手册的重压力控制

Product characteristics: * Adopts Eng. thread quick connector (copper flare connection) or brass tube (including capillary) welding connecting structure; easy to mount for different needs * Board-assembly (with mounting ears) or wire-assembly (no need for separate fixing) can be chosen for outer shell assembly * The air-tight bi-security disc and stainless steel sensor ensure that the switch opens instantly automatically under the pressure and cuts off the connection between the switch contact and the pressure inside the system; the system will not be able to start up the machine by accidentally actuating the pressure switch, which is safe and reliable enough to prevent the machine from damaging * The independent structure design of auto switching off and manual resetting enhances the maximum security and stability for the pressure protection Applications: The series of switches are used to all air conditioning and refrigeration systems that require special pressure protection and broad range of extra-high pressure protection for the pressure systems of a variety of tools and equipment. They can be directly installed on the pipelines or on the control panels based on the equipment's situation. Designed parameters: * Working pressure range: 145PSI 700PSI (1.0MPa 4.8MPa) * Burst pressure: 5,000PSI * Ambient temperature: -30°C +80°C * System medium temperature: -50°C +120°C * Electrical rating: At 24V AC, normal electric capacity: 125VA At 120 / 240V AC, normal electric capacity: 375VA * Dielectric strength: Between disconnected contacts: AC 700V/s Terminal to outer shell: AC 2,000V/s Packing: Carton or pallet
