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 …
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 …
Safety temperature limiter for plants safe to operate
Andreas Borchard | Know-howHeat-generating plants are used in industry and in heating technology. The safe operation of such plants requires a large number of safety devices. They are designed to prevent, among other things, excess temperature, overpressure and vacuum. In the area of temperature …
