Pressure Sensors, Transducers

The PX3AF1BH010BSAAX pressure sensor (herein referred to as PX3) is used to measure the pressure in a wide range of applications. The PX3 is a digital sensor, based on capacitive measuring technology. It is available with pressure ranges from -150 mbar to 0 mbar, -30 mbar to +200 mbar, and -500 mbar to 0 mbar. The PX3 is available with either of two output types, an analog type (4-20mA output) and a digital type (I2C interface). The PX3 is also available in a range of package types.

Application Field

The PX3 has a variety of applications. It is suitable for applications where high accuracy and stability are required, such as in medical equipment, aircrafts, and automotive applications. It can also be used as a transmitter, sending an analog or digital signal to a controlling unit. The PX3 is used in a wide range of applications, such as in industrial process control, fluid measurement, and low-pressure applications. It is also suited for demanding applications, such as aerospace, nuclear, and military applications.

Working Principle

The PX3 is based on the principle of capacitive sensing, which uses two capacitors separated by a flexible membrane. The membrane is made up of a diaphragm and a pressure sensitive material, which deforms when the pressure is applied. The two capacitors measure the deflection of the membrane, which is proportional to the applied pressure. The deflection is directly proportional to the pressure applied, and the output of the PX3 accurately reflects the pressure applied to the membrane. This makes the PX3 an ideal device for measuring low pressure changes.

The PX3 is capable of measuring absolute, barometric and differential pressure. It has a high accuracy and is designed to measure low pressure changes with a low offset. It also features built-in temperature compensation, which helps to increase accuracy. The PX3 is designed for applications where low power consumption is critical, and it can operate on a supply voltage of 3.3V or 5V.

Conclusion

The PX3AF1BH010BSAAX pressure sensor is an ideal device for measuring low-pressure changes in a wide range of applications. It combines high accuracy, low power consumption, temperature compensation, and a range of package types. It is suitable for applications where accuracy, reliability, and low power consumption are important factors.
