This lesson describes
the instrumentation techniques and equipment used to measure, indicate and
manipulate the basic process parameters in a typical industrial control environment. This PDF book covers
the following topics related to Process Instrumentation : Introduction to
Instrumentation Equipment, ISA Symbols, Pressure Instrumentation, Level
Instrumentation, Flow Instrumentation, Temperature Instrumentation, Control
Valves and Accessories.
The contents in these notes are as follows : Instrumentation, Basic
Concepts of Process Control, Linear Closed Loop Systems, Stability Analysis,
Control Valves and Advanced control systems.

Sensors to measure process
conditions and valves to influence process operations are essential for all
aspects of engineering practice.Engineers
want to design and operate processes that remain in safe conditions, produce the
desired amounts of high quality products and are profitable.Therefore,
engineers must provide measuring devices for key variables and valves (or other
devices, such as variable speed electric motors) to influence of “steer” the
process.This site provides educational material on sensors and valves for use in the process
industries.
