FBM202 FOXBORO DCS控制系统 福克斯波罗控制器

Foxboro接触电导率和电阻率产品系列包括传感器、分析仪和变送器。传感器类型包括871CC和871CR，两者都有.1和1.cm的电池常数。

传感器的特点是的安装附件，的结构，坚固的设计和易于使用。分析仪包括875CR和873系列。这些是带有测量显示、报警触点和模拟输出的线动力仪器。发射机是876CR，这是一个环路供电，两线发射机与4到2毫安输出和HART通信。

为保证高精度，本组件每个通道采用一个Sigma-Delta数据转换，每25毫秒扫描一次，并且可组态移动的平均滤波器可去除任何过程噪声和电源线。安装在面板上的发光二极管LED指示了现场总线组件工作状态。

The Foxboro contact conductivity and resistivity product line includes sensors, analyzers and transmitters. Sensor types include 871CC and 871CR, both of which have battery constants of.1 and 1.cm.

The sensor is characterized by mounting accessories, construction, rugged design and ease of use. Analyzers include the 875CR and 873 series. These are linear power instruments with measurement displays, alarm contacts, and analog outputs. The transmitter is 876CR, which is a loop-powered, two-wire transmitter with 4 to 2 mah output and HART communication.

To ensure high accuracy, this component uses a Sigma-Delta data conversion per channel, scanned every 25 milliseconds, and a configurable mobile-averaging filter removes any process noise and power lines. A light-emitting diode LED mounted on the panel indicates the operating status of the fieldbus components.
