电子仪器在50年代以前是以测电量为主,到了70年代便成为以测非电量为主。目前,电子仪器的市场大约有90%为非电量电测仪器。而且电子仪器基本上已吞并了大部分的电工仪器、热工仪器、机械仪表及光学仪表,使仪器仪表原先的分类方法变得模糊了。现在除了一些面板式电表、光学测量仪表及某些简单价廉的机械仪表外,大部分都电子化了。特别是计算机技术同电子仪表结合后,新一代智能仪表的问世给电子仪表行业带来了革命性的变化。电子仪器发展到非电量测量阶段,主要是由于传感技术飞速发展的结果。现代的传感器几乎能将绝大部分的非电量转变为电量。传感器(sensor)早先称为换能器(transducer),直到70年代,原电子工业部才统一命名,称之为传感 Before the 1950s electronic devices were based on measuring electricity, and by the 1970s they became the main measure of non-electricity. At present, about 90% of the market for electronic devices is non-electric measuring instruments. And electronic equipment has basically annexed most of the electrical equipment, thermal instrumentation, mechanical instrumentation and optical instrumentation, instrumentation, the original classification method has become blurred. With the exception of some panel meters, optical gauges and some simple and inexpensive mechanical gauges, most are now electronic. In particular, the combination of computer technology and electronic instruments, the advent of a new generation of smart meters to the electronic instrumentation industry has brought a revolutionary change. The development of electronic devices to non-power measurement stage, mainly due to the rapid development of sensing technology results. Modern sensors convert almost all non-electricity to electricity. Sensor (sensor) Earlier known as transducer (transducer), until the 70s, the former Ministry of Electronics Industry unified name, called sensing
