一、前言玻璃液体温度计(包括带电接点的玻璃水银温度计)因其结构简单,静态精度高,使用方便和价格低等优点,在温度的测量和控制中应用非常普遍。但是,在实际中经常碰到的是动态的测温或控温问题,这是因为被测控的流体温度事实上总是随时间变化的。由于通常的玻璃液体温度计存在较大的热惯性,因此在用于动态温度测控时,会产生较大的动态误差。所以本文在分析玻璃液体温度计动响特性的基础上,讨论了具有高响应的温度计感
I. Introduction Glass thermometers (including charged mercury glass thermometers) are widely used in temperature measurement and control due to their simple structure, high static accuracy, ease of use and low price. However, in practice, the problem of dynamic temperature measurement or temperature control is often encountered because the temperature of the fluid under test always in fact changes over time. Due to the large thermal inertia of glass liquid thermometers, large dynamic errors occur when used for dynamic temperature measurement and control. Therefore, based on the analysis of the dynamic characteristics of glass liquid thermometer, this paper discusses the thermometer with high response flu
