Which 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 …

EAC approval for pressure gauges and thermometers: What must be considered?
Jürgen Reiser | Know-howWhoever exports measuring instruments or other technical goods to Russia and many of its neighbouring countries, has to go through the certification process of the “Eurasian Conformity” (EAC). An EAC approval is comparable with CE conformity. It is issued for each …
Operation of a temperature dry-well calibrator
Matthias Bundschuh | CalibrationDry-well calibrators are portable instruments for the simple on-site calibration of temperature measuring instruments. A temperature dry-well calibrator consists of an electrically heated or cooled metal block, an accurate temperature control and an internal reference …
Selection criteria for mechanical Thermometers (1): Response time
Christoph Strebel | Know-howSelecting suitable mechanical thermometers for a process is not a quick task. Bimetal thermometers or gas-actuated thermometers - the decision on the type of thermometer alone depends on several factors. One of the most important selection criteria is the response time …
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 …
