A signal conditioner that provides clean sensor power supply and output amplification for precision dynamic measurement of pressure and vibration has been introduced by 2205 Measurement Specialties. The new Model 101 three-channel DC differential voltage amplifier features DC to 200kHz bandwidth for fast response. Its discrete channels provide clean sensor power supply (0-12Vdc) and output magnification (0-999 gain) for three sensors simultaneously.
According to Measurement Specialties, the amplifier 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.
Input signals with magnitudes of ±10Vdc can be zeroed, and a unique DAC routine allows output zero to be trimmed to within ±1mVdc. The microprocessor controlled conditioner features 10Vdc peak linear output and 0.5 per cent 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.
