POTTER壓力開關PS40-EX產品介紹
Potter PS40-EX監(jiān)控壓力致動開關主要用于檢測位于上述危險位置的自動噴水滅火系統(tǒng)中正常系統(tǒng)壓力的升高和/或降低。典型應用包括：干管系統(tǒng)，預作用空氣/氮氣監(jiān)控，壓力罐，空氣和水供應。 PS40-EX開關出廠設置為正常系統(tǒng)壓力為40 PSI（2.8 BAR）。標有LOW字樣的開關設置為在30 PSI（2.1 BAR）的壓力降低10 PSI（7 BAR）時運行。標有“ HIGH”字樣的開關設置為在50 PSI（3.5 BAR）的壓力增加10 PSI（7 BAR）時運行。
The Potter PS40-EX Supervisory Pressure Actuated Switch is designed primarily to detect an increase and/or decrease from normal system pressure in automatic fire sprinkler systems located in hazardous locations classified as shown above. Typical applications are: Dry pipe systems, pre-action air/nitrogen supervision, pressure tanks, air supplies, and water supplies. The PS40-EX switch is factory set for 40 PSI (2,8 BAR) normal system pressure. The switch marked with the word LOW is set to operate at a pressure decrease of 10 PSI (7 BAR) at 30 PSI (2,1 BAR). The switch marked with the word HIGH is set to operate at a pressure increase of 10 PSI (7 BAR) at 50 PSI (3,5 BAR).
