Pressure sensors, also known as pressure transducers or pressure transmitters, are devices that measure pressure and convert the mechanical force caused by fluid pressure into a measurable electrical signal. The HSCMANV015PGAA5 is a model of pressure sensor. This article explains its application field and working principle.

Application Field

The HSCMANV015PGAA5 pressure sensor is designed for measuring static and dynamic pressure in liquid, gas or vapour applications. It is commonly used in industrial and commercial fields, such as pressure measurement in process control, fuel cell power plants, hydraulic systems, combustion engines and fluid power applications. The sensor is suitable for a wide variety of measuring pressure range from 0.4 mbar to 16 bar.

Working Principle

The HSCMANV015PGAA5 pressure sensor works on the principle of piezoresistive technology. This technology implies the measurement of variation in electrical resistance caused by the application of pressure to the sensor. It is composed of a piezoresistive element and a pressure-proof tank. Piezoresistive elements are composed of thin layers of piezoresistive material deposited onto the surface of a semiconductor substrate or a diaphragm. When pressure is applied to the piezoresistive element, an electrical signal proportional to the applied pressure is generated.

The signal is amplified and compensated by an ASIC (application-specific integrated circuit). This ASIC ensures a linear output voltage over the complete operating range of the sensor. The pressure-proof tank which encapsulates the piezoresistive element is designed to dissipate the pressure to the atmosphere and dampen the fluctuation so as to increase the accuracy of the measurement.

Conclusion

The HSCMANV015PGAA5 pressure sensor is very useful in process control, fuel cell power plants, hydraulic systems, combustion engines and fluid power applications. It works on the principle of piezoresistive technology, which implies the measurement of variation in electrical resistance caused by the application of pressure to the sensor. The pressure-proof tank encapsulating the piezoresistive element is designed to dissipate the pressure to the atmosphere and dampen the fluctuation so as to increase the accuracy of the measurement.
