8222型电导率传送器 德国burkert

类型描述

Bürkert 8222 型设备是一种用于测量液体电导率的紧凑型测量仪。电导率测量仪装配有一个传感器。该传感器通过一根销钉固定在变送器上，变送器配有可拆卸式显示器。传感器本身具有三种不同的电池常数 C，传感器中包含一个温度感应器 Pt1000 和两个电导率电极。电池常数 C 为 0.01 或 0.1 的传感器，其电极由不锈钢制成；电池常数 C 为 1.0 的传感器，电极则为石墨材质。选配的显示器只有在调试、配置和校准或显示过程值时才会用到。8222 型设备有以下规格可供选择：- 配备三个可编程的输出端：两个晶体管输出端和一个两线制 4 ~ 20 mA 电流输出端- 配备四个可编程的输出端：两个晶体管输出端和两个三线制 4 ~ 20 mA 电流输出端。变送器转换测量信号、显示不同测量单元中的各个测量值（插入显示器时）并计算输出信号，计算出的输出信号通过一个或两个 M12 插头连接进行传输。

Type 8222 - Conductivity meter

Type Description

The Bürkert compact meter Type 8222 is designed for measuring the conductivity of fluids. The conductivity meter consists of a sensor, plugged-in and pined to the transmitter (with removable display). The sensor comprises a cell with two electrodes and a Pt1000 temperature probe. The sensor itself is available with three different cell constants C, these with C=0.01 or 0.1 are fitted with stainless steel electrodes and those with C=1.0 are fitted with graphite electrodes. The conductivity meter can operate independent of the display but it will be required for programming the device and also for visualizing continuously the measured and processed data. The device Type 8222 is available: - with three fully programmable outputs: two transistor and one 2-wire 4...20 mA current outputs - with four fully programmable outputs: two transistor and two 3-wire 4...20 mA current outputs. The transmitter converts the measured signal, displays different values in different physical units (if display mounted) and computes the output signals, which are provided via one or two M12 fixed connectors.

（1）Perfect for clean water and slightly concentrated liquids

（2）Integral device for direct connection to PLC

（3）Simulation of process values for diagnostics

（4）Three cell constants to cover a wide application range e.g. reverse osmosis
