This instrument uses an aneroid capsule assembly to measure the atmospheric pressure outside of an aircraft. The pressure at a given altitude is a function of the air supported above that point where the force is caused by gravity. As the column of air is taller closer to earth, there is more pressure.
The aneroid capsule assembly has a deep vacuum trapped inside, and measures the difference between the atmosphere outside of the assembly and this nearly perfect vacuum. The internal vacuum is constant and provides the reference pressure that the capsule uses to measure altitude. Note the collapsed condition of the altitude capsule compared to the airspeed capsule.
Kearflex manufactures complex assemblies that are based upon our capsule sub-assemblies. These are sold to our customers to allow efficient installation in the next level assembly. Advantages to this approach are a "turn-key" product where the capsule related problems are solved and specialty manufacturing is performed.
Kearflex incorporates our diaphragms and capsule assemblies into altitude switches. In the altitude switch, the sensing element has a permanent vacuum trapped inside to allow the switch to respond to atmospheric pressure. Kearflex integrates our diaphragms and capsule assemblies into airspeed switches.
Mechanical movements amplify the displacement of the diaphragm to turn a pointer providing pressure indication. Using the small 1.125 inch diameter diaphragm, this mechanical gauge can be calibrated in ranges from 10 Psi to 400 Psi. A range of diaphragms is used providing the same deflection at the specified full scale pressure.
