The explosion-proof baffle type flow switch is suitable for the switch of supporting mechanical equipment, pressure vessel, cut-off and idling protection.
Explosion-proof flow switches are mainly used to automatically protect equipment and pipeline systems from damage caused by flow reduction or cut-off; they are widely installed in flammable and explosive places such as oil and gas pipelines and refineries. The unique magnetic action switch design of the explosion-proof flow switch provides excellent working performance. It does not contain bellows and other components that are likely to cause failure, so that the explosion-proof flow switch has stable performance and timely action.
Ordinary baffle type flow switch double contact setting explosion-proof flow switch
Normally closed (N.C) contact setting method
Normally closed point means that when there is no flow or the flow is low, the switch is closed, and it opens only when the flow increases to a certain value. The plastic rod moves in the direction of the water flow to increase the flow setting value, and the plastic rod moves in the opposite direction of the water flow.
Normally open (N.O) contact setting method
Normally open point means that when there is no flow or the flow is low, the switch is open, and it is closed only when the flow increases to a certain value. The plastic rod moves in the direction of the water flow to increase the flow rate setting, and the plastic rod moves in the opposite direction of the water flow to decrease the flow rate.
