The thermowell is an important component of the temperature measuring point and is suitable for almost all industrial processes, especially in the oil & gas industry. It protects the measuring insert or measuring component against corrosive process media, high pressure and the flow of the temperature sensor itself, thus ensuring that the thermometer can be replaced during operation.
Advantages
Thermowell manufactured from welded tube
Flange process connection
Extension neck, insertion depth and total length can be selected according to process requirements
Special versions can be produced according to customer requirements
Application
The thermowell is designed for use in the oil & gas industry and can also be used in conventional applications. The modular design ensures it can be used in all industrial processes with severe thermal and mechanical stress.
