Ice cold – Electrical thermometers in low ambient temperatures
Joachim Brückner | Know-howMedium temperatures of -60 °C don't even make the designers of electrical thermometers shrug their shoulders – but when one speaks of ambient temperatures of -60 °C, then one often hears a sharp intake of (cold) breath. It quickly becomes clear that one cannot …
Mineral-insulated cables – a core component for the construction of electrical thermometers
Jochen Gries | Know-howMineral-insulated cable, often also abbreviated to MI cable, consists of a metal sheath and ceramic-insulated internal conductors. The ceramic is a metal oxide powder (standard material is MgO) with a purity of > 99.0%, which ensures the insulation of the internal …
Selection criteria for dial thermometers (2): process temperature
Christoph Strebel | Know-howWhich dial thermometer is suitable for which process? Whether a bimetal or a gas-actuated thermometer is used depends on several factors - for example, on the process temperature. Bimetal thermometers are generally designed for scale ranges of -70 °C to +600 …
