A Bellows-type sensor responds to a change in which variable?

Bellows-type sensors detect changes in pressure. The flexible bellows expand or contract in response to a pressure difference, and that mechanical movement is translated into a readable signal. Temperature or humidity can affect materials but are not the primary quantity being measured, and flow is typically inferred from pressure changes elsewhere rather than from the bellows itself. So the variable being sensed is pressure.
