FOXBORO PH/ORP传感器871A系列介绍

871A-1和-2（标准）传感器设计用于873PH和873DPX分析仪，也可以与875PH分析仪和870ITPH变送器一起使用。

871A-3和-4（智能）传感器设计用于875PH智能分析仪和870ITPH智能变送器。它们提供了在线诊断的附加功能，以在出现几种常见传感器故障中的任何一种时向用户发出信号。这些传感器可以通过多种方式安装到过程中。它们在电极和电缆末端都有1英寸的外部NPT连接。传感器可以直接插入到生产线中，也可以通过各种附件将传感器连接到其他标准管道尺寸。通过将传感器电缆端的1英寸NPT连接耦合到所需长度的1英寸管道，然后将组件降低到要监视的过程中，就可以在堰，水渠，池塘和水箱中进行现场安装。

这些传感器采用密封的电极设计，消除了对电极系统完整性的担忧。当与智能分析仪或变送器一起使用时，智能传感器设计可以向用户发送信号，告知其电极系统完整性是否丢失或破坏。所有传感器均经过工厂测试，以确保安装时具有适当的性能。

The 871A-1 and -2 (standard) Sensors are designed for use with 873PH and 873DPX Analyzers.They can also be used with 875PH Analyzers and 870ITPH Transmitters.

871A-3 and -4 (intelligent) Sensors are designed for use with 875PH Intelligent Analyzers and 870ITPH Intelligent Transmitters. They provide the additional capability of on-line diagnostics to signal the user if any of several common sensor faults occur. These sensors may be mounted to the process in a number of ways. They have a 1-inch external NPT connection on both the electrode and cable end. The sensors can be inserted directly into the process line or through a variety of accessories that adapt this connection to other standard pipe sizes. In-situ mounting into weirs, flumes, ponds and tanks is achieved by coupling the 1-inch NPT connection at the cable end of the sensor to the required length of 1-inch pipe and then lowering the assembly into the process being monitored.

These sensors, with their sealed electrode design, eliminate concerns of electrode system integrity.The intelligent sensor design, when used with the intelligent analyzer or transmitter, signals the user if electrode system integrity is lost or destroyed. All sensors are factory tested to ensure proper performance upon installation.
