This protection tube is an important component for temperature measurement points for almost all industrial processes, especially for fine chemicals industries. It is used to protect the measuring insert or sensor elements from aggressive process media, high pressures and flow rates from the temperature sensor itself and thereby enables the thermometer to be exchanged during operation.

TW13 protection tubes are important components for temperature measurement points for almost all industrial processes, especially for fine chemicals industries.

• Extension, immersion length and total length can be chosen according to process requirements

• A wide choice of dimensions, materials and process connections is available

• Special versions can be manufactured according to customer requirements
