Outline a basic preventive maintenance plan for process instrumentation.

• A. Regular calibration checks, visual inspections, leak checks, verify wiring and tagging, update drawings, monitor for drift, replace worn parts, and document results
• B. Replacing components on a fixed date regardless of condition
• C. Only cleaning exterior surfaces
• D. Increasing sampling rate without checks

Answer: (A)

Preventive maintenance for process instrumentation centers on keeping sensors and instrument systems accurate and available through planned, condition-informed activities. Regular calibration checks ensure measurement accuracy and help catch drift before it impacts the process. Visual inspections catch signs of wear, corrosion, or physical damage that could trigger failures or unsafe conditions. Leak checks are crucial for instruments that handle fluids or gases, preventing safety hazards and process disturbances. Verifying wiring and tagging maintains correct connections and clear identification, reducing the risk of misinterpretation or miswiring. Keeping drawings and wiring diagrams updated ensures maintenance relies on current configurations, locations, and interconnections. Monitoring for drift over time helps determine when recalibration or component replacement is needed, sustaining long-term accuracy. Replacing worn parts before they fail minimizes unplanned downtime and maintains process integrity. Documenting results builds a traceable maintenance history for audits and continuous improvement. Other approaches fall short of a comprehensive preventive plan: replacing components on a fixed date ignores actual condition; focusing only on exterior cleaning neglects accuracy, safety, and wiring integrity; increasing sampling rate without checks can generate data without addressing instrument health.
