Dwyer DX液用差壓開關
DX是一種不同的壓力開關，它根據(jù)的是一個接觸輸出兩個壓力源之間的差值。
黃銅和flouro彈性體的浸濕材料適用于大多數(shù)氣體和水性溶液。
該開關可用于低差壓指示，設置點降低壓力低至1 psid(0.07 bar)。
差壓差和1.0至67 psid(0.07到4.62 bar)的差壓差值為2.5 ~ 75 psid(0.17 ~ 5.17 bar)。
單位特征為高靜態(tài)壓力等級200 psig(13.8 bar)。
防風雨，UL型4X 外殼 ，或沖洗安裝環(huán)境。外部可調(diào)設置點,
整體式安裝法蘭和可拆卸的電氣接線板，便于安裝。
