本文叙述了在温度控制中,除了考虑基型传感器一些显而易见的特性外,还必须考虑到的谐因素。要想控制温度,就必须精确地检测温度,如热电偶和热电阻温度计有许多可能会产生误差的因素。为了精确地控制温度,不仅要考虑基型传感器的特性,而且还要考虑:污染的影响、导线的长度、浸入液体、热传导及控制器 This article describes the harmonic factors that must be considered in temperature control, in addition to taking into account some of the obvious characteristics of a base sensor. To control the temperature, you must accurately detect the temperature, such as thermocouples and RTD thermometer there are many factors that may produce errors. In order to precisely control the temperature, not only the characteristics of the base sensor but also the effects of contamination, the length of the wire, the immersion in the liquid, the heat conduction and the controller
