摘要:
Pressure transducers are everywhere, but do you know what's inside? Choosing the right technology can be critical, especially in extreme applications. Back in the days of mechanical, analog pressure gages, most designs were variations on one basic approach. However with the shift to electronic sensors, a whole new group of measuring technologies emerged. Should you pay attention to the sensor design? Is that instrument magnetic? Capacitive? Stressing a strain gage or crushing a crystal? How much do you need to be concerned? For most garden-variety applications, any approach will likely do an adequate job. However if you want truly optimal performance, or when more extreme conditions enter into the discussion, some do not perform as well as others.
