AEROSONIC 55035-0103-23, Cabin Altitude Pressure Indicator, Used

Description:

The Aerosonic 55035-0103-23 is a dual-function cabin altitude and differential pressure indicator designed for pressurized aircraft. It provides critical real-time monitoring of the aircraft's internal environment compared to the outside atmospheric pressure.
Dual-Function Display: Features two independent mechanisms to display both Cabin Altitude (inner/outer scale in feet) and Differential Pressure (inner scale in PSI).
Alternate Part Numbers: Often cross-referenced as 50-380046-23.
Physical Design: Typically features a 2-inch or 3-inch round or ATI-style case.
Typical Weight: Standard models in this series weigh approximately 1.0 lb.
Lighting Options: Available with various lighting configurations, including 5V or 28V, and blue, white, or NVIS (Night Vision) compatibility.
Aircraft Type: Commonly used in pressurized twin-turboprop and light jet aircraft, such as the Beechcraft King Air and Sabreliner series.
Purpose: Essential for alert systems that notify the flight crew of excessive cabin altitude or a loss of pressurization, preventing pilot hypoxia.
