temperature excursion
1.A method of temperature compensation for pressure sensor is introduced, and it resolves the problem which is about the temperature excursion of pressure sensor.
2.Contraposing the measurement principle of the traditional hotwire air mass flowmeter, the reason of the excursion of the result for flow measurement was analyzed and inferred when environment temperature changed; The method for temperature compensation and the realization circuit was given; and compared the theory output of the new type hotwire air mass flowmeter with its real output after temperature compensation.
