( Brand: Plessey ), ( Manufacturer Part Number: 754-1130307 ), ( Part Type: Pressure Switch )
The Plessey 754-1130307 Aircraft Pressure Switch is a critical component in aviation systems, designed to monitor and control pressurized fluid systems in aircraft. This pressure switch is engineered with precision and reliability in mind, making it a trusted choice for both commercial and military aircraft.
The switch features a robust, anodized aluminum housing, providing excellent resistance to corrosion and ensuring long-term durability even in harsh environmental conditions. The housing is designed with a threaded connection, allowing for easy installation and removal, while the pressure port is equipped with a screw-on cap for additional protection.
The 754-1130307 pressure switch operates on a simple yet effective principle, using a diaphragm that senses changes in pressure. When the pressure inside the switch exceeds or falls below the pre-set limits, the diaphragm moves, actuating a contact inside the switch, which in turn triggers a response in the aircraft's systems.
The switch is rated for operating pressures ranging from 0.6 to 6.9 bar (gauge), making it suitable for a wide variety of aircraft systems, including fuel, hydraulic, and pneumatic systems. It also features a switch contact rating of 2A at 28VDC, ensuring reliable operation even under heavy load conditions.
The Plessey 754-1130307 Aircraft Pressure Switch is also designed with safety in mind. It features a fail-safe mechanism that ensures the switch returns to its normal position if the pressure exceeds the safe operating limit, protecting the aircraft's systems from damage.
In summary, the Plessey 754-1130307 Aircraft Pressure Switch is a high-quality, reliable, and versatile component, essential for maintaining the safety and functionality of aircraft pressure systems. Its robust design, wide operating pressure range, and fail-safe mechanism make it an excellent choice for aviation professionals.
