概述电阻式金属测厚仪与应用放射线的仪器相比,价格是非常低廉的,而且无需特殊的技术和特殊的技术熟练工人,因此,在应用超声波仪器的同时在现场多使用此仪器。此仪器称之为斯麦克测定仪,可对锅炉蒸汽管道、水压钢管、船体钢板、化工厂的压力容器等及各种金属构件的壁厚和裂缝直接从一侧测出,作 Overview Resistive metal thickness gauges are very inexpensive compared to radiographic instruments and require no special technology or special skilled workers. Therefore, more use of this instrument is available on site while using ultrasonic instruments. This instrument is called Simaike tester, which can directly measure the wall thickness and cracks of boiler steam pipe, water pressure pipe, hull steel plate, chemical plant pressure vessel, etc. and various metal components for
