The Columbia Series 5820 Charge Amplifiers are designed for use with virtually all piezoelectric transducers to form various airborne vibration and shock data acquisition systems. These devices feature a very small package size and extremely low power consumption.
The Series 5820 Charge Amplifiers provide dual signal outputs, one biased around +2.50VDC and one unbiased capacitance coupled, and are available in seven standard chare conversion ranges, each offering a 10:1 tandem gain adjustment capability. A range of seven low-pass filters are available to meet your individual vibration measurement needs.
Consult the factory for customizes versions of these sensors.
