SDP1108 is a micro differential pressure sensor with fast response, high sensitivity, no drift, no lag, full calibration and temperature compensation, which is suitable for medical ventilators (ICU ventilators and home ventilators) and other occasions.
The SDP1108 micro‑differential pressure sensor provides rapid response and high sensitivity below 10 Pa, making it suitable for ICU and home ventilators, CPAP devices, anesthesia machines and other medical airflow applications. It is built with Sensirion's CMOSens® technology, integrating the sensing element, amplification and A/D conversion on a single silicon chip, and includes full temperature compensation and zero‑drift correction.
The sensor operates from a 5 V supply and delivers an analog voltage output of 0.25 V to 4 V. It offers multiple selectable pressure ranges (e.g., –5 to 125 Pa) and a typical accuracy of 0.05 Pa. The robust PPS housing meets RoHS standards, has an IP00 rating, and can withstand over‑pressure up to 1 bar (instantaneous up to 2 bar). This manual is written in Chinese.
