Baffle explosion-proof flow switch NK01BS-RS

Principle Characteristics

Baffle flow switch is mainly an explosion-proof flow switch designed for industrial explosion-proof area. It is suitable for when the flow rate exceeds the set value, the fluid pushes the baffle and drives the micro switch on the top through the mechanical device in the flow switch.

Product Application

Gas-liquid dual type, fire protection industry/chemical industry/industrial automation/mechanical equipment/smelting equipment/hydraulic lubrication equipment.
