摘要
该文介绍了一种由电子天平、目标靶、吸声罩及支撑装置组成的超声功率计的设计与研制。这种超声功率计的电子天平安装在支撑装置上,并使用连杆与目标靶固定连接;通过调节支撑装置可使目标靶悬于超声探头正上方,从而对固定探头的超声功率进行测量。经过对样机的初步测试,其测量稳定且精度较高。
This article describes the design and development of an ultrasonic power meter which is consist of an electronic balance, a practice target, an acoustic enclosures and a blocking. The electronic balance mounted on the blocking is linked with the practice target by connecting rod. By adjusting the blocking makes the practice target suspended above ultrasound probe, and then the ultrasonic power can be measured. After initial tests, the ultrasonic power meter performanced with good stability and high precision.
