Pressure sensors and transducers are known for its features of being able to measure and convert ambient pressure into an analog or digital signal. The PPT2-0020DKK2VE is one of the most popular pressure sensing components in the industry. In this article, we will explain the application field and working principle of the PPT2-0020DKK2VE.

Application Field

The PPT2-0020DKK2VE pressure sensor is widely used in industrial pressure measurement systems and control systems. It can measure a wide range of pressures, from low-range to hi-range, which makes it ideal for applications like process control, fluid pressure management, gas pressure measurement, and hydraulic pressure monitoring. Furthermore, the PPT2-0020DKK2VE is also a reliable component for automobile axle pressure measurement, medical equipment pressure measurement, aerospace pressure measurement, and barometric pressure measurement.

Working Principle

The PPT2-0020DKK2VE utilizes the “piezoresistive” effect, or the activity of semiconductors when a certain applied pressure changes their resistance. This pressure sensor is composed of a sensing diaphragm, a base plate, and a semiconductor material (chip). The diaphragm can be of metal or another material with good mechanical properties, depending on the type of application. The chip is composed mostly of a type of silicon crystal, and when pressure is applied, it transmits that pressure to the crystal.

The crystal then transforms the pressure into an electrical signal, and this signal is then sent to the output terminal through a Wheatstone bridge circuit. The Wheatstone bridge circuit also helps to adjust the output voltage according to the resistance change. The output of the PPT2-0020DKK2VE is a linear 0-5V analog voltage signal, which is then used by the system for the pressure readings. This signal can also be converted to a digital signal by an analog-to-digital converter.

Conclusion

The PPT2-0020DKK2VE is a powerful pressure sensor and transducer that measure and convert ambient pressure into analog or digital signals. It can be used in a variety of industrial and automotive pressure monitoring applications, and its working principle relies on the piezoresistive effect. With its ability to measure a wide range of pressures, the PPT2-0020DKK2VE is able to accurately measure and monitor pressure both accurately and precisely.
