直读式混凝土厚度超声检测仪研制及应用

Development and application of ultrasonic detector for method directly measuring the cement concrete thickness

本文主要介绍直读式混凝土厚度（直接显示厚度）超声检测仪电路原理、换能器特性以及模拟实验与现场实际混凝土测厚应用结果。在３０ｃｍ厚度范围内检测误差小于５％。

This paper described the circuit principle of the ultrasonic cement concrete thickness detector (which displaying thickness directly).The property of its transducer and the applied results of thickness detected in the simulated experiments and in situ, are mainly introduced. Within 30cm of the concret thickness the detecting error is about 5%.
