Course Description

This introductory course on instrumentation will provide students with a review of process instrumentation including symbols, terminologies and technologies needed to work in the field.  The course will explore the common terms and types of drawings used in instrumentation. Students will be exposed to common definitions, signals, P&ID’s, loop sheets, basic types of instruments and the basics of control loops.  Understanding a loop and P&ID and basic wiring techniques will be covered along with how instruments communicate.  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. All transmitters are Endress Hauser and support the HART communication protocol. This course includes HART communications basics.  

This course will serve as a prerequisite for the following courses:
Temperature, Pressure, Level and Flow
