型号描述
Bürkert 8222 型设备是一个用于测量液体电导率的紧凑型传送器。传送器 8222 装配有一个传感器。该传感器被一个销钉固定在外壳上，不可拆卸。含有电子设备模块及可拆卸指示器的外壳，装配有一个盖子。传感器本身具有三个不同的单元常数 C，由一个温度探测器 Pt1000 和两个电导率电极构成。在常数 C 为 0.01 或 0.1 时，传感器由不锈钢构成，而在常数 C 为 1.0 时，由石墨构成。利用一个锁紧螺母将单元固定在工序中。仅在调试、配置和校准时或者作为工艺值指示器使用时，才需要可选指示器。8222 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。型号 8222 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）模拟的 4-20 mA 输出端
2）带有锁紧螺母的通用过程接口
3）三种不同的电导率传感器，适合较宽的测量范围
4）温度补偿测量
Type Description
The Bürkert Type 8222 is a compact device designed for measuring the conductivity of fluids. The transmitter consists of a sensor, pluggedin and pined to an enclosure with cover, containing the the electronic module and a 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 transmitter can operate independant of the display but it will be required for programming the transmitter (i.e. selection of sensor cell constant, language, measuring range, engineering units, calibration...) 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 electronics of Type 8222 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）Analog 4-20 mA output
2）Universal process connection
3）Three cell constants for covering a wide measuring range
4）Temperature compensated measurement
