Temperature And Frequency Test Devices (ATI03)

This comprehensive INVOLVE?? interactive multimedia training program was produced in association with the Instrument Society of America (ISA).

This four-lesson program trains participants on the principles and procedures of various test devices.

Prerequisites

This lesson is designed for participants familiar with process control principles and instruments. An understanding of basic algebra is also recommended as well as knowledge of temperature calibrators and sweep/function generators. Emphasis is placed on equipment selection and set-up for various types of sensors.

Description

This lesson describes the features of a temperature calibrator and how calibrator temperature and sensor type are configured. This lesson also describes the reading and maintenance of thermocouplers and thermocoupler valves.

Objectives

Describe the features of a temperature calibrator and how calibrator temperature and sensor type are configured. Describe how calibrator output memories and ramp steps are configured. Demonstrate taking a reading of a thermocouple input. Demonstrate taking a reading of a 4-wire, 3-wire, and 2-wire RTD input. Demonstrate connecting the calibrator to an instrument to simulate a thermocouple. Demonstrate outputting a thermocouple value. Demonstrate the connection of the calibrator to an instrument to simulate an RTD. Demonstrate the production of an RTD value. Define the sweep/function generator as an instrumentation test instrument. Describe the switches, controls, displays, and indicators found on a sweep/function generator. Demonstrate a proper variable symmetry operation ? And demonstrate generation of frequency input for a controller.
