Title:
GAS RATE SENSOR
Document Type and Number:
Japanese Patent JP3244208
Kind Code:
B2
Abstract:
PURPOSE: To provide a gas rate sensor of high sensitivity which is not sensitive for the acceleration in compliance with the inclination in the roll direction nor the acceleration in the yaw (horizontal) direction but is sensitive solely for the angular velocity.
CONSTITUTION: A gas rate sensor includes a sensing means 7, which senses change in the resistance value associated with heat radiation of a pair of heat- emissive thermal sensitive resistance sensors resulting from the deflection of a gas flow and senses an angular velocity signal ωo complying with the angular velocity in the yaw direction, and a pump control means 8 which adjusts the pump voltage Vp of a piezo pump 5 so that heat radiations of the two resistance sensors become equal in sensing the acceleration and an acceleration signal Go given by the sensing means 7 nullifies through a deflection of the gas flow generated by setting the gas flow to a certain level.
