The term that best describes a component that selects signals based on measurement is the controller. A controller is responsible for interpreting data from various sensors and making decisions based on that data to manage system operations. It processes the information received from transducers or other measurement devices and converts it into actionable commands to control other devices within a system.

In this context, the controller serves as a critical link between measurement and action, allowing for automated responses to changing conditions. It might select signals by analyzing the measurements and determining whether to take corrective actions based on predetermined parameters.

While other options like actuator, transducer, and transmitter play important roles in the system, they do not primarily function as signal selectors based on measurement. Actuators execute control commands, transducers convert energy from one form to another (typically from measurable signals to electrical signals), and transmitters send data from one point to another but do not interpret or select signals based on measurements. Thus, the controller is the most appropriate term for a component that selects signals based on measurement.
