Abstract
Measurement and display of the temperature of a cooking surface of a cooking utensil is provided by a temperature sensor, such as a thermocouple, in thermal contact either directly with the cooking surface or through a clamp on the side of the cooking utensil in close proximity to the cooking surface, and a temperature measuring and display electrically connected to the sensor at a location on the handle of the cooking utensil or on the upper end of the clamp for convenient viewing of the temperature of the cooking surface at a location away from the temperature sensor.
Claims3
Apparatus for measurement and display of a cooking surface temperature of a cooking surface in a utensil comprising
- a temperature sensing means in direct thermal contact with a cooking surface for producing a voltage proportional to said cooking surface temperature,
- means connected to said temperature sensing means for quantitative measurement of said voltage produced proportional to said cooking surface temperature, and
- conversion means electrically connected to said voltage measurement means for converting said quantitative measurement of said voltage into displayed calibrated units of temperature, said conversion means being mounted for viewing on said utensil for display of said quantitative voltage measurement calibrated in units of temperature wherein said temperature sensing means is embedded to said cooking utensil at a point in a bottom wall of said cooking surface, and a pair of insulated electrical leads connecting said temperature sensing means embedded in said wall for coupling said voltage produced by said temperature sensing means to said quantitative voltage measurement means, said quantitative voltage measurement means being disposed at a location on said cooking utensil remote from said cooking surface.
