Mineral-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 …
Heat dissipation
Joachim Brückner | Know-how"At best, a thermometer only ever measures its own temperature". The aim is therefore to equalise the temperature of the sensor element to that of the medium to be measured. Only then will the thermometer display the actual medium temperature. The heat …
