Metal bellows have long been a key component in demanding sensing and sealing applications. In fact, due to their ubiquity, many engineers now consider them generic items—just specify a few key dimensions, pick a metal alloy, and you are good to go. Think of bellows as a combination of a piston and a spring. Like a piston, bellows can convert changes in their internal or external pressure into an applied force. Like a spring, bellows deflect elastically in response to an applied force and exert a reactive force...
