Calibration device for a dental furnace |
| abstract |
A calibration device for a dental furnace includes a meltable element located on a hollow tube. The melting of the meltable element breaks the seal and reduces the vacuum pressure in the furnace thereby triggering the controller to calibrate the temperature of the furnace to the melting temperature of the meltable element. Alternatively, a calibration device comprises a solid tube having a groove thereon is positioned in the furnace and a metal strip is positioned on the solid tube. Upon melting of the metal strip, the solid tube is displaced and the seal is broken allowing air from the external environment to access the furnace atmosphere. The change in vacuum pressure is detected and the temperature in the furnace and the melting point of the metal strip is used as the reference temperature to calibrate the furnace. |
