This sensor assembly is generally used within the dairy, brewery & pharmaceutical industry where a sanitary process connection is required. It consists of a Pt100 sensing element housed in a stainless steel protective sheath with a floating Din 11851 style fitting & a lag/standoff. These assemblies are generally of a high surface finish as required for such processes. The termination head which can be Aluminium, Plastic or Stainless Steel.
