【摘要】 由于压力传感器输出出现零点电漂移,不同激励电压零点便不同。本文介绍应怎样选择其激励电压值,同时分析了集成稳压电路的电压输入输出特性以及利用它对传感器供电消除热零点漂移同时又使零点偏移为零,并用实验加以验证。更多还原

【Abstract】 As a result of electric drift of the offset in pressure sensor , the offset will vary with different activating voltage. We introduce how to choose activating voltage for pressure sensor, analyze output voltage characteristic of an integrated regulate circuit vs input voltage and the principles to eliminate thermal drift of the offset and in the same time make it zero , furthermore did experiments to verify the principles.更多还原
