Aircraft Sensors and Systems Advances in sensing technologies and electronics have enabled AMETEK Aerospace & Defense to develop a highly reliable solid state pressure switch with excellent accuracy. The switch employs AMETEK Silicon-on-Insulator (SOI) sensor with the patent-pending field shield along with proprietary compensation/switching circuitry to ensure unsurpassed long cycle life with virtually no calibration drift. The performance and stability of AMETEK’s SOI sensor has been demonstrated through rigorous testing and validated by exceptional performance and reliability in aerospace and military applications. The all welded, stainless steel construction and ruggedized electronics packaging provide a robust design capable of withstanding the most demanding operating environments. With no moving parts, the solid state design is immune from the damaging effects of shock and vibration. Real-time compensation is used for increased accuracy over a wide temperature range. To ensure proper operation in any environment, the compensation electronics are filtered to reduce emission of and mitigate the susceptibility to RF noise. The switch meets or exceeds the environmental requirements of RTCA/ DO-160 and MIL-STD-810 and the EMC requirements of RTCA/DO-160 and FEATURES y Solid state construction with unsurpassed reliability y Accurate over a wide temperature range y Adjustable hysteresis y Modular design allows for quick customization y Optional multiple switch points MIL-STD-461. A modular design allows for a wide range of configurations. Available in pressure that ranges from 0 to 6000 psi (0-400 bar) the switch can be customize to provide a highly reliable and accurate “drop-in” replacement for existing mechanical switches. AMETEK Aerospace & Defense has built a reputation for supplying innovative pressure products for the aviation and military industry. The solid state pressure switch provides rugged reliability and intelligent design that takes advantage of the latest developments in electronics. AEROSPACE & DEFENSE
