Noises are common in test and measurement applications. They are undesired signals that are generated by the combination of electrical and mechanical components of sensors and hardware devices. The noises present in acceleration measurement can be generated from the accelerometers, signal amplifiers or cables.
At many applications, noise can be dealt with by using a signal conditioner to filter the unwanted data before transmitting the signals to the computer. However, it can present a major problem for seismic monitoring or other specific tests that are unable to tolerate noise.
This whitepaper discusses how manufacturers have designed a low noise accelerometer to cater to such applications.
