Designing a Thermocouple Temperature Measurement Circuit Part 2

In this series we look at how to design a Thermocouple temperature measurement circuit. In part 2 we look at a real world example of a Thermocouple J Type circuit design and discuss some of the common sources of error and how to avoid them.

Designing a Thermocouple Temperature Measurement Circuit Part 1

In this series we look at how to design a Thermocouple temperature measurement circuit. In part 1 we look at Thermocouple theory, pros and cons versus other temperature measurement techniques, and an overview of a measurement hardware circuit as well as calculations done in software.

How to Calculate the Thermal Range of a Linear Regulator

In this video we look at how to determine whether an IC is going to work in a design from a thermal standpoint or is it going to get too hot and break / burn up. In the video we look at the popular LM317 Linear Regulator as an example.
