运动织物表面温度的测量

Measurement of the Surface Temperature of a Moving Fabric

本文讨论了低于环境温度的运动织物的温度测量。它的原理是利用传感器与被测体靠近时,通过热交换形成梯度为零的温度场,因而二者温度相等。这种零温度梯度的温度场是通过对传感器的致冷跟踪被测体的温度形成的。本文介绍了测温原理,检测与致冷装置,反馈控制电路以及测量结果。

Measurement of the temperature of a moving fabric at a temperature below ambient is described in this paper.The principle is that a uniform temperature field with no gradient will form by heat exchange when a transducer is close to the measured object,Therefore,their temperatures are egual.The cause forming the uniform temperature field with no gradient is to extract heat from the transducer and to follow the temperature of measured object.The paper introduces the principle of temperature measurement,detecting and chilling devices,feedback control circuit and result of measurement.
