Previous articles in this series described how thermocouple wire size [1] and thermocouple attachment method [2] can affect steady state temperature measurements. This article briefly discusses how these factors can affect the transient response of thermocouples when used to monitor temperatures that change value over time. Bare Thermocouple Junction Before addressing … [Read more...]
Tech Brief: Thermocouple Attachment
The previous article in this series on thermocouples described how the size of the thermocouple wire could affect its accuracy [1]. This is particularly true if the wire is exposed to high convection coefficients. This article addresses a separate issue, namely the degree to which the attachment method impacts thermocouple readings. As it turns out, once again the … [Read more...]
Tech Brief: Effect of Thermocouple Size
Thermocouples are widely used for temperature measurements. They are particularly useful in lab testing, due to their relatively low cost and the ability to easily fabricate thermocouples of specific lengths for a given test. This Tech Brief discusses issues related to the size of a thermocouple that may be considered when using them. A thermocouple consists of two wires made … [Read more...]
Summary of the IEEE ITherm 2023 Conference
The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the JW Marriott Grande Lakes, Orlando, FL, May 30 – June 2, 2023. This was the 22nd ITherm, which was first held in 1988. The conference was historically held every other year until 2016 when it switched to an annual schedule. ITherm 2023 was sponsored by the … [Read more...]
Calculating Thermal Design Power for Mobile Consumer Electronics – Part 1
Thermal Design Power (TDP) is a term commonly used in the thermal management of consumer electronics. While the usage of this terminology may vary across the industry, it commonly refers to the amount of power that a device may dissipate indefinitely, in a given thermal environment, without exceeding the temperature limits of the device. The TDP for a consumer electronics … [Read more...]
