FS-10798 Series Flow Switch
外部可调型流量开关，适用于水，油和气体
优势...
- 流速设置: 液体 - 从0.5GPM 到20.0GPM; 气体- 见下表
- 接口: 1/2" NPT
- 主要结构材质: 黄铜或不锈钢
- 设置类型: 可调式
概述 / 设计理念:
这类外部可调型流量开关是下列应用的理想选择：在冷却液流量故障时保护机床设备；在润滑剂较少时保护轴承；或确保适当的空气流量。FS-10798 系列产品
工作压力高达1000PSIG, 具有很宽的流量设置范围，同时具有极低的压损和极高的重复性。
采用－普通的平头螺丝刀，就可很方便到进行现场调节。现场校准后，为防止擅自改动，可将调节部分用螺丝锁紧。应用:
- 电子设备: Laser Heads, Welders, Power Supplies, High Speed Spindles, X-Ray Tubes, Semiconductor Equipment
- 齿轮和轴承: Presses, Rotating Equipment, Conveyors, Machine Tools, Robotics
- Processing & Dispensing Equipment: Water Purifications and Filtering, X-Ray Film Processing, Beverage Dispensing, Chemical Additives, Gas Sampling, Distilling

Air/Gas Flow Adjustment Ranges
Water or oil flow units should not be utilized for air/gas applications. The FS-10798 Gas Flow configuration utilizes special dash-pot piston for reliability. The flow adjustment ranges are typical for air service. For other gases, the flow range will vary with the density of the gas. Please consult factory for more information.
For 5 PSIG Line* 1 to 75 SCFM Approx.
For 100 PSIG Line 3 to 160 SCFM Approx.
*Minimum 5 PSI line pressure required.
FS-10798 switches are U.L. Approved for Class I, Division 2, Groups A, B, C, D hazardous locations.
