Flange-Mounted Miniature Pressure Sensor

Main Features:

This series comprises miniature pressure sensors with flange mounting, specifically designed for small unmanned aerial vehicles in the low‑altitude economy. Featuring a flanged mounting base and an integrated sealed housing, they incorporate a high‑precision piezoresistive pressure sensing element and a temperature‑compensation circuit. With high integration, lightweight construction, and exceptional stability, these sensors can be directly embedded into the payload compartments of small drones, micro‑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

Flange mounting, integrated for convenience. It features a flange‑type mounting base with standard mounting holes, allowing direct screw fixation for secure installation that resists loosening. Designed to withstand prolonged operation under high‑vibration conditions with low‑payload platforms, it facilitates rapid integration into equipment enclosures.
Miniaturization and Lightweight Design : The overall structure is compact and lightweight, designed to meet the space and payload constraints of small low-altitude platforms, without imposing additional burden on the platform and enabling seamless integration into confined spaces.
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 support for altitude estimation and attitude control in small unmanned vehicles.
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.

Typical application scenarios

In-cabin barometric pressure monitoring and altitude‑navigation assistance for small unmanned aerial vehicles and multirotor aircraft
Cabin pressure acquisition for micro air vehicles and eVTOL small-scale aircraft
Environmental pressure and altitude data monitoring for low-altitude operation robots and inspection platforms.
Embedded pressure-sensing module for small meteorological terminals and low-altitude environmental data acquisition devices
