Course Outline
This 4-hour course
utilizes US Department of Energy training materials (DOE-HDBK-1013/1-92, INSTRUMENTATION
AND CONTROLS, Vol. 1, Modules 1 through 4) to instill a fundamental understanding
of various instrumentation and control detection circuits as they relate to
temperature, pressure, flow, and level monitoring of various processes.
This course includes
a True-False quiz at the end, which is designed to enhance the understanding
of the course materials.

- Describe the purpose, function, and components of a bridge circuit.
After studying Module 2- Pressure Detectors, the student will:
- Explain how bellows and bourdon tube-type pressure detectors work including method of detection and method of signal generation.
- State (3) environmental concerns that can affect the accuracy and reliability of pressure detection instrumentation.
- Describe the
basic function and operation of a strain gage pressure detector including
method of detection and method of signal generation.
After studying Module 3- Level Detectors, the student will:
- Explain the principal of operation for various types of level detectors including gauge glass, magnetic bond, conductivity probe, ball float, and differential pressure level detectors.
- Explain the process of density compensation.
- State (3) environmental
concerns that can affect the accuracy and reliability of level detection instrumentation.
After studying Module 4- Flow Detectors, the student will:
- Explain the principal of operation for various types of flow detectors including orifice plates, Venturi tubes, Dall flow tube, Rotameter, Nutating disk, and Pitot tubes.
- Describe the process of density compensation for a steam flow instrument including the reason density compensation is required and the parameters used.
- State (3) environmental
concerns that can affect the accuracy and reliability of level detection instrumentation.
Course Introduction
In almost any nuclear,
chemical, or mechanical system, the temperature, pressure, flow, and level of
fluids through a piping system or process must be closely monitored and controlled.
Various types of temperature, pressure, level, and flow detection circuits accomplish
this task. A basic understanding of the theory, characteristics, and mechanical
components of various temperature, pressure, level, and flow controls and instrumentation
is essential to understanding how they function and operate within a system
or process.

Summary
Controls and Instrumentation
are utilized as a primary means of monitoring and controlling fluid temperature,
pressure, level and flow in various systems and processes and find applications
in nuclear, chemical, and mechanical systems. Engineers involved in the application,
and selection of various instrumentation and control systems require a fundamental
understanding of the application, operational characteristics, and components
of various types of temperature, pressure, level, and flow control detection
circuits. The following course will provide the fundamental framework for this
knowledge.
