一、编制背景接触式数字温度计以铂热电阻、热敏电阻或热电偶等作为传感器,采用A/D转换技术,显示测量温度。部分较高准确度的数字温度计甚至还带有CPU,具有单位转换、数据储存、查询计算等更多的使用功能。其温度测量范围一般在-50℃~1000℃之间。接触式数字温度计已经得到广泛使用,但目前尚无国家计量检定规程或校准规范。各计量部门都在根据自身的技术能力和顾客的需求编制接触式数字温度计校准方法。
First, the preparation of the background Contact digital thermometer with platinum thermal resistance, thermistor or thermocouple, etc. as a sensor, using A / D conversion technology, showing the measured temperature. Part of the higher accuracy of the digital thermometer even with a CPU, with a unit conversion, data storage, query calculation and more use of features. The temperature measurement range is generally between -50 ℃ ~ 1000 ℃. Contact digital thermometers have been widely used, but there are currently no national metrological verification procedures or calibration specifications. The measurement departments are based on their own technical capabilities and customer needs prepared contact digital thermometer calibration method.
