Miniature Pressure Transducer


Type/Configuration: absolute, differential.
Output: digital I2C (<15 bit) or SPI.
Package: SMD

Pressure transducer HPSD8000 is a pressure and temperature sensing device specially developed for ultra-low-pressure ranges and demanding space constrictions. High performance and accuracy enable use of this transducer in many applications including differential pressure measurements. Standard 2nd order temperature and pressure compensation provides 0,5% FS total error over 0°C to 70°C temperature range. Single power supply (2.7V – 5,5V), customized compensated pressure and temperature ranges, standard digital I2C, SPI, one wire interfaces or analog voltage output provides OEM users maximum freedom for any type of application with dry air or non-corrosive gases or liquids.

Family HPSD 8000 provides easy integration using small SMD package with footprint pads on short edges leaving enough room for easier routing for the end application. SMD housing is reflow mountable with fast stabilization after soldering process. Pressure ports with their flexibility in different options can accept standard pneumatic tubes or can be customized for integration into end customer housings with straight pressure ports. Different pressure ranges are available for this group starting from 1 mbar up to 10 bar.

Adjustable output resolution (up to 15bits) ADC and DAC included Internal microcontroller.
