【摘要】 虽然应变式电阻压力传感器得到广泛应用,但对传感器本身的灵敏度的测试却鲜有研究.为此,提出了测量应变式电阻压力传感元件灵敏度的方法,并设计了测量电路,对其灵敏度进行了理论分析、推导和实验测量与验证.该方法有助于学生深入了解该传感器的性能及其应用技术.更多还原

【Abstract】 Although strain resistance pressure sensors were widely used,the sensitivity of the sensors themselves had rarely been studied.Now,A method for measuring the sensitivity of strain resistance pressure sensors was proposed,and a measurement circuit was designed.The theoretical analysis and derivation,the experimental measurement and verification were carried out.This method could help students deeply understand the performance of the sensor and its suitability.更多还原
