Absolute pressure switch AV-1

atmosphericfor aircraft

Absolute pressure switches from Pressure Controls, Inc. are used in situations where changes in atmospheric pressure can affect the accuracy of the switch. By isolating the sensing element from exterior conditions, absolute pressure switches use zero PSIA as their reference point and provide a more accurate representation of any changes in pressure. Because of this, these switches can be completely submerged without affecting performance. Absolute pressure switches have excelled in these applications: Altitude Switches, SF6 Monitoring Switches and Custom / Harsh Environment Applications. Scroll down to learn more about each application and feel free to contact us directly with any questions that you may have. These switches are designed to open or close a circuit at a specific altitude. CRITICAL PARTS OUR CUSTOMERS RELY ON EVERY DAY Controlling functions automatically in the Aerospace Industry We've worked closely with partners in the aerospace industry, both in commercial and defense aviation applications. These switches have been deployed to activate or deactivate a circuit when the aircraft reaches the designed altitude. Adding safety to Military & Defense Applications We've also worked with the defense industry to develop altitude switches that act as safety interlocks and can monitor external as well as internal conditions aboard aircraft and projectiles. ALTITUDE SWITCHES DESIGNED SPECIFICALLY FOR YOUR NEEDS The AV-1 and SE-5 altitude switches have been in PCI's catalog for over 50 years and have become industry standards, but if your application requires a different set of specifications, please feel free to contact our team here.
