在非电量电测技术中,传感器是将非电量变换成电量的一种能量转换装置,因此它的精确度直接影响整个测量系统的测试精度,如果传感器的精确度很低,后面所用的显示仪表精确度再高,其测试结果也不可能获得高的精确度。同样,它的稳定性、可靠性也对测试精度有着重要的影响,因此传感器在非电量电测技术中是一个关键的部份。在国外,对于传感器的研究和生产是比较重视的,发展也是很快的,以英国为例,英国 In non-electric measurement technology, the sensor is an energy conversion device that converts non-electricity into electricity. Therefore, its accuracy directly affects the measurement accuracy of the whole measurement system. If the accuracy of the sensor is very low, the display instrument High accuracy, the test results can not get high accuracy. Similarly, its stability and reliability also have an important impact on the accuracy of the test, so the sensor in non-electric measurement technology is a key part. In foreign countries, the research and production of sensors are more important, the development is also very fast, the United Kingdom, for example, the United Kingdom
