天天时时彩 二、PT100温度传感器工作原理及其主要技术参数

Pt100传感器是利用铂电阻的阻值随温度变化而变化、并呈一定函数关系的特性来进行测温,其温度/阻值对应关系为[1]:
(1)-200℃<t<0℃时,RPt100=100[1+At+Bt2+Ct3(t-100)] (1)
天天时时彩 (2)0℃≤t≤850℃时,RPt100=100(1+At+Bt2) (2)

虽然在过去的PC和笔记本计算机中,温度传感器并不起眼,也没有工程师会去注意它的重要性,更不用说使用者能感觉到它的存在。但是,对整个系统这些重要芯片来说,它是很重要的保护者,尤其是当系统愈来愈高速且愈来愈热之后,它的重要性也会更加明显,并且能左右系统的稳定性。希望本文能够带给读者一个清晰的印象,究竟温度传感器在PC系统中是扮演哪些角色?也希望工程师在验证系统稳定性时,不妨考虑一下温度传感器的一些重要参数和功用。
