FS-925 系列流量开关
通用
特性...
- 流量设置:液体0.1GPM至1.50GPM;空气/气体-见下页的流量设置
- 接口:1/4"NPT
- 主要结构材质:黄铜或不锈钢
- 设置类型:固定式
概述/设计原理:
该系列的精密校准开关提供了可靠和一致的性能;其测量重复性在1%内。FS-925产品应用在特殊流速时需在出厂时设置动作点.
这些开关在下列应用中对流速过大或不足提供了精确的监测:在液压系统中防止流量不足、在半导体工艺设备中确保适当的冷却剂流量、监控高压润滑系统以及在水/废水处理系统中确保适当的空气流量.
应用:
- 机电设备:激光头,焊接机,电源供应器,高速主轴,X射线管,半导体设备
- 轴承与齿轮:压力机,旋转设备,输送机,机床,机器人
- 处理与分装设备:水纯化与过滤,X光片加工,饮料分装,化学添加剂,气体取样,蒸馏机

Gas Calibration
Water flow units should not be used for air/gas applications: Gas flow units have a special dash-pot piston for reliable operation. Gas calibration is dependent upon line pressure, switch orientation, and the specific type of gas. The calibrated flow set point is subject to change with fluctuations in line pressure.
