Sensors & Measurement
Pressure sensor
A device that converts pressure into an electrical signal or digital value.
IN ONE SENTENCE
It tells a control system how much pressure is present.
In normal English
Different sensors measure gauge, absolute or differential pressure and use different technologies, ranges, materials and outputs.
Why would I use it?
Use it when you need a continuous pressure measurement rather than a simple switch point.
THINK OF IT LIKE…
A pressure gauge that can talk to the control system.
