What does the I to P (I/P) converter do?

The function of an I to P (I/P) converter is to convert electronic analog signals into pneumatic signals. In process control, I/P converters play a crucial role in translating control signals from electronic devices, such as a digital controller, into pneumatic output that can be used to operate instruments like control valves and actuators. This conversion enables effective control of processes using pneumatic systems, allowing for greater precision and reliability in operations.

The other options do not accurately describe the I/P converter’s function. While the I/P converter specifically converts electrical signals for use in pneumatic systems, measuring flow velocity or indicating pressure are tasks typically managed by other types of instruments, not an I/P converter. Thus, the correct understanding of the I/P converter’s role is essential for effective instrumentation and control in industrial settings.
