This module provides instructional materials that are designed to help teachers train students in job skills for entry-level jobs as instrumentation technicians. This text addresses the basics of troubleshooting control loops, and the transducers, transmitters, signal conditioners, control valves, and controllers that enable process systems to work correctly. Pretesting and calibrating instruments are covered, and data charts and calibration graphs that technicians use on a routine basis are provided. The module contains seven instructional units that cover the following topics: principles of pneumatics; calibration standards and test equipment; transducers and transmitters; signal conditioning; actuators, positioners, and control valves; controllers and controller tuning; and interactive loops (boilers, distillation towers, batch processes). Each instructional unit follows a standard format that includes some or all of these eight basic components: performance objectives, suggested activities for teachers and students, information sheets, assignment sheets, job sheets, visual aids, tests, answers to tests, and assignment sheets. Instructional task analyses; a tools, equipment, and materials list; and 21 references are included. (KC)
