4.3 Description
The model TW61 protection tube is used to adapt thermometers and measuring inserts
to the process and protects the sensor against harsh process conditions. Furthermore, it
enables the removal of the temperature probe without having to open the process.
To integrate it into the process, the thermowell / protection tube is directly orbitally
welded into a pipeline. The connection ends are smooth and prepared for orbital
welding.
In combination with a resistance thermometer, the swivel connection of the connection
head or the indication can be loosened and turned to the desired orientation. The
measuring insert can be withdrawn together with the connection head. In this way, it
is possible to calibrate the entire measuring chain (sensor, transmitter if applicable,
connection cable) on-site, without having to disconnect the electrical connection. In
addition this avoids having to open the process, and thus the risk of contamination is
minimised. The thermowell / protection tube is not piggable.
