型号描述

Bürkert 8202 型设备，是一种用于测量 pH 值或氧化还原电位的紧凑型传送器：- pH 值：在洁净或脏污的或含有硫化物或蛋白质的液体中 - 氧化还原电位：在洁净或脏污的或含有硫化物或蛋白质的液体中以及电导率很小的液体中。传送器包含一个 pH 值或氧化还原电位探针，该探针被旋在带有集成式 Pt1000 的传感器配件中。该结构元件集成安装在外壳中，使用一个锁紧螺母固定。含有电子设备模块及可拆卸操作单元的外壳，装配有一个盖子。Bürkert 公司通过这种设计简化了安装和维护工作。仅在调试、配置和校准时或者作为工艺值指示器使用时，才需要指示器。8202 型设备是可用的：- 带有三个可编程的输出端：两个晶体管输出端和一个双线 4-20 mA 电流输出端 - 带有四个可编程的输出端：两个晶体管输出端和两个三线 4-20 mA 电流输出端。8202 型设备能够转换测量信号，以不同测量单位显示不同数值（如果已插接指示器）并计算通过一个或两个 M12 插拔连接器传输的输出信号。

1）可编程的输出端：两个晶体管以及一个或两个输出端 4-20 mA（过程 + 温度）
2）可拆除的指示器，带有背景照明装置
3）带有锁紧螺母的通用过程接口
4）与 pH/Redox 探针之间相互兼容，柄长 120 mm
5）诊断功能

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 parameterization data easily possible
3）Usage of 120 mm standard PG13,5 pH/ORP-probes with S8 connector (Type 8203 recommended)
4）Simulation of process value and diagnostic function
