高溫環(huán)境如何保護(hù)壓力開關(guān)
當(dāng)壓力開關(guān)需要長(zhǎng)期處于高溫環(huán)境工作時(shí)，用戶一定要采取相對(duì)應(yīng)的措施保護(hù)壓力開關(guān)，否則就會(huì)嚴(yán)重?fù)p害壓力開關(guān)的內(nèi)部元件并且降低壓力開關(guān)的性能。
當(dāng)工作環(huán)境的溫度為中高溫時(shí)，只需在壓力開關(guān)的取壓連接處加裝一個(gè)散熱器，利用散熱器將中高溫逐漸降低，降低至壓力開關(guān)的適應(yīng)溫度；當(dāng)工作環(huán)境的溫度為高溫時(shí)，則需要采取兩個(gè)步驟進(jìn)行降溫：一是加裝一個(gè)冷凝裝置，將溫度進(jìn)行冷卻，二裝完冷凝裝置后再加裝散熱器實(shí)現(xiàn)雙重保護(hù)，讓高溫遠(yuǎn)離壓力開關(guān)。當(dāng)工作環(huán)境的溫度為超高溫時(shí)，就需要將導(dǎo)管延長(zhǎng)，再安裝毛細(xì)管，將超高溫的被測(cè)介質(zhì)遠(yuǎn)離壓力開關(guān)實(shí)現(xiàn)介質(zhì)冷卻的效果。
工作環(huán)境對(duì)壓力開關(guān)的影響是巨大的，除了上述的高溫環(huán)境，還有別的環(huán)境也會(huì)影響壓力開關(guān)，詳情可以閱讀：“壓力開關(guān)如何避免不良的工作環(huán)境”。
