一、产品简介
ZB-AY508Ⅶ型地下管道防腐层绝缘电阻测量仪(套)是由一台“信号源”和二台“选频表”组成。是按变频选频法原理要求研制的测量仪器。变频选频法是针对被测管段长度及被测管段防腐层质量状况,选用不同频率的信号输入管道,并测量信号在管中的传输衰耗(电平差),实现测量连续管道任意长管段防腐层绝缘电阻的。为此,应用测量仪器现场实测的参数有两项,即:测量信号的“频率值”(Hz)及该信号在被测管段的“电平衰耗”(dB)值。2006年定型生产了第七代测量仪器AY-508Ⅶ型 ,实现集成化、小型化、信号频率连续可调、选频测量自动数字显示、精度高,提高了测量的“准确性”和“重现性”。ZB-AY508Ⅶ型管道防腐层绝缘电阻测量仪由一台“信号源”和二台“选频表”组成。

ZB-AY508 Ⅶunderground pipeline anticorrosion layer of insulating resistance measuring instrument ( set) is composed of a " source " and two " frequency table ". According to the variable frequency and frequency principle requirements of the development of special measuring instrument. Variable frequency and frequency method is according to the measured length of the pipe and the tested pipe section coating quality, selection of different frequency signal input pipe, and the signal is measured in the pipe transmission attenuation ( level ), to achieve continuous measurement pipe arbitrarily long pipe anticorrosion layer insulation resistance. Therefore, application of special measuring instrument field parameters has two, namely: the measurement signal " frequency " ( Hz ) and the signal to the tested pipe section " level attenuation" ( dB ) value. In 2006 the production of stereotypes of the seventh generation of special measuring instrument AY-508 Ⅶ, realize the integration, miniaturization, continuous adjustable frequency signal frequency measurement, automatic digital display, high precision, improve the measurement " accuracy " and " reproducibility ". ZB-AY508 Ⅶpipeline anticorrosion layer insulation resistance measuring instrument consists of a " source " and two " frequency table ".
