A brief guide to selecting VC and PR accelerometers

摘要

With the advent of variable-ca-pacitance (VC) accelerometers and the continued availability of piezoresistive (PR) transducers, engineers now have a wider choice for their measurement needs. But VC devices seem to garner comments such as: "They are the same as PRs, so why change?" or "They are different and hard to understand, so I'm going to stick to what I know." Therefore, a closer look at the relative merits of these technologies seems in order.
