Measurement of the temp. in baking ovens - has temp. probe shielded from direct radiation from the heating elements so as to measure more accurately the oven air temperature

摘要

A temperature probe (9) is located in a baking oven out of the range of the radient heat from the heating elements (2, 3) and thus measures the true air temperature in the oven interior (1). This probe is connected to a relay controlling the power supply to the heating elements. The probe may be shielded from the radient heat or may be located in the air outlet duct (8) from the oven. USE/ADVANTAGE - Used for measuring the temperature in baking ovens, and avoids the errors in measurement currently experienced when the temperature probe is exposed to direct radiation from the heating elements. These errors lead to uneven heating when the product is placed in the oven, since the drop in temperature caused by the initial evaporation of moisture from the product is not correctly perceived by the temperature probe. When the temperature probe is shielded from the heating elements, a more closely controlled temperature is achieved and the quality of the product is therefore improved.
