NASON壓力開關(guān)技術(shù)分析，NASON壓力開關(guān)主要類別包括常開式和常閉式。美國NASON壓力開關(guān)的主要特點(diǎn)是:
1、采用英制管螺紋快速接頭或銅管焊接式安裝結(jié)構(gòu)，安裝靈活，使用方便，無需特殊的安裝固定。
2、插片式導(dǎo)線式連接方可供用戶任意選定。
3、密封式不銹鋼感應(yīng)器安全可靠。
4、壓力范圍內(nèi)可根據(jù)用戶任意選定的壓力值進(jìn)行制造。

經(jīng)濟(jì)，氣動(dòng)和九頭蛇
NASON壓力開關(guān)是一種簡單的壓力控制裝置，當(dāng)被測壓力達(dá)到額定值時(shí)，NASON壓力開關(guān)可發(fā)出警報(bào)或控制信號。納森壓力開關(guān)的工作原理是：當(dāng)被測壓力超過額定值時(shí)，彈性元件的自由端產(chǎn)生位移，直接或經(jīng)過比較后推動(dòng)開關(guān)元件，改變開關(guān)元件的通斷狀態(tài)，達(dá)到控制被測壓力的目的。
NASON液壓和氣動(dòng)壓力開關(guān)，Nason’s complete line of pressure switches offers design engineers a choice of low to high pressure switch models ranging from 2 PSI to 7500 PSI. Models are available for both pneumatic and hydraulic applications. All of Nason’s pressure switches use a snap-action electrical device activated by a precise, long-life elastomer diaphragm or piston offering a precise and repeatable design.NASON壓力開關(guān)技術(shù)分析
The snap-action design will maintain its state with contacts either open or closed, until a precise set point is reached when it will snap over center to a new state. It will remain in that state until a distinct change towards its original setting is sensed, at which time it will snap back to its original state. The design’s snap action feature prevents contact intermittency near its switch point, which is common in creepers.
As system pressures fluctuate, our switches inherent differential prevents searching. Nason uses only the highest quality snap action switches. These switches and Nason’s are UL, CSA, and military approved.
NASON壓力開關(guān)是與電器開關(guān)相結(jié)合的裝置，當(dāng)?shù)竭_(dá)預(yù)先設(shè)定的流體壓力時(shí)，開關(guān)接點(diǎn)動(dòng)作。主要應(yīng)用于電廠、石化、冶金行業(yè)等工業(yè)設(shè)備上輸出報(bào)警或控制信號，在工業(yè)領(lǐng)域中有著重要的用途，能預(yù)防生產(chǎn)工程中重要裝置的損壞，避免了重大生產(chǎn)事故地發(fā)生。
