8202型pH 或氧化还原电位传送器 burkert

类型描述

Bürkert 生产的 8202 型设备是一款紧凑型的模块化测量仪，用于测量 pH 值或氧化还原电位 (ORP)：- pH 值：在干净、脏污或含有硫化物或蛋白质的液体中。- 氧化还原电位 (ORP)：在干净、脏污或含有硫化物或蛋白质的液体，以及电导率低的液体中。该设备包含一个 pH 探头或氧化还原探头，它拧在一个集成有 Pt1000 的传感器组件中。该结构件内置在外壳中，用一枚锁紧螺母固定。外壳配有盖子，它将电子模块（包括可拆卸式操作单元）包裹起来。Bürkert 通过这种设计简化了安装和维护工作。显示器只有在调试、配置、校准或显示过程值时才会用到。8202 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。 8202 型设备转换测量信号、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。

（1）集成式紧凑型测量仪，直接连接在控制层面上 (PLC)

（2）通过模块化的 HMI，对参数数据进行参数化设置、校准以及传输

（3）使用 120 mm 的标准型 PG13.5 ph 值/氧化还原探头，带 S8 接口。（推荐使用 8203 型设备）

（4）模拟过程值和诊断功能

（5）诊断功能

 

Type 8202 - pH/ORP meter

Type Description

The Bürkert Type 8202 is a compact, but modular device, specially designed for measuring the pH or ORP value of fluids. Our device consists of a replaceable standard 120 mm pH or ORP probe, screwed in a sensor holder with integrated Pt1000 temperature sensor. This ensemble is plugged-in and screwed with a nut to an IP67 enclosure containing the electronic module with cover and a removable display. Bürkert expedites thus maintenance work. The pH/ORP transmitter can operate independent of the display, but it will be required for programming the device (i.e. selection of pH or ORP sensor type, measuring range, engineering units...) and also for visualizing continuously the measured and processed data. The device Type 8202 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 device Type 8202 converts the measured signal, displays different values in different units (if display mounted) and computes the output signals, which are provided via one or two M12 fixed connectors.

（1）Integral compact measurement device for direct connection to control level (PLC)

（2）Thanks to the modular HMI, parameterization, calibration, transferring of （3）parameterization data easily possible

（4）Usage of 120 mm standard PG13,5 pH/ORP-probes with S8 connector (Type 8203 recommended)

（5）Simulation of process value and diagnostic function
