PS11 系列壓力開關(guān) 

超長(zhǎng)壽命壓力開關(guān) 
 

特性... 

• 原PDPA/PDPF型號(hào) 
• 0.75到15psi (57.71到1034 mbar) 
• 典型壽命為一百萬(wàn)次周期
• 工廠設(shè)定或現(xiàn)場(chǎng)可調(diào) 

概述/設(shè)計(jì)原理: 

     PS11系列長(zhǎng)壽命壓力開關(guān)在于低壓應(yīng)用領(lǐng)域具有無(wú)可比擬的優(yōu)勢(shì)，一百萬(wàn)次周期意味著開關(guān)具有長(zhǎng)期的穩(wěn)定性。其微動(dòng)開關(guān)自動(dòng)快速?gòu)?fù)位可滿足超工業(yè)標(biāo)準(zhǔn)的需求。黃銅外殼使得開關(guān)具有很好的化學(xué)穩(wěn)定性，同時(shí)價(jià)格經(jīng)濟(jì).
