applications include automotive crash testing, wind tunnel testing, structural testing for seismic resistance and weighing. It also supports prototyping and calibration of medical devices
Input signals with magnitudes of ±10 Vdc can be zeroed, and a unique DAC routine allows output zero to be trimmed to within ±1m Vdc. The microprocessor controlled conditioner features 10 Vdc 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.
Measurement Specialties, Inc., designs and manufactures a wide variety of sensors and transducers to measure precise ranges of physical characteristics including pressure, force, vibration, position, humidity and temperature.
