摘要：

高温气体瞬时温度的测量一直是温度测量中的难点,主要原因是温度高,压强大,温度变化速度快。传统的温度测量方法,无法实现温度的快速准确测量。在理想气体中,超声波的传播速度与气体绝对温度的平方根成正比,利用超声波频率差的测量测得气体介质的温度。基于此,本文提出了一种超声温度测量方法并实现了测量系统,同时解决了系统探头的安装、高速计数和数据的二次脉冲锁存问题。

Abstract: It is always a very difficult problem to measure instantaneous temperature of high temperature gas.That temperature being high,pressure being big of gas and velocity changing being quick of measured gas is the main causes.The conventional methods of measuring temperature cannot realize quick and exact measurement.So the paper introduced a method of measuring burning gas temperature based on ultrasonic technology and solved problems of installation of probe,high frequency counter and the second pulse lock up data.The velocity of ultrasonic transmitting is direct proportion to the square root value of gas kelvin in the ideal gas.The gas temperature can be measured by the frequency change.

Keywords: Ultrasonic; Temperature measure; High temperature gas; High frequency counter
