Core Features

High-precision differential pressure measurement with excellent stability. It employs a high-precision differential pressure sensing element, featuring low temperature drift and excellent long-term stability, enabling accurate detection of minute pressure differentials and providing reliable differential pressure data for smart home appliances.
Dual‑nozzle design for easy pipeline connection. : The integrated dual-pressure air nozzle can be directly connected to the pipeline, eliminating the need for additional adapters and simplifying equipment flow‑path design. It is suitable for differential pressure monitoring in gas‑line applications such as fresh‑air systems and air purifiers.
Low-power, surface-mount design, compatible with smart home appliances. It employs an SOP surface-mount package, features a compact footprint, and can be directly mounted using reflow soldering. With low operating current, it aligns with the trends toward miniaturization and low power consumption in smart home appliances and small devices.
Standard SMT package, easy to manufacture. It adopts industry-standard chip‑scale packaging and pad definitions, enabling direct integration with SMT manufacturing processes without additional steps, thereby reducing equipment integration complexity and production costs, and supporting large‑scale mass production.
