Four Aurora high school students are playing an important part in the development of the COVID-19 vaccine storage system. The students are volunteering their time to make part of a crucial sensor used to transport the vaccine. “I was really interested and excited for it because it sounded like an interesting volunteering opportunity,” said Aiden…
“An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. “The relationship between an RTD’s resistance and the surrounding temperature is highly predictable, allowing for accurate and consistent temperature measurement. By supplying an RTD with a constant current and measuring the resulting…
“The height of the column is divided up and marked to correlate it with known temperatures, for example: at water boils 100°C (212°F), and it freezes as 0°C (32°F). As the liquids volume expands and contracts, we can easily read the temperature. “This method is easy for humans to use but it’s slow, it’s not…
New to RTDs? Consider this. According to Knowledge.Ni.Com: RTD Overview “A platinum resistance temperature detector (RTD) is a device with a typical resistance of 100 Ω at 0 °C. It consists of a thin film of platinum on a plastic film. Its resistance varies with temperature and it can typically measure temperatures up to 850…
