Differential pressure measurement is widely used as a method for monitoring the level of closed vessels. In many cases, operators use individual instruments with an output signal or on-site display. In contrast, a more precise and fault-immune solution is the measuring …
Process connection
DIN 3852-E or DIN EN ISO 1179-2?
| Sabine Mai | Know-howThe DIN 3852-E pressure connection thread standard has been invalid since 2012. The standard that has been valid since then for pipe threads (e.g. for G ¼ A) is DIN EN ISO 1179-2: “Connections for general use and fluid power - Ports and stud ends with ISO 228-1 …
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 …
Maximum pressure for pressure connection G 1/8 and 1/8 NPT
| Michèle Beyer | Know-howWhy are the threads G 1/8 and 1/8 NPT offered for pressures only to a nominal pressure range of 400 bar? Where does this limit come from? Basically, the explanation is very simple: From a certain pressure limit, the thread flanks are no longer "strong" enough to …
Differences between G1/4″ threads
| Michèle Beyer | Know-howWhat is the difference between the numerous G 1/4" threads? And are they compatible among one another? One of my colleagues also often has troubles and gets confused because of all the various G 1/4" threads which the market has to offer, or which are requested by the …
