[Model] LSV-A-121 Cooled Protective Housing [Description] 
To handle hot and hostile environments in rolling mills and continuous casters, Polytec has developed a Cooled Protective Housing consisting of an aluminum housing with integrated stainless steel cooling coils. The coolant can be water, rolling coolant, paraffin oil or kerosene. An optional heat shield protects the system from radiated heat, from the measurement object itself or other heat sources.
