### Operating conditions

| Max. process temperature, process pressure | Depending on: ■ Load diagram DIN 43772 ■ Thermowell design - Dimensions - Material ■ Process conditions - Flow rate - Medium density |
|---|---|
| Wake frequency calculation (option) | The calculation in accordance with Dittrich/Klotter or ASME PTC 19.3 TW-2016 of individual thermowells minimises the risk of dynamic damage that can be caused by the vortex shedding of a Kármán vortex street (Vortex Induced Vibration; VIV). In addition, the static loads due to lateral flow and the process pressure are calculated depending on the temperature.The calculation will be carried out as aWIKA engineered service (subject to charges). |
