介绍了一种一体化温度变送器现场自动校准装置。通过计算机程序控制,实现了工作温度的自动调节、温场条件的自动判定、数据自动读数及异常值剔除。内置的多路切换模式使六路温度变送器可同时校准。集成化设计和特殊的技术方案使装置具有小型化和便携式特点,并达到以下技术指标:工作温区50~300℃,工作温场的均匀性0.01℃,波动性0.03℃/10 min.,校准结果的不确定度0.07℃(k=2)。
An automatic on-site calibration device for temperature transmitter is introduced. Through computer program control, to achieve the automatic adjustment of operating temperature, temperature field conditions automatically determine the automatic reading of data and outliers. Built-in multi-channel switching mode allows six temperature transmitter can be calibrated simultaneously. Integrated design and special technical solutions make the device miniaturized and portable, and meet the following technical specifications: working temperature range 50 ~ 300 ℃, working temperature uniformity 0.01 ℃, fluctuation 0.03 ℃ / 10 min., Calibration The uncertainty of the result is 0.07 ° C (k = 2).
