Endress + Hauser TT511 Industrial thermowell

For Oil & Gas applications. Vanstone type, design with collar flange

It is a specially designed thermowell for thermometer installation. The thermowell shaft and the process 

connection flange are not interconnected. For installation, the collar of the thermowell is fitted between two flanges; 

on the one hand it is fitted onto the thermowell and on the other 

hand it is bolted to the connection nozzle on the process side. Many different flange versions are available to secure 

the unit to the permanently installed nozzle flange. It is machined from solid bar stock.

Benefits

Solid thermowell, made of drilled bar stock material.

Fulfillment of various, industry specific requirements with a standard product. Flexible selection of immersion length 

and thermowell geometry according to the process specifications.

In accordance with Shell specification: S.38.113 rev.D and S.38.114 rev.D

Exact thermowell stress calculation ensuring safe plant operation.

Vanstone design with outstanding cost effectiveness:

Reuse of the flange if the thermowell has to be replaced, flexible selection of the flange material 

as well as reduced spare parts and storing concept.

Field of application
The thermowell will be used in applications with high process requirements. The predominant industries are Oil & Gas and Petrochemical. 

The process connection flange is not welded on the thermowell stem but designed as collar flange. This special Vanstone 

thermowell design enables a wide variety of applications and is suitable for resistance and thermocouple thermometers.
