The GB300-158 Barometric Switch, manufactured by Aerospace Controls, is a pneumatic pressure switch designed specifically for aviation and aerospace applications. This switch is engineered to meet the stringent requirements of the aerospace industry, ensuring reliability and precision in various flight control systems.
The GB300-158 Barometric Switch operates based on the changes in atmospheric pressure. It is a 2-position, 3-way, normally closed (NC) pneumatic switch, signifying that it is in the closed position when no pressure is applied. Upon reaching a specified pressure, the diaphragm inside the switch actuates, causing the internal valve to open, thus changing the flow of pneumatic media. This feature makes the switch ideal for sensing changes in pressure within fuel tanks, hydraulic systems, environmental control systems, and other crucial applications within an aircraft.
The GB300-158 Barometric Switch is constructed using high-quality materials, allowing it to withstand the extreme temperatures and pressures typically encountered in aerospace environments. The external casing is made from 303SS, offering excellent corrosion resistance, while the internal components consist of zinc-nickel-plated brass that provides robustness and superior wear resistance. Moreover, the switch's stem seal is made from a material that guarantees excellent sealing performance throughout the switch's operational life.
This aerospace-grade barometric switch features an adjustable set pressure range, enabling customers to customize the switch to suit the specific requirements of their applications. The set pressure can be configured between 14.3 psi (100 kPa) and 35.5 psi (248 kPa) using the provided 5-turn adjusting screw located on the side of the switch housing. Additionally, the GB300-158 Barometric Switch comes with a visible pressure indication, consisting of a red triangular capillary tube that becomes visible when the set pressure is reached.
The GB300-158 Barometric Switch from Aerospace Controls is designed to offer long-lasting performance in the demanding conditions that aerospace applications demand. Its rugged construction, combined with its versatility and precision, makes it the preferred choice for aviation applications, and its adjustability allows it to accommodate various system configurations. The switch's compact size, 3.7 inches (94.0 mm) long, 1.8 inches (46.0 mm) wide, and 2 inches (51.0 mm) high, makes it an excellent solution for tight installation spaces, further enhancing its versatility.
Overall, the GB300-158 Barometric Switch by Aerospace Controls is a reliable, high-performance, and versatile component for sensing atmospheric pressure changes in aerospace applications. Its stringent manufacturing, rigorous testing, and aerospace approvals, such as FAA AC 20-81 and SAE AS5623, ensure that it is a trusted solution for aviation engineers seeking exceptional reliability and precision.
