Pyrosil D® has been developed as a very strong thermocouple sheath with high temperature corrosion resistance and extremely low levels of contaminants that could cause degradation over time. As such, it is the mineral insulated cable sheath of choice in high temperature industries with extremely challenging atmospheres and/or environments. For example, it is now considered standard practice for major refinery companies to use Pyrosil D® sheathed thermocouples in furnaces. .
Some specific examples of other industries where Pyrosil D® is used include temperature monitoring in incinerators and furnaces such as in an aluminium anode bake furnace. In gas or steam turbines Pyrosil D® sheathed MI cable can be used to monitor the turbine blade path and exhaust gas. Lastly, Pyrosil D® is very useful in industries such as glass and component manufacture where contamination levels need to be kept low.
Overall, Pyrosil D® cable is the preferred choice in a wide range of high temperature industries including:
Reducing sulphurous atmospheres are not recommended for Pyrosil D® products unless the temperature is below 500°C.
