This module contains instructional materials on instrumentation to help teachers train students in the job skills they will need as beginning instrumentation technicians. The module addresses the nature of accessing, measuring, and controlling phenomena such as level, flow, pressure, and temperature. Students are introduced to the devices and formulas that make process instruments work. The module contains seven instructional units that cover the following topics: introduction to control systems; system components; principles of pressure measurement; principles of level measurement; principles of temperature measurement; principles of flow measurement; and process systems. 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. The information sheets explain elements of physics and mathematics needed to evaluate functions, and the job sheets provide guides for experiments that turn theory into a physical event. Instructional task analyses; a tools, equipment, and materials list; and 15 references are also included. (KC)
