pt100的应用

石油倾点温度测试PT100温度传感器的标定

摘要:作者设计了直径为3mm、长为27cm 的Pt100型传感器,根据0.10℃刻度的温度测试仪作为标定标准,利用软件来矫正其非线形失真,该产品实现对石油倾点温度信号的采集和标定。
关键词: Pt100传感器;电桥测温;石油倾点


一、引言

石油倾点温度是指管道内凝固态的原油开始融解流动的*低温度。国际上测试规程要求每隔2℃就要对其流动情况进行判断并测温,但由于石油运输管线很长,原油每升温1℃需要大量能源,因此对倾点温度测量的精度对油田节能有重大意义。我们选用PT100温度传感器众鑫彩票来完成对石油倾点温度的测量。


众鑫彩票 二、Pt100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)
(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。
