Pressure Sensors, Transducers

PX3AN1BH008BSAAX is a pressure sensor/transducer designed and manufactured by Honeywell Aerospace. It consists of a airframe mounted pressure sensing diaphragm and a signal conditioning unit which receives the signal from the diaphragm, converts it into an electrical signal, and amplifies it.

The PX3AN1BH008BSAAX is designed for use in aircraft systems for a wide range of applications, including cabin pressure monitoring, engine pressure monitoring, and fuel tank pressure measurement. It is capable of measuring pressure up to 5 psi (0.34 bar). The pressure sensing diaphragm is compliant with Federal Aviation Administration (FAA) requirements and is sealed to withstand both static and dynamic pressures. The signal conditioning unit features a frequency-compensated amplifier and high-impedance circuitry which eliminates the need for an external power supply.

The working principle of the PX3AN1BH008BSAAX is based on Piezoresistive Technology. Piezoresistive Technology makes use of the piezoresistive effect, which is a change in resistance that occurs in a certain material when a force is applied to it. In the case of the PX3AN1BH008BSAAX, a piezoresistive polysilicon strain gauge is attached to the silicon diaphragm, which generates a small voltage in response to applied pressure. This voltage is then amplified and conditioned by the signal conditioning unit and converted into an electrical output. The output from the pressure sensor is then transmitted to an aircraft system for monitoring or control purposes.

The PX3AN1BH008BSAAX is designed for a wide range of applications, including but not limited to airframe mounted pressure sensing systems, cabin pressure monitoring, engine pressure monitoring, and fuel tank pressure measurement. It is designed for operation in harsh environments and is capable of measuring pressure up to 5 psi (0.34 bar). The unit is compliant with FAA requirements and is sealed to withstand static and dynamic pressures. It features a frequency-compensated amplifier and high-impedance circuitry which eliminates the need for an external power supply. Finally, the PX3AN1BH008BSAAX utilizes Piezoresistive Technology to measure pressure and convert it into an electrical output.
