Pressure Sensors and Transducers

Pressure sensors are essentially devices that measure the amount of force applied to an object. They can detect the pressure applied to a standard pressure line, as well as measure fluid and gas pressures. Pressure sensors are employed in a wide range of applications such as medical, aerospace, automation, industrial production, automotive, and power plants. Pressure transducers are essentially devices that convert pressure measurements into an electrical signal, which is then used to measure, display, or otherwise process the pressure data.

PPT2-0020DKK5VS Application Field and Working Principle

The PPT2-0020DKK5VS pressure transducer is a miniature, high-resolution digital pressure sensor used to measure absolute pressure in various applications. The device is used in medical, automotive, and industrial applications, for measuring a range of normal atmospheric pressure and vacuum levels. It has a very small size, and is available in a range of different sensitivities and performance ratings. The device is capable of providing a resolution of 0.01 Bar in the range between 0-3 Bar.

The device features a piezoresistive microbridge on a monolithic silicon chip. This device uses two piezoresistors, creating a Wheatstone bridge for measuring pressure. When the pressure is applied, it causes a strain on the device, which is converted into an electrical signal. This signal is then amplified and passed to an analog-to-digital converter. This results in a direct digital output, bypassing the need for any analog circuitry.

The PPT2-0020DKK5VS features a high accuracy of 0.25%, a fast response time of 10 milliseconds, and a temperature coefficient better than ± 0.25% at a single temperature. It is capable of measuring absolute pressure and relative pressure levels. The device is packaged in a miniature size of 4.8 x 8.4 x 1.9 mm and is suitable for applications where space is limited. It is available in a variety of electrical interfaces such as I2C, SPI, and UART. It also features a surface mountable design and is available with an optional over-temperature protection.

The device is hermetically sealed and is fully protected from mechanical stress and environmental conditions such as humidity and contamination. Furthermore, it is designed to meet the applicable standards for EMC and RoHS.

In conclusion, the PPT2-0020DKK5VS pressure transducer is a miniature, high-resolution digital pressure sensor used in various applications for measuring pressure levels. It features a piezoresistive microbridge on a monolithic silicon chip, which is capable of providing a resolution of 0.01 Bar in the range between 0-3 Bar. It is hermetically sealed, and is available with a variety of electrical interfaces and over-temperature protection.
