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 …
Advantages of diaphragm pressure gauges (2): High overload protection
Silvia Weber | Know-howOverload can quickly expose the limit of any pressure measuring instrument. Diaphragm pressure gauges withstand a significantly higher maximum pressure when compared to instruments with Bourdon tubes. This protection is due to their physical design. A …
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 …
