FS-10798 Series Flow Switch
外部可調(diào)型流量開關(guān)，適用于水，油和氣體
優(yōu)勢...
- 流速設(shè)置: 液體 - 從0.5GPM 到20.0GPM; 氣體- 見下表
- 接口: 1/2" NPT
- 主要結(jié)構(gòu)材質(zhì): 黃銅或不銹鋼
- 設(shè)置類型: 可調(diào)式
概述 / 設(shè)計理念:
這類外部可調(diào)型流量開關(guān)是下列應(yīng)用的理想選擇：在冷卻液流量故障時保護機床設(shè)備；在潤滑劑較少時保護軸承；或確保適當(dāng)?shù)目諝饬髁?。FS-10798 系列產(chǎn)品
工作壓力高達1000PSIG, 具有很寬的流量設(shè)置范圍，同時具有極低的壓損和的重復(fù)性。
采用－普通的平頭螺絲刀，就可很方便到進行現(xiàn)場調(diào)節(jié)?，F(xiàn)場校準后，為防止擅自改動，可將調(diào)節(jié)部分用螺絲鎖緊。應(yīng)用:
- 電子設(shè)備: Laser Heads, Welders, Power Supplies, High Speed Spindles, X-Ray Tubes, Semiconductor Equipment
- 齒輪和軸承: 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.
