随着电子计算机在工业上的广泛应用,一些非电量如何能直接转换为电数字量,以便能直接送入电子计算机,就成为现代传感器研究的一项新课题.大家知道,过去的传感器极大部分是属于模拟式传感器,也就是说,这种传感器将诸如温度、压力、位移等非电量转换为电模拟量(如电压).这样要用数字显示或送入电 With the widespread use of electronic computers in industry, how non-electric quantities can be converted directly into digital quantities so that they can be sent directly to electronic computers have become a new topic in the research of modern sensors. As we all know, sensors of the past are extremely large Part of the analog sensor, that is, the sensor will be such as temperature, pressure, displacement and other non-electricity into electrical analog (such as voltage) .To use digital display or send electricity
