Amplifiers for Shock

Analog Signal Conditioning for Shock Measurements

Precision Filters’ suite of conditioning cards for shock measurement provides solutions for strain and bridge sensors (28144), charge and IEPE accelerometers (28304) and low-level voltage inputs (28608B).

All three cards feature high slew rate, wide bandwidth and sharp programmable filtering. Gain is distributed before and after the filter, allowing the user to attenuate the resonant frequency of the sensor prior to amplification of the in-band signal, optimizing signal-to-noise ratio for pyroshock measurements. Equipped with Precision’s FLAT/PULSE filter technology, these amplifiers provide outstanding response for applications in either the time domain or the frequency domain.
