摘要
采用高阻定值技术与显示控制技术相结合的创新方法,研制了一种能够数字显示的轻质燃油电导率仪计量标准装置。该装置使用的高阻值为1×10^9~2×10^10Ω,高阻准确度达到1%,温度系数不大于2.00×10^–4。经过校准后显示的标准高阻信号实际输出值的精度达到0.05%。该装置操作简单便捷,准确度高,能满足轻质燃油电导率仪校准的要求。
A new measuring standard device for light fuel conductivity meter with digital display was developed by combining high resistance setting technology with display control technology. The high resistance value used in this device was 1×10^9–2×10^10 Ω, the high resistance accuracy was 1%, and the temperature coefficient was not more than 2.00×10^–4. After calibration, the actual output accuracy of standard high resistance signal could reach 0.05%. The device is simple and convenient to operate,and it has high accuracy. It can meet the requirements of the personnel who calibrate the light fuel conductivity meter.
