### Operating conditions

| Max. process temperature, process pressure | Depending on: ■ Load diagram DIN 43772 ■ Protection tube design - Dimensions - Material - Coating ■ Process conditions - Flow rate - Density of medium |
|---|---|
| Wake frequency calculation (option) | The calculation in accordance with 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 can be carried out independently using an online tool or as a WIKA engineered service (subject to charges). → For further information, see Technical information IN 00.15 &#x27;Wake frequency |
