What instrument would have a tag name of ZIT-200?

The tag name ZIT-200 suggests that it relates to a type of indicating transmitter. The designation typically includes a prefix that indicates the function of the instrument, and in this case, the "IT" in the tag represents "Indicating Transmitter." Given that this instrument is concerned with position measurement, the "Z" prefix can often refer to "Zero" or a specific type of measurement, and in many control systems, position transmitters are commonly found.

Such instruments are used to provide continuous feedback regarding the position of a valve, actuator, or similar equipment within a control system. This feedback is crucial for effective process control, ensuring that systems operate as intended by accurately reflecting physical positions for adjustments by controllers.

By acknowledging these aspects, it becomes evident why a tag name like ZIT-200 specifically refers to a Position Indicating Transmitter, while other options may not accurately represent the instrumentation and its intended function.
