What is the document that lists all pertinent information regarding each instrument by a tag number?

• A. Specification sheet
• B. Loop sheet
• C. Instrument index
• D. Piping drawing

Answer: (C)

The instrument index is the document that comprehensively lists all pertinent information regarding each instrument by its tag number. This document serves as a key reference for engineers and technicians, providing essential details such as instrument type, specifications, location, and ownership. By organizing this information by tag number, the index allows for easy identification and management of instruments throughout the lifecycle of a project. In the context of instrumentation and control systems, the instrument index proves vital for maintaining clarity about the devices involved in the process. It aids in inspections, maintenance, and troubleshooting, ensuring that personnel can quickly access relevant data when needed. Other documents like specification sheets, loop sheets, and piping drawings serve different purposes. Specification sheets detail the specific requirements and characteristics of individual instruments. Loop sheets describe the connections and wiring within a control loop, while piping drawings depict the physical layout of pipes, valves, and fittings but do not typically include detailed instrument information indexed by tag numbers. Each of these documents is important in its own right, but the instrument index specifically tracks instruments as outlined in the question.
