Annular Embedded Pressure Sensor

Main Features:

This series comprises annular, embedded pressure sensors specially designed for the unique installation requirements of the low‑altitude economy. Featuring an annular hollow structure and a high‑strength engineering‑plastic housing, they incorporate a high‑precision piezoresistive pressure sensing element and an integrated signal‑conditioning circuit. These sensors can be directly mounted on the rotating shafts, fluid lines, or within compact equipment compartments of low‑altitude vehicles, enabling precise measurement of local ambient pressure, fluid pressure, or pressure at specific locations. They are widely suited to meet the integrated monitoring needs of drones, low‑altitude operation platforms, and specialized vehicles.

Core Features

Annular hollow structure, suitable for special installation scenarios. : Featuring a ring‑shaped hollow design, it can be directly slipped over a rotating shaft or pipeline, or embedded in tight spaces, eliminating the need for additional installation space and meeting the specialized structural integration requirements of low‑profile platforms.
High integration and lightweight design : The integrated engineering-plastic housing is lightweight and impact-resistant, with a low weight and compact size that does not impose additional load on the vehicle, facilitating rapid integration into complex structures.
High precision and stable output : Featuring a built-in high-precision piezoresistive pressure sensing element and a temperature-compensation circuit, it delivers stable, high‑accuracy pressure measurement across a wide temperature range of –40°C to +125°C, with reliable output signals that provide precise data support for vehicle control systems.
Environmental resistance and anti-interference : The sealed enclosure features a high protection rating, effectively preventing the ingress of moisture and dust, and can withstand vibration, impact, and electromagnetic interference during low-altitude operations, ensuring stable long-term performance with no drift.
