    • An embeddable corrosion rate meter (ECRM) for detecting and measuring corrosion in metal and concrete structures comprises an electrochemical cell with an ECRM sensor circuit (20). Circuit (20) includes at least one working electrode (10) evenly spaced from counter/reference electrode (12) with the separation distance between the electrodes determining an electrolyte medium resistance. Circuit (20) also includes a current source generated by power source (28) connected through different resistances RI (26) to Rn (24). A first selector is used in applying current through each or the plurality of resistances to working electrode (10) and a second selector (16) selects a duration of the current pulse. Current is applied between the electrodes through galvanostat (22) and polarization of working electrode (10) is measured by voltmeter/A-D converter (18) connected via link (34). The voltmeter has an input impedance greater than a billion ohms. An external reader-head with power link (32) powers circuit (20) and reads and transfers corrosion measurement data via data link (36) to computer (30).
    • 用于检测和测量金属和混凝土结构腐蚀的嵌入式腐蚀速率计(ECRM)包括具有ECRM传感器电路(20)的电化学电池。 电路(20)包括与计数器/参比电极(12)均匀间隔开的至少一个工作电极(10),电极间的距离决定电解质介质电阻。 电路(20)还包括通过不同电阻RI(26)至Rn(24)连接的电源(28)产生的电流源。 第一选择器用于将电流通过每个或多个电阻施加到工作电极(10),而第二选择器(16)选择电流脉冲的持续时间。 通过恒电流器(22)在电极之间施加电流,并且通过连接(34)连接的电压表/ A-D转换器(18)测量工作电极(10)的极化。 电压表的输入阻抗大于十亿欧姆。 具有电力链路(32)的外部读取器头对电路(20)供电,并且经由数据链路(36)读取并传送腐蚀测量数据到计算机(30)。
