Pressure sensors, transducers, and MPXAZ6115AP all play a role in interpreting information about pressure into a signal that can be more easily read, measured and used. This article will provide an overview of the MPXAZ6115AP application field and working principles, the two components of pressure sensing technology that are commonly used, and how they are typically implemented.

Overview of MPXAZ6115AP Applicable Fields and Working Principle

The MPXAZ6115AP is a pressure sensor transducer module, which uses piezoresistive technology to measure differences in pressure. This pressure transducer designed by Panasonic is a potentiometric pressure sensor, which contains a Wheatstone bridge in the sensing element. This bridge works even for high temperatures thanks to the IC temperature compensation system with dual axes. Therefore, this transducer is suitable for temperature measurement applications. This pressure transducer is used for measuring a wide range of pressure levels. It can measure from 0.5 to 10 bar, and has a resolution of 0.36mV/V/bar.

The working principle of the MPXAZ6115AP is to measure the changes in ‘strain’ due to changes in ‘pressure’. This pressure sensor transducer module is designed to convert the physical pressure variation into a corresponding electrical signal. The Wheatstone bridge contains four strain gauges, which are configured to measure changes in strain due to pressure. When the physical pressure on the surface of the transducer increases, the strain gauge array experiences an increase in resistance. The four strain gauges are connected in a Wheatstone bridge, forming a balanced bridge. If the bridge is perfectly balanced, the output voltage will be zero. However, if the surface is uneven or deformed due to changes in pressure, the resistance of the strain gauges changes, unbalancing the bridge and creating an output voltage. The output voltage is directly proportional to the pressure, allowing the electrical signal to be interpreted and used.

Typical Application of Pressure Sensors and Transducers

Pressure sensors and transducers are commonly used in a variety of applications, including industrial, automotive, heating and cooling, medical, and aerospace. For industrial applications, pressure sensors and transducers are used to monitor machinery performance, control quality, diagnose problems, and ensure safety. Automotive applications include monitoring engine performance, controlling pollution, and controlling and monitoring airbag deployment. Pressure sensors and transducers have also been used in medical and aerospace applications such as systems for oxygen delivery, blood pressure, altitude, and flight control systems.

Typical Implementations of Pressure Sensors and Transducers

Pressure sensors and transducers are typically implemented by connecting the transducer to an amplifier and power supply. The amplifier is used to condition the electrical signal from the transducer and translate it into a useful form for further processing. Additionally, the amplifier also provides current to power the transducer. A power supply is used to provide operating power to the amplifier.

In addition to the amplifier and power supply, additional components may be required to implement a pressure sensing system, depending on the application. This may include analog-to-digital converters (ADCs) for digital reading, display equipment for displaying measurements, and controlling equipment such as valves and actuators for implementing control systems.

Conclusion

The MPXAZ6115AP is a potentiometric pressure sensor that is used for measuring a variety of pressures levels. It contains a Wheatstone bridge in the sensing element, which changes in resistance due to changes in pressure. Pressure sensors and transducers are typically implemented by connecting them to an amplifier and power supply, which conditions the electrical signal and translates it into a useful form for further processing. Additional components may also be necessary depending on the application.
