A signal-conditioning circuit must have very low input impedance to collect most of the charge output by the sensor. Measurement Specialties’ new Model 4610 accelerometer with on-board signal conditioning is designed for low level accelerations for instrumentation test, aerospace and automotive applications. Thus, the charge amplifier is the ideal solution since its input presents a virtual ground to the sensor signal as long as the amplifier maintains high gain at those signal frequencies. Signal conditioning needs vary widely in functionality depending on your sensor, so no instrument can provide all types of conditioning for all sensors. Similar to the sensitivity specification, frequency response also tells you what the accelerometer’s scale factor is, but with the additional variable of frequency added.
