壓力開關的外觀與性能檢測
1.外觀檢測
用戶在進行壓力開關的外觀檢測時，主要包括以下幾方面內容：依據產品圖使用量具測量壓力開關的外形尺寸、檢查壓力開關的電鍍層和化學處理層是否達到國家要求。
2.電纜檢測
使用萬用表，測量壓力開關接線端之間及接線端與外殼間的絕緣電阻。并在可靠接通狀態下，檢查壓力開關與設備之間的連接是否完好，確保無短路、斷路的情況。
3.誤差試驗
將壓力開關安裝在試驗臺上，緩慢加壓（或減壓）后測定其開關起始壓力值；接著加壓（或減壓）到額定壓力值后，慢慢減壓（或加壓），測量其開關起始壓力值。
4.耐溫試驗
將壓力開關直接放入高溫或低溫環境中，觀察其是否能進行正常測量。
5.耐震試驗
將壓力開關置于振動幅度較大的場合中，查看其是否牢固可靠，并檢查其是否能正常進行測量工作。
