Course Description

This introductory course on basic pressure instrumentation process measurement will provide students with a review of pressure measurement and control for processes including symbols, terminologies and technologies needed to work in the field.  Understanding a pressure loop and P&ID and basic wiring techniques will be covered along with how instruments communicate.  Students will be exposed to hands-on training utilizing pressure gauges, differential pressure transmitters, valves, and pressure drops across valves.  All transmitters are Endress Hauser and support the HART communication protocol.  The class will be a combination of classroom and hands-on training utilizing the ATN Instrumentation Mobile Training Unit with a working process with on-line instrumentation and controls.

This course requires a prerequisite:  Introduction to Instrumentation.

Course Objectives

At the end of this course, students should be able to:

  1. Describe the different methods of operation of pressure measurement.
  2. Install, setup and check pressure loops per a P&ID.
  3. Overview of common pressure elements.
  4. Know the difference between pressure gauges, gauge pressure, absolute pressure, and vacuum pressure and differential pressure.
  5. Install and use pressure switch.  
  6. Install and use pressure transmitters.
  7. Be familiar with the basic principles of operation of a typical differential pressure transmitter – setup, impulse lines and bleeding, and configuration.
  8. Use Hart 475 Communicator to configure Endress Hauser Differential Pressure Transmitters.
  9. Be familiar with a Fluke pressure calibrator.
