SCYC 56901温度传感器是·早开发,应用·广的一类传感器。温度传感器的市场份额大大超过了其他的传感器。从17世纪初人们开始利用温度进行测量。在半导体技术的支持下,本世纪相继 开发了半导体热电偶传感器、PN结温度传感器和集成温度传感器。
SCYC 56901两种不同材质的导体,如在某点互相连接在一起,对这个连接点加热,在它们不加热的部位就会出现电位差。这个电位差的数值与不加热部位测量点的温度有关,和这两种导体的材质有关。
SCYC 56901这种现象可以在很宽的温度范围内出现,如果·确测量这个电位差,再测出不 加热部位的环境温度,就可以准确知道加热点的温度。
SCYC 56901由于它必·有两种不同材质的导体,所以称之为“热电偶”。不同材质做出的热电偶使用于不同的温度范围,它们的灵敏度 也各不相同。
SCYC 56901热电偶传感器有自己的优点和缺陷,它灵敏度比较低,容易受到环境干扰信号的影响,也容易受到前置放大器温度漂移的影响,因此不适合测量微小的温度变化。由于热电偶温度传感器的灵敏度与材料的粗细无关.
SCYC 56901 Temperature sensors are the earliest developed and most widely used type of sensors. The market share of temperature sensors greatly exceeds that of other sensors. From the beginning of the 17th century, people began to use temperature to measure. With the support of semiconductor technology, semiconductor thermocouple sensors, PN junction temperature sensors and integrated temperature sensors have been developed successively in this century.
SCYC 56901 If two conductors of different materials are connected to each other at a certain point, and the connection point is heated, a potential difference will appear in the unheated parts of them. The value of this potential difference is related to the temperature of the measuring point in the unheated part and to the materials of the two conductors.
SCYC 56901 This phenomenon can occur in a wide temperature range. If the potential difference is accurately measured, and then the ambient temperature of the unheated part is measured, the temperature of the heating point can be accurately known.
SCYC 56901 Because it must have two conductors of different materials, it is called a "thermocouple." Thermocouples made of different materials are used in different temperature ranges, and their sensitivities also vary.
SCYC 56901 The thermocouple sensor has its own advantages and disadvantages. Its sensitivity is relatively low, it is easily affected by environmental interference signals, and it is also easily affected by the temperature drift of the preamplifier, so it is not suitable for measuring small temperature changes. Because the sensitivity of the thermocouple temperature sensor has nothing to do with the thickness of the material.
