METHOD OF OPERATING A RESISTIVE HEAT-LOSS PRESSURE SENSOR
摘要
<p>In a resistively heated heat-loss pressure gauge, electrical current is switched between a sensing element and a compensating element at different duty cycles. As a result, the sensing element is heated relative to the compensating element. A fixed resistance is placed in series with at least the compensating element. The current source applies current to heat the sensing element to a temperature at which the resistance of the sensing element matches the combined resistance of the compensating element and the fixed resistive element.</p>
