POTTER壓力開關(guān)PS40-EX產(chǎn)品介紹
Potter PS40-EX監(jiān)控壓力致動開關(guān)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(guān)出廠設(shè)置為正常系統(tǒng)壓力為40 PSI（2.8 BAR）。標有LOW字樣的開關(guān)設(shè)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(guān)設(shè)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).
