Pressure instrumentation includes various pressure gauges, transmitters, sensors, and transducers that are used to measure and display the units of the pressure of a fluid or gas.  Transducers, transmitters, and sensors measure the pressure in pumps, pipes,  tanks, and other processes and then send a signal to a display, controller, HMI, or other devices. Pressure gauges are analog or digital devices used to display the readings and provide local real-time measurements for effective pressure monitoring.
