POTTER 防爆压力开关PS25-2产品介绍
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系列监控压力致动开关主要用于检测自动消防洒水系统中正常系统压力的增加和/或减少。典型应用包括：干管和预作用系统中的空气/氮气监控，压力罐，空气供应和水供应。PS25-2有两个开关。低压开关出厂设置为在压力降低时以约18 psi（1,2 BAR）的速度激活。高压力开关出厂设置为在压力升高时以约28 psi（1.9 BAR）的速度激活。NFPA 72需要高压和低压条件下的监控信号。PS25出厂设置为23 psi的正常气压。
