DirectDrive pressure gauges differ in structure and function from standard pressure gauges. Thus they feature special characteristics that qualify them for specific application areas. In DirectDrive pressure gauges, special pressure elements are fitted, which …
Vibration/shock
Filling liquids in pressure gauges: Usage and advantages
| Sandra Broßler | Pressure, ProductsLiquid-filled pressure gauges are used in applications that involve high dynamic shock and vibration loading. The filling liquid dampens the vibrations that occur and thus takes the load off the mechanical components of the pressure gauge. Depending on the operating …
New ScrutonWell ® design for thermowells
| Kai Grabenauer | TemperatureIn order to avoid any damage to the thermowell during operation due to mechanical loads, a thermowell calculation per ASME PTC 19.3 TW-2016 is recommended for critical process conditions. In case of a calculation with negative results, the only constructive solution so …
Shock resistance of pressure sensors
| Matthias Stratmann | Know-howIn many pressure sensor applications, short-duration, high, impact loading occurs - this is referred to as shock. Shock resistance defines up to what level of acceleration the instrument can withstand the shock loading without being damaged in any way. The loading …
Which vibrations are pressure transmitters subjected to in the laboratory?
| Matthias Stratmann | Know-howBasically, there are three common vibration tests with which the leading manufacturers test their instruments; with fixed and sweeping frequency (IEC 60068-2-6) and a broadband random pattern (IEC 60068-6-64). In the first test, the pressure transmitter is subjected to …
