COURSE NO: E04-022
An Introduction to Instruments and Devices for Boiler Control Systems
Course Highlights

This online engineering PDH course provides an introduction to instruments and devices employed in boiler control systems.  Both, panel instruments as well as local devices and instruments are discussed.  Requirements are provided for controllers, recorders, totalizers, indicators, status lights, annunciators, selector switches, pushbuttons, and plant control stations.


You will learn about control valves, pressure regulators, solenoid valves, actuators, current-to-pneumatic converters, dampers, pressure relief valves, rupture disks, level instruments, flow instruments, temperature measurements, pressure measurements, electronic transmitters, electrical instrument switches, analyzers, flame detectors and continuous emission monitoring.  You will be introduced to recommended boiler control panel instrumentation as well as local boiler devices.


This 4 PDH online course is applicable to mechanical and electrical engineers and other design and construction professionals seeking to learn about devices and instruments used to control boilers and boiler plants.
