POTTER 防爆壓力開關(guān)PS25-2產(chǎn)品介紹
The Potter PS25 Series Supervisory Pressure Actuated Switches are designed primarily to detect an increase and/or decrease from normal system pressure in automatic fire sprinkler systems. Typical applications are: air/nitrogen supervision in dry pipe and pre-action systems, pressure tanks, air supplies, and water supplies. The PS25-2 has two switches. The Low switch is factory set to activate at approximately 18 psi (1,2 BAR) on a decrease in pressure. The High switch is factory set to activate at approximately 28 psi (1,9 BAR) on an increase in pressure. NFPA 72 requires a supervisory signal for both high and low pressure conditions. The PS25 is factory set for a normal air pressure of 23 psi.
POTTER PS25系列監(jiān)控壓力致動開關(guān)主要用于檢測自動消防灑水系統(tǒng)中正常系統(tǒng)壓力的增加和/或減少。典型應(yīng)用包括：干管和預(yù)作用系統(tǒng)中的空氣/氮?dú)獗O(jiān)控，壓力罐，空氣供應(yīng)和水供應(yīng)。PS25-2有兩個開關(guān)。低壓開關(guān)出廠設(shè)置為在壓力降低時以約18 psi（1,2 BAR）的速度激活。高壓力開關(guān)出廠設(shè)置為在壓力升高時以約28 psi（1.9 BAR）的速度激活。NFPA 72需要高壓和低壓條件下的監(jiān)控信號。PS25出廠設(shè)置為23 psi的正常氣壓。
