| 20090041086 | Furnace temperature monitoring device and method - A method for measuring the temperature at various locations in a furnace adapted to heat-treat a metal part commences by placing one or more devices at various location within the furnace. Each device is an inorganic/metallic skeletal structure residual from firing a mixture of binder and one or more of inorganic or metallic particles at a temperature that chars the binder to form the inorganic/metallic skeletal structure of a determined shape. A physical parameter of the skeletal structure determined shape is monitored after firing of the furnace. Then, the monitored physical parameter is compared to a plot of temperature versus the physical parameter to determine the temperature of the furnace at the various locations. | 02-12-2009 |
