Question

Accepted Answer

Transmitter, RTD, thermocouple, control valve, and actuators are all important components in instrumentation technology.

Transmitter is a device that converts a physical parameter into an electrical signal.
RTD (Resistance Temperature Detector) is a type of temperature sensor that measures temperature by detecting changes in electrical resistance.
Thermocouple is another type of temperature sensor that measures temperature by detecting changes in voltage.
Control valve is a device that regulates the flow of fluid or gas in a system.
Actuators are devices that convert electrical or hydraulic energy into mechanical motion to control valves or other components.
