SDP1000/SDP2000 micro differential pressure sensors are used in HVAC and medical equipment OEMs, with features of no drift, no lag, high precision, high repeatability, complete calibration and temperature compensation, linear or square characteristic output, insensitive to installation direction, and can be directly installed on PCB boards.
The SDP1000 and SDP2000 are CMOSens®‑based differential pressure sensors designed for HVAC and medical device OEMs. They offer high accuracy, low drift, and two output options (linear or square‑root) that can be mounted directly on a PCB.
The document provides detailed sensor specifications, electrical characteristics, mechanical dimensions, recommended wiring, hose guidelines, ordering codes, and safety warnings. It also includes application examples such as VAV systems, fan control, and CPAP equipment. This manual is written in Chinese.
