This sensor assembly is a very common one used in many process applications. It consists of a Pt100 sensing element housed in a stainless steel protective sheath with a process thread fixed below the termination head which can be Aluminium, Plastic or Stainless Steel. 6mm would be a standard diameter for this probe and some stock lengths are 100mm up to 300mm in increments of 50mm. Other diameters & lengths are also available.
