How do digital pressure gauges fundamentally differ from Bourdon mechanical gauges in terms of output?

Answer

Digital gauges rely on electronic transducers converting changes into an electrical signal for numerical display.

Mechanical gauges provide a direct reading through physical linkage to a needle, whereas digital gauges rely on electronic transducers that convert physical changes into an electrical signal which is then processed and displayed numerically.
