Double Pressure Switch Danfoss KP15
The Danfoss KP15 060-124166 dual pressure switch is a device designed to control pressure in refrigeration and air conditioning systems. Its purpose is to monitor system pressure and safeguard against undesirable pressure levels, protecting the compressor and other system components from damage.
Features and Applications:
- Pressure Monitoring: Enables simultaneous monitoring of low and high pressures in the refrigeration system.
- System Protection: Prevents the compressor from operating under conditions of excessively low or high pressure. An automatic reset allows the system to restart once pressure returns to normal levels.
- Device Control: Can be used to switch compressors, fans, or other components on or off in response to pressure changes.
- Applications: Suitable for refrigeration and air conditioning systems, particularly those requiring precise pressure control.
Construction of the KP15 Pressure Switch:
The KP15 houses two independent control circuits—for low and high pressure—within a single corrosion- and impact-resistant plastic enclosure. Pressure connections are made of brass or stainless steel. The adjustment mechanism, consisting of screws, allows precise pressure settings at which the switch activates. The electrical outputs feature SPDT (Single Pole Double Throw) contacts, facilitating connections to control circuits.
Operating Principle:
- Low-Pressure Operation: When system pressure drops below the set minimum level, the pressure switch disconnects the electrical circuit, shutting off the compressor or other device.
- High-Pressure Operation: When pressure exceeds the set maximum level, the switch interrupts the circuit, halting system operation.
- Reset: The built-in auto-reset mechanism automatically restores the circuit connection when pressure returns to a safe range.
- Adjustment: The KP15 allows manual setting of cut-off values for both low and high pressure.
Advantages of Danfoss KP15:
- Safety: Protects the system from damage caused by extreme pressure levels.
- Ease of Installation: Compact design and universal connectors simplify installation.
- Automatic Operation: The auto-reset function eliminates the need for manual resets, enhancing convenience.
- Versatility: Suitable for a wide range of refrigeration and air conditioning applications.
Summary:
The Danfoss KP15 is a reliable dual pressure switch with an automatic reset function, ideal for modern refrigeration and air conditioning systems. By simultaneously monitoring low and high pressures and featuring built-in safety mechanisms, this device ensures the safety and efficiency of refrigeration systems.
