(2)小型长图记录仪XWD_1系列测温仪表是一种带指示温度的记录仪表,根据所记录的测点数量分为单笔、双笔和多点记录三种类型。仪表配有电动走纸机构,测点温度的变化能随时间变化在记录纸上绘成曲线。单笔测量记录一点参数,双笔同时测量记录二点参数,多点分三点和六点,是采用轮换在记录纸上打点记录,并以不同颜色点区别各测点温度值。和XCZ、XCT动圈表系列一样,配用铂热电阻组成温度测量和控制系统,仪表和铂热电阻也采用三线制连接,每根导线的电阻
(2) Small Long Diagram Recorder XWD_1 series temperature measuring instrument is a recording instrument with indicating temperature. It is divided into single, double and multi-point recording types according to the number of recorded measurement points. The instrument is equipped with a motorized paper-feeding mechanism, and the change of the measuring point temperature can be plotted on the recording paper with time. Single measurement and recording of one parameter, two-stroke simultaneous measurement and recording of two-point parameters, multi-points are divided into three points and six points. It is to use rotating records on the recording paper, and distinguish the temperature value of each measuring point by different color points. As with the XCZ and XCT series of dynamic coils, platinum resistance thermometers are used for temperature measurement and control systems, and the instrument and platinum thermal resistance are also connected in a three-wire system with the resistance of each wire.
