Resistance thermometers, also called resistance temperature detectors ... carbon resistors are used at ultra-low temperatures (−273 °C to −173 °C). ...
As a thermometer for low-temperature measurements of the order of 10 K. As an inrush current limiter device in power supply circuits, they present a higher resistance initially, which prevents large currents from flowing at turn-on, and then heat up and become much lower resistance to allow higher current flow during normal operation.
A cryometer is a thermometer used to measure very low temperatures of objects. Ethanol-filled thermometers are used in preference to mercury for meteorological measurements and can measure temperatures in the range of −38 to 70 °C (−36 to 158 °F). Their main physical limitation is the freezing and boiling point of the liquid used.
It is used for making low cost resistance temperature sensors. It consists of 70% nickel and 30% iron. Balco is Carpenter Technology Corporation's brand name for this alloy consisting of 70% nickel and 30% iron. It is also sold by Harrison as "Hytemco". Its principal use is for resistance thermometers (resistance temperature detectors). These ...
Thermocouple characteristics at low temperatures. The AuFe-based thermocouple shows a steady sensitivity down to low temperatures, whereas conventional types soon flatten out and lose sensitivity at low temperature. In these thermocouples (chromel–gold/iron alloy), the negative wire is gold with a small fraction (0.03–0.15 atom percent) of ...
