Instruments used in electrical and instrumentation engineering include sensors, transmitters, controllers, and recorders.

• Sensors: devices that detect changes in physical properties and convert them into electrical signals (e.g. temperature sensors)

• Transmitters: devices that send signals from sensors to control systems (e.g. pressure transmitters)

• Controllers: devices that regulate the operation of systems based on input...read more

Control valves are used to regulate the flow of fluids in a system by varying the size of the flow passage.

• Types of control valves include globe valves, butterfly valves, ball valves, and diaphragm valves.

• Control valves can be classified based on their action (linear or rotary), flow characteristics (equal percentage, linear, or quick opening), and body type (single-seated, double-seated, or cage).
