FOXBORO电导率电极871EC系列介绍
871EC型无极电导率传感器与各种支持的传感器附件一起，可在大多数类型的过程液体中提供抗污垢测量。由于无电极技术和创新的传感器设计，将实现多年的连续运行和有意义的溶液电导率指示。
871EC传感器可与875EC智能分析仪，870ITEC智能变送器，873EC和873AEC分析仪以及870EC变送器一起使用。传感器有多种配置和适合各种条件的材料。
传感器测量溶液回路中的感应电流。他们获得专利的专利设计包括封装在传感器中的两个或三个环形缠绕线圈，这些线圈浸没在溶液中。 施加到一个环形线圈的交流信号在第二个线圈中感应出一个电流，该电流与溶液的电导率成正比。
The Model 871EC Electrodeless Conductivity Sensors, in conjunction with a variety of supporting sensor accessories, provide fouling-resistant measurements in most types of process liquids. Because of the electrodeless technique and innovative sensor design, years of continuous operation and meaningful indication of solution conductivity will be realized.
The 871EC Sensors are used with 875EC Intelligent Analyzers, 870ITEC Intelligent Transmitters, 873EC and 873AEC Analyzers, and 870EC Transmitters. Sensors are available in a number of configurations and materials suitable for a variety of conditions.
The sensors measure an induced current in a loop of solution. Their patented proprietary design comprises two or three toroidally wound coils encapsulated within the sensor which is immersed in the solution. An ac signal, applied to one toroidal coil, induces a current in the second coil that is directly proportional to the conductance of the solution.
