What technology allowed for continuous, precise monitoring of pressure via an electrical signal?
Answer
The modern pressure sensor
The ability to achieve accurate, real-time pressure monitoring developed separately within industrial and scientific contexts, leading to the creation of the modern pressure sensor. Unlike previous passive mechanical systems, these electronic devices were designed to convert the physical force of pressure directly into a measurable electrical signal. This capability represented a significant leap forward from simple fixed-weight valves because it allowed for continuous data acquisition and dynamic feedback, which was necessary for sophisticated instrumentation long before it was integrated into home cookware.
