8694型数字化电-气位置调节仪 德国burkert

类型描述

可一体化安装于气动控制工艺调节阀上的紧凑式位置调节仪。通过标准信号 4 至 20 mA 或 AS-Interface 规定额定值。非接触式工作的传感器元件测定阀门主轴的位置。 通过自动的调谐功能实现轻松调试以及利用 DIP 开关进行设置：密闭功能、特征曲线选择、工作方向逆转、手动/自动模式切换、二进制输入。利用设备 DTM 形成参数化附加选项。线性化工作特征曲线时，利用可自由编程的特征曲线，即可使用软件接口及其他接口。状态显示可通过 LED 灯实现。可选择一体化模拟位置反馈信息。

（1）紧凑耐用的不锈钢设计

（2）使用自动调谐功能进行调试

（3）非接触式行程吸收器

（4）一体化控制空气传输至驱动器中

（5）AS-Interface 现场总线接口（选项）

 

Type 8694 - Digital electropneumatic positioner for the integrated mounting on process control valves

Type Description

Compact positioner for integrated mounting on pneumatically operated process valves. Remote setpoint adjustment via a 4-20 mA signal or through AS-Interface. A contact-free analog position sensor measures the position of the valve spindle. Simple installation through automatic tune function and setting through DIP-switch: Close tight function, Characteristic curves selection, Reversal of effective direction, Switching manual /automatic operation, Binary input. Additional parametrisation options are possible through DTM devices. A software interface can be used for, amongst others, linearisation of the operation characteristics by using free programmable fixed points. The valve position indication is shown through LED components. As an option an analogue position feedback can be integrated.

（1）Compact, robust stainless Steel design

（2）Start-up by automatic Tune function

（3）Contact-free position sensor

（4）Integrated control air routing

（5）Fieldbus interface AS-Interface (option)
