【摘要】 讨论了恒流源作为电源的惠斯登电桥的灵敏度。研究表明灵敏度与恒流源输出电流成正比,并且桥臂电阻比例越小,灵敏度越高;当保持桥臂电阻比例不变时,桥臂电阻数值越大时灵敏度越高。研究表明两种电源所构成的电桥灵敏度影响因素完全不同。更多还原

【Abstract】 The sensitivity of Wheatstone bridge circuit using constant-current source has been discussed. The experimental and theoretical results show that the sensitivity is proportional to the output current of the source,and exhibits greater value with decreasing the resistance ratio of the bridge-arm resistors and increasing the value of the bridge-arm resistors.更多还原
