What is a Protection Tube?

Protection Tubes are used to protect sensors, usually thermocouples, against contaminating atmospheres and/or mechanical damage. Closed at one end, they usually incorporate some means by which the tube, sensor and connection head are assembled and mounted into the process. The Protection Tube material is selected on the basis of the environment to which the sensor assembly will be subjected.
