Introduces physical and chemical variables and the various instruments used to sense, measure, transmit, and control these variables. Introduces control loops and their components including controllers, regulators, sensors, and final control elements. Students will discuss how to create instrumentation drawings and diagrams when developing and analyzing control loops.

- Demonstrate an understanding of control loops and their elements along with the various signals that can be transmitted through different types of control.*
- Describe the control loop elements that sense, measure, convert, and transmit process variable information.*
- Identify five of the different types of controllers used in the process industry (local, remote, split range, cascade/remote setpoint, and ratio); describe their components and function.*
- Describe major components of a control valve and how the valve operates.
- Identify symbols in process diagrams that represent equipment, instrumentation, and lines.*
- Demonstrate an understanding of instrumentation troubleshooting, including communication, calibration, proper tool use, safety, and environmental guidelines.*
Assessment and Requirements
Methods for measuring achievement of objectives:
Tests will be given throughout the semester.
- Tests scores represent 50% of the course grade.
- Laboratory activities and performance exercises will be done where students will demonstrate an understanding of practical applications. These will make up 25% of the course grade.
- A written final exam will be given which will represent 25% of the course grade.
Texts, handouts, and/or workbooks will be determined by the TAE Department.
Credit for Prior College-Level Learning
Portfolio must contain evidence that illustrates competency in all course learning objectives. Department faculty will evaluate submitted portfolios based on the evaluation rubric. Evaluation rubric and student checklist located in the Industrial Technology office.
