随着材料科学和工业发展,表面涂层镀层工艺越来越广泛地得到应用。为此研究了精密,快速、无损检测技术和研制了数字化、智能化JCH-3a涂镀层智能测厚仪。该仪器采用了高精度一次探头仪表,大规模集成电路和微机技术,它具有数字显示测量点地址和厚度,数字预置上下限分类报警阈值和取样率,自动记忆存储数据,可查询修正数据和打印输出等功能。全机轻便、尺寸小、测量范围广,可用于钢铁部件上Zn,Cr,Sn,Ag,油漆、搪瓷、塑料等涂镀层及非磁性材料镀镍层精密厚度测量,测量范围为0～300μm,相对误差3～4%,0～10μm,测量精度可达±0.2μm.该仪器可用于反应堆板型燃料元件总厚和水道间隙精密测量等。
With the material science and industrial development, surface coating technology is more and more widely used. For this reason, the research of precision, rapid, non-destructive testing technology and development of digital, intelligent JCH-3a coating thickness gage. The instrument uses a high-precision primary probe instruments, large-scale integrated circuits and computer technology, which has a digital display measuring point address and thickness, digital preset upper and lower limits alarm threshold and sampling rate, automatic memory storage data can be found in the correction data and Print output and other functions. The whole machine is light, small size, wide measuring range, can be used for the precise thickness measurement of the coating layer of Zn, Cr, Sn, Ag, paint, enamel, plastic and the non-magnetic nickel plating layer on the steel parts. The measuring range is 0-300μm, The relative error of 3 ~ 4%, 0 ~ 10μm, measurement accuracy of ± 0.2μm. The instrument can be used for reactor plate fuel element total thickness and waterway clearance precision measurement.
