【摘要】：溫度是科學(xué)研究中最普遍的物理量,也是生產(chǎn)精密儀器的重要參數(shù),然而國(guó)內(nèi)對(duì)于高溫環(huán)境除熱電偶測(cè)溫傳感器外尚無(wú)可靠的原位測(cè)試方法。依據(jù)超聲導(dǎo)波測(cè)溫的原理,設(shè)計(jì)出一套基于磁致伸縮效應(yīng)的超聲導(dǎo)波測(cè)溫裝置,測(cè)試了該裝置在常溫以及常溫(12℃)~600℃的運(yùn)行情況。實(shí)驗(yàn)表明,該裝置可以在高溫環(huán)境下穩(wěn)定運(yùn)行,并且得到常溫(12℃)~600℃范圍內(nèi)的起始聲波和端面回波之間時(shí)間間隔△t與介質(zhì)溫度之間的對(duì)應(yīng)關(guān)系,為2 000℃以上的高溫測(cè)量奠定了基礎(chǔ)。
[Abstract]:Temperature is the most common physical quantity in scientific research, and it is also an important parameter in the production of precision instruments. However, there is no reliable in-situ measurement method for high temperature environment except thermocouple temperature sensor. According to the principle of ultrasonic guided wave temperature measurement, a set of ultrasonic guided wave temperature measuring device based on magnetostriction effect was designed, and the operation of the device at room temperature and normal temperature (12 鈩，
