一、前言 XMT系列数显温度调节仪具有精度高、稳定性好、使用方便、读数直观清晰、无视差、寿命长以及维修校正简单等特点,所以,它广泛用于冶金、机械、石油、化工等工矿企业及科研单位。该系列仪表的调节型式同XCT系列动圈式指示调节仪一样,也具有位式调节、时间比例调节和连续的PID调节等方式。现场使用位式调节器或时间比例调节器时,由于各种加热对象特性不同或在同一加热对象的不同控温段,要求被测温度稳定在设定温度时,对象所需的平均加热功率不一
I. INTRODUCTION XMT series digital thermostat has many advantages such as high precision, good stability, easy to use, intuitive and clear reading, no parallax, long service life and simple maintenance and correction. Therefore, it is widely used in metallurgy, machinery, petroleum, chemical industry Other industrial and mining enterprises and research institutes. The series of instruments with the adjustment of the XCT series moving coil indicator, also has a bit adjustment, time proportional adjustment and continuous PID adjustment and other means. When the position regulator or time proportion regulator is used on site, due to different characteristics of heating objects or different temperature control sections of the same heating object, it is required that when the measured temperature is stable at the set temperature, the required average heating power of the object is not one
