Pyrometry sheaths for use in furnaces

Morgan Molten Metal Systems recently announced the release of its HotRod pyrometry sheaths and other pyrometer assembly products, which are made of an erosion-resistant clay-graphite mix with special plasticity properties and protect thermocouples in furnace heating control systems.

The pryometer assemblies are designed to have a metal wire inserted into them and then placed into a metal bath to measure the temperature. HotRod sheaths, designed for use in furnaces and other high temperature environments, are supplied with a 12.7mm threaded steel tube for attachment to the furnace pyrometry system.


The pyrometer assemblies are durable, with a glaze on the ceramic exterior that protects the product from oxidation, thereby reducing downtime. These assemblies offer effective thermocouple protection with high thermal conductivity for fast, accurate temperature readings and reduced fuel consumption. Single pyrotubes are heat resistant to 1600C, while the HotRod sheaths with inner steel tubes are resistant to 1000C and are typically used for aluminium applications. HotRod products require no special tools for installation.
