內(nèi)部開關(guān)機(jī)構(gòu)具有密封的金交叉點觸點，可實現(xiàn)可靠的低電流操作。常見應(yīng)用包括：報警撥號器、泵控制器、SCADA 系統(tǒng)、本質(zhì)安全屏障、太陽能應(yīng)用以及其他低電流控制和報警應(yīng)用。

滿足您需求的型號

我們?yōu)楦呒墤?yīng)用提供常開 (NO) 型號。該型號的控制開關(guān)在浮子在水平上方 45 度處發(fā)出高電平信號時打開（關(guān)閉），在浮子下降到水平以下 45 度時關(guān)閉（打開）。我們還為低級應(yīng)用提供常閉 (NC) 型號。該型號的控制開關(guān)在浮子下降到水平線以下 45 度時打開（關(guān)閉），發(fā)出低電平信號，當(dāng)浮子傾斜到水平線以上 45 度時關(guān)閉（打開）。

英文原文：

The WA170 Mechanical Float Switch offers a reliable low current control for AC and DC applications in potable water, wastewater, and sewage.

Overview

FEATURES

? Mechanically activated, snap action contacts

? High impact, corrosion resistant polypropylene float housing

? Low current, non-arcing applications

? UL Listed for use in non-potable water and sewage

? CSA Certified

The internal switching mechanism has sealed gold cross-point contacts for reliable low current operation. Common applications include: alarm dialers, pump controllers, SCADA systems, intrinsically safe barriers, solar applications, and other low current control and alarm applications.

Models to Meet Your Needs

We offer a Normally Open (NO) model for high level applications. This model's control switch turns on (closes) when the float tips 45 degrees above horizontal signaling a high level, and turns off (opens) when the float drops 45 degrees below horizontal. We also offer a Normally Closed (NC) Model for low level applications. This model's control switch turns on (closes) when the float drops 45 degrees below horizontal signaling a low level, and turns off (opens) when the float tips 45 degrees above horizontal.
