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 …
Pt100 in 2-, 3- or 4-wire connection?
Roland Sachs | Know-howPt100, Pt1000 and NTC are the most-used measuring elements in resistance thermometers . I would like to use this blog to consider the question of connection types in greater detail. Resistance thermometers change their electrical resistance as a function of …
Pt100, Pt1000 or NTC – which is the right sensor?
Roland Sachs | Know-howEspecially the machine-building industry often asks me which is the right measuring element for them. This is the reason why I want to explain in this article the differences between the most commonly used sensors Pt100, Pt1000 and NTC. I will go into more detail about …
