Create a clear, practical introduction to pressure measurement for students in PTEC 110 Process Instrumentation at Bellingham Technical College. The audience is beginning process-technology students preparing for operator careers in refineries, water and wastewater plants, manufacturing, and other process industries. After viewing the presentation, students should be able to: Explain pressure as force per unit area. Explain how liquid height and specific gravity affect hydrostatic pressure. Distinguish gauge, absolute, vacuum, and differential pressure. Recognize common pressure units, including psig, psia, inches of water column, and inches of mercury. Identify manometers, Bourdon-tube gauges, diaphragm instruments, differential-pressure instruments, and pressure transmitters. Explain how a pressure transmitter converts a process measurement into a 4–20 mA signal. Recognize basic operator concerns involving impulse lines, instrument isolation, overpressure protection, and incorrect readings. Create approximately 15 slides for an eight-minute instructor-narrated presentation. Use plain language, real industrial examples, and the strongest diagrams and equipment photographs from the provided source material. Keep the focus on what a process operator needs to understand. Do not include detailed lab procedures, gauge calibration steps, controller tuning, pressure-regulator theory, advanced manifold alignment, or formal troubleshooting. Those topics will be covered in later course modules and lab competencies. End with a short operator-focused summary connecting the process pressure, sensing element, transmitter, displayed reading, and 4–20 mA signal. Do not create a separate “Thank You” slide.
