影響壓力開關(guān)的因素
壓力開關(guān)在使用過程中，振動、沖擊、過程溫度和超壓都會降低壓力開關(guān)的壽命，為了可以使壓力開關(guān)的壽命可以更久，我們應(yīng)當(dāng)了解哪些因素會影響壓力開關(guān)的壽命，從而更好的維護(hù)壓力開關(guān)。
1.需測量的介質(zhì)不可對壓力開關(guān)的膜片造成影響，因?yàn)檫B接膜片是精密的感壓元件，絕對不可用硬物刺探。
2.務(wù)必在選型表耐壓范圍內(nèi)使用，否則過壓會造成壓力開關(guān)的損壞。
3.為了避免損害壓力開關(guān)的器件，嚴(yán)格按照選型表上規(guī)定的電壓電流范圍使用，耐壓和最高溫度不能超過允許的范圍。
4.在潮濕的環(huán)境中要將壓力開關(guān)的入口點(diǎn)密封起來防止?jié)駳獾倪M(jìn)入。
5.定期對壓力開關(guān)進(jìn)行校驗(yàn)，確保壓力開關(guān)動作準(zhǔn)確。
