摘　　要：在研究漏磁场原理的基础上,设计了一种电动式储罐底板漏磁检测仪,该检测仪由机械扫查探测部分和信号处理部分组成.实验室和现场试验表明,该小型储罐底板腐蚀漏磁检测仪检测效率高、可靠性好,而且便于携带和操作,有效地解决了储罐底板腐蚀的检测问题.Based on the magnetic flux leakage （MFL） technique, a magnetic flux leakage testing instrument for corrosion in the tank floor plate driven by electric motor is developed. This instrument is made up of scanning and testing part and signal processing part, and especially, the scanner is driven by the electric motor. The laboratory and field test results indicate that this type of MFL instrument for tank floor plate has high sensitivity, reliability and inspecting efficiency. It is an efficient approach to the testing of the corrosion in the tank floor plate.
