Pressure sensors and transducers play an important role in monitoring and controlling pressure levels in various areas such as industrial and medical applications, as well as in the automotive, defense and aerospace sectors. The MPXV7002GP is a pressure sensor from Freescale Semiconductor that is widely used in these applications. In this article, we\'ll look at the application fields and working principle of the MPXV7002GP.

MPXV7002GP Application Fields

The MPXV7002GP is a pressure sensor that provides an output voltage that is directly proportional to changes in applied pressure. This pressure sensor is used in a variety of applications such as automotive systems, home appliances, medical devices, and industrial applications. It can measure both positive and negative differential pressure, making it ideal for applications that require accurate measurement of pressure changes. It is also suitable for use in harsh environments such as high-temperature and dust-filled atmospheres, making it a great choice for industrial and automotive applications.

In automotive applications, the MPXV7002GP is used for tire pressure monitoring systems (TPMS), airbag deployment, and intake manifold pressure monitoring. It can also be used in medical applications such as respiration rate monitoring, oxygen delivery, and anesthesia ventilation. Other applications include HVAC pressure sensing, vacuum valve monitoring, fluid flow measurement, and pneumatic control systems.

MPXV7002GP Working Principle

The MPXV7002GP pressure sensor consists of a sensing element that is surrounded by a circular diaphragm. A piezoresistor, which is composed of a thin sheet of resistive material, is mounted on top of the diaphragm. As the pressure of the environment increases, the piezoresistor deforms and changes its resistance, which is proportional to the applied pressure. This change in the resistance is measured by the sensor and is translated into a voltage output.

The output of the MPXV7002GP is an analog voltage signal that is proportional to the applied pressure. The output voltage is typically between 0.6 and 4.0 V, with a resolution of 0.2 mV/V. The output voltage can be converted to pressure readings using a suitable circuit or an external data convertor. The MPXV7002GP is designed to operate over an input pressure range of up to 500 mbar and can be used in temperatures of between -40 and 125 °C.
