ANALOG VS DISCRETE SIGNALS
Analog Instruments: Provide continuous measurements and can represent a range of values. They are used to monitor variables where precise readings are required, such as Pressure, Temperature, Level, Flow, and Conductivity.
Discrete Instruments: With their binary (on/off) status indicators, discrete instruments are reliable tools often used for detecting specific conditions. They are employed where the presence or absence of a condition needs to be monitored, such as High-Level Detection, Flow Switches, High-Pressure Indicators, and Proximity Sensors.
