摘要
传统直流电位差计的更新换代产品直流数字式电位差计,能够直接输出或测量直流毫伏信号和电流信号,常用于校准多种型号的变送器和热电偶等,然而,直流数字式电位差计量值溯源方法尚无可依据的国家技术规范.文章从计量特性、校准条件、校准方法等方面分析,探讨解决直流数字式电位差计的量值溯源问题.
Abstract
DC digital potentiometers is the updated product of traditional DC Potentiometersis.It can di-rectly output or measure DC millivolt signals and current signals.It is often used to calibrate various mod-els of transmitters and thermocouples.However,there is no national technical specification for the tracea-bility method of DC digital Potentiometersis.This article analyzes the measurement characteristics,cali-bration conditions,calibration methods,and other aspects to explore the solution to the traceability prob-lem of DC digital potentiometers.
