Column-type high-precision pressure sensor

Main Features:

This series comprises column‑type, high‑precision pressure sensors specifically designed for the low‑altitude economy. Featuring a black anodized aluminum housing and an integrated sealing structure, they incorporate a high‑accuracy piezoresistive pressure sensing element and a temperature‑compensation circuit. With high integration, exceptional stability, and broad temperature‑range compatibility, these sensors can be directly embedded in unmanned aerial vehicles, manned aircraft, and low‑altitude operational platforms, enabling precise measurement of cabin pressure, ambient pressure, and altitude. They are widely suited to meet the navigation‑assistance, attitude‑control, and safety‑monitoring requirements of low‑altitude vehicles.

Core Features

High integration and compact design It adopts an integrated cylindrical structure, with an anodized housing that is lightweight and highly rigid. It can be directly mounted inside the equipment bay of low‑altitude platforms, making it well suited for installation in confined spaces and facilitating rapid integration.
High precision and wide-temperature-range stability : Featuring a built-in high-precision piezoresistive pressure sensor and an intelligent temperature-compensation circuit, it delivers stable, high‑accuracy pressure measurement across a wide temperature range of –40°C to +125°C, providing reliable data for altitude estimation and attitude control in low‑altitude unmanned platforms.
Environmental resistance and high reliability It features a sealed enclosure with a high protection rating, effectively preventing the ingress of moisture and dust, and can withstand vibration, impact, and temperature fluctuations during low-altitude operations, ensuring stable long-term performance with no drift.
Standardized communication and easy integration Supports mainstream digital communication protocols (I2C/SPI/UART), enabling direct interfacing with flight control systems and onboard equipment, thereby reducing integration and development complexity and ensuring compatibility with control and data acquisition systems for various low-altitude platforms.

Typical application scenarios

In‑cabin barometric pressure monitoring and altitude‑navigation assistance for unmanned aerial vehicles and multirotor aircraft
Cabin pressure acquisition for manned low-altitude aircraft and eVTOL electric vertical takeoff and landing vehicles.
