Description

You’ve learned that the sensors of ebooks 6 and 7 convert mechanical effects (vibration, shock and noise) into electrical signals. You want your final data to precisely represent a particular quantity of measurand, right? You want to trust each picocoulomb or each millivolt from your accelerometer, for example, to result from a particular magnitude of acceleration. In ebook 9 you will learn about laboratory mechanical calibration to verify that relationship. Here in ebook 8 you will learn that when you use a measurement system (sensor, signal conditioner and some readout instrument) inside or outside the lab, intending to feed the measurement system’s electrical signals to various real or virtual instruments for various purposes, you must guard against the electrical errors mentioned herein as well as the mechanical errors mentioned in ebook 7.

Be warned that an accelerometer might, without your knowledge, contain a filter, intended for some special purpose. For example, it might be intended to protect the accelerometer against very severe electrical spikes during pyro shock measurement. Another example: it might be band-limited to say 3 – 40 Hz in order to focus measurements on some equipment’s fundamental running speed. Don’t blindly use an accelerometer without checking manufacturer data on that specific model. And the records of its most recent calibration (see ebook 9).
