Temperature is the most commonly measured physical quantity. Thermometry, the measurement of temperature, involves a wide range of technologies. Its uses range from maintaining a comfortable and safe environment for people to industrial processes operating at over 3,000 °C and quantum computing operating at near absolute zero. This article reviews some of the more common […]

FAQ on railroad hot-box-temperature sensing: part 2
Modern electronics should be able to easily solve a temperature-sensing challenge, but the harsh real-world complexities make it a difficult proposition. Part 1 of this article looked at the basic issues of railway bearing failure and detecting these before they happen. This part looks into more details and sensing options. Q: What can the railroad […]
What’s the difference between 2-, 3-, & 4-wire RDT sensing?
The difference is measurement accuracy. Using 2-wire resistance temperature detector (RTD) sensing provides good accuracy (maybe), the accuracy of 3-wire sensing is better, and 4-wire sensing provides the best accuracy. In addition, there’s the option of using Wheatstone bridge topologies to improve the performance of 2- and 3-wire RDTs. This FAQ begins with a review […]

How can the new temperature-sensitive COVID-19 vaccines’ temperatures be ensured?
The newly developed COVID-19 vaccines require low temperature storage to ensure their efficacy. For the Pfizer-BioNTech vaccine, the U.S. Centers for Disease Control and Prevention (CDC) specifically states that it should be stored in an ultra-cold freezer, thermal shipping container or refrigerator. The ultra-cold freezer’s temperature should be maintained between -80°C and -60°C (-112°F and […]

How can sensors ensure safety for extreme temperature requirements?
The medical device industry requires extreme high temperatures in autoclaves to disinfect reusable devices and tools. As we have been reminded of recently with announcement of COVID-19 antibiotics, medicines as well as bio-samples require low temperatures for preservation in storage and transportation. Both of these extremes require sensors to monitor and maintain the proper temperature […]
