Meaning position at least offers an outlet, and the outside extension of outlet is formed with one section of fairlead, and fairlead is detected with high temperature
After probe cooperation, carry out hermetically sealed process.
In thorax humidity device for fast detecting in above-mentioned steaming and baking box, alternatively, described oxygen sensor is limit-current type oxygen
Change zirconium oxygen sensing, it is possible to achieve the measurement of oxygen concentration under 250 DEG C of hot environments, the impact of water vapour not only can be reduced, and
And used due to long-time, the tiny dust in tested gas can reduce the diffusion hole area s of oxygen sensor, bring coefficient k
Change, lead under test data drift, this oxygen sensor has zero offset capability.
In thorax humidity device for fast detecting in above-mentioned steaming and baking box, alternatively, in the opposite wall of thorax in described steaming and baking box or
One outlet is respectively offered on adjacent wall, the outside extension of outlet is formed with one section of fairlead, each fairlead built-in
Individual oxygen sensor, forms the detection of multiple spot oxygen content, improves the accuracy of thorax Humidity Detection data in steaming and baking box.
It is a further object of the present invention to provide thorax humidity method for quick in a kind of steaming and baking box, the method includes: obtains
Take the oxygen content signal of thorax in the steaming and baking box being uploaded by oxygen sensor, controller by calculating to signal ambiguity, using preset
Data base preserves to Fuzzy Calculation data, in a period of time, detects multiple humidity and is counted, draws accurately
Humidity Value Data to user feedback, reaches the precise control to thorax humidity in steaming and baking box.
Compared with prior art.The invention has the advantage that
1), the structure of the detecting device of the present invention is simple, and low manufacture cost has extensive generalization;
2), the principle that the present invention is directly proportional to oxygen content using humidity, by detecting the oxygen content of gas in thorax in steaming and baking box, so
Draw the humidity in thorax in steaming and baking box afterwards again by Fuzzy Calculation, can be by examining to the humidity of thorax in steaming and baking box in real time
Survey, Humidity Detection numerical value accurately, during this numerical value is sufficiently applied to the scorching of food, can be very good to ensure food mouth
Sense is optimal, is of high nutritive value.
