What device can send signals to a controller in a measurement system?

In a measurement system, a transmitter plays a crucial role in the process of signal communication. It is designed to take the signals generated by a sensor, which may detect physical phenomena (such as temperature, pressure, or flow), and then convert and transmit these signals to a controller for further processing and interpretation.

Transmitters can amplify, condition, and convert the signals into a standardized form suitable for effective communication with the controller. They ensure that the data being sent accurately reflects the measurements taken by the sensor, thus allowing the controller to make informed decisions based on reliable information. This function is essential in various applications, from industrial processes to environmental monitoring.

While sensors are responsible for detecting and measuring a physical variable, transmitters enhance the ability to communicate that information effectively over distances. They are integral components that ensure the efficiency and accuracy of measurement systems in real-time monitoring and control operations.
