Product Overview

DWSPD is a digital signal output micro-differential pressure sensor developed by Duwei Intelligence. This series utilizes a high-performance ASIC to calibrate and compensate the MEMS sensor element, ensuring product reliability. It converts pressure difference signals ranging from ±500Pa to ±350KPa into I2C digital output signals. The pressure sensor can be integrated onto a standard printed circuit board.

It is widely used in air or neutral gas detection and control, suitable for gas pressure detection in various ventilation and air conditioning systems and equipment, as well as differential pressure monitoring applications in cleanrooms, biological laboratories, and gas pipeline filter resistance.
