Big book temperature guide
"The Engineer's Guide to Industrial Temperature Measurement" is reported to be the go-to guide for reducing costs and improving performance. Its website states, "The Engineer’s Guide to Industrial Temperature Measurement will ensure you have the understanding you need to select the right measurement system. It will also show you how to install components correctly and maintain the system. The guide provides insight beyond sensors, transmitters and thermowells, offering technical information on the entire temperature measurement system." It includes FAQs, temperature measurement basics, engineering and design, maintenance and calibration, best practices and reference materials. It's available free-of-charge, but registration is required.
Regulators 101 video
This 41-minute video, "Regulators 101: Basics of Pressure and Temperature Regulators," delivers a thorough examination of available technologies and their functions. It's presented by Jordan Valve's project manager, Harry Woebkenberg, who discusses the basics of industrial pressure and temperature regulators. Topics covered include: the regulator–a proportional controller; what to expect from a regulator; keys to proper regulator sizing; pressure-reducing valves; back-pressure-reducing valves; and temperature regulators.
Temperature control page
"Temperature Process Controllers" webpage at Omega Engineering's well-known website provides an introduction to many temperature control concepts, technologies and products, and includes links to many related resources. It includes FAQs and advice on evaluating and selecting the right temperature controller.
Differential pressure basic
This short, five-minute video, "The Differential Pressure Flow Measuring Principle (Orifice-Nozzle-Venturi)," by Endress+Hauser, provides a good introduction to many of the pressure principles involved in flow measurement.
In just under three minutes, this video, "Pressure and Temperature Control-Basic Applications," touches on the main concepts related to pressure and temperature measurement in the process control and automation field. It's presented by Danfoss Industrial Automation.
"Temperature Controller Basics Handbook" webpage provides a short introduction to the reasons why temperature controllers are needed, how they work, common applications, functional components and types, and other controller characteristics. It's presented courtesy of Danaher's Industrial Controls Group and its Process Automation, Measurement and Sensing division.
Cool temperature booklet
This 49-page PDF provides a nice introduction to the basic concepts of temperature measurement and most of the various technologies used to perform it. It also contains a variety of useful charts and references, and is hosted and presumably produced by Missouri University of Science and Technology.

Pressure, temperature lectures
These two one-hour videos, "Lecture 4—Temperature Measurement" and "Lecture 5—Pressure, Force and Torque Sensors," present many of the concepts essential to both technical fields. Subtitles are included to fill in any gaps in understanding the audio. The videos are part of an overall series on Industrial Automation and Control by Prof. S. Mukhopadhyay, Department of Electrical Engineering, IIT Kharagpur.
