Pressure and temperature measurement at extremely low ambient temperatures
Christopher Ott | Know-howStandard pressure gauges and thermometers generally cope with ambient temperatures down to -40 °C. But what must be the features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using …
Vibration protection: Case filling vs. dampened movement
Christopher Ott | Know-howVibrations can sometimes violently load Bourdon tube pressure gauges. They cause pointer flutter and also, in the event of sustained loading, damage to the measuring system, even to the point of total failure. The most effective protection against these effects is …
High-pressure gauges: New standard, DIN 16001, delivers safety
Christopher Ott | Know-howThe German institute for standardisation (Deutsches Institut für Normung) has opened up new territory: Its DIN 16001 is the world's first standard that deals exclusively with high-pressure gauges. In accordance with the criteria described within it, WIKA is at the …
Alarm contacts: When pressure gauges switch
Christopher Ott | Know-howMechanical pressure measuring instruments with integrated alarm contacts offer two functionalities in a single unit. The task of the pressure measurement is achieved without the need for any external power supply and thus always provides a reliable on-site display. At …
