Pressure switch is mainly used in ventilation and air conditioning systems to control the air flow in ventilation ducts, as well as in filters, fins and fans. Suitable for air and other non-flammable and non-aggressive gases. This switch is capable of sensing a slight change in pressure and is widely used to control the flow of the aerator, control and ventilation and air conditioning. It is also suitable for overheating and frost protection in industrial refrigeration systems. Thanks to its outstanding design, the set point can be adjusted visually Pressure connection: 6.2mm internal thread tube or G1/8 (optional if the hole is in hole) Electrical connection: AMP6.3mm screw terminal connector; AMP4.8mm connector Operating temperature: -30Celsius 85Celsius (overpressure 5000Pa) p Installation is and easy, both vertical and horizontal p Extremely high adjustment accuracy p Long service life and stable operation Suitable for medium: air, non-corrosive gas.
