美国 Sandia 国家试验室研制成一种超声波温度计能准确地测量高温。这种超声波高温计可工作在常规温度计(诸如热电偶和光学高温计)不能应用的场合。它是用将超声波传播速度的变化转换为沿感温丝各点上的温度的方法来测温的。测量温度高达2850℃。(原文为285℃,疑有误)。利用声波测温已有好几年的历史,但是,Sandia研制的温度计头一次把这种技术用于高温科研领域。Sandia 高温计的成就归因于材料的选择及其热时效
US Sandia National Laboratory developed into an ultrasonic thermometer can accurately measure the high temperature. This ultrasonic pyrometer can work in conventional thermometers (such as thermocouples and optical pyrometers) can not be applied to the occasion. It measures temperature by converting the change in ultrasonic propagation velocity to the temperature at each point along the temperature sensing wire. Measuring temperature up to 2850 ℃. (The original is 285 ℃, suspected wrong). Sonic temperature has been used for several years, but the thermometer first developed by Sandia uses this technique for high-temperature research. The achievements of the Sandia Pyrometer are due to the choice of materials and their thermal aging
