Core Features

Brass housing design, compatible with refrigerant media. It features a brass housing that comes into direct contact with the refrigerant, offering excellent resistance to refrigerant‑induced corrosion and superior sealing performance. With excellent compatibility with air‑conditioning refrigerants, it can withstand prolonged immersion in these media, ensuring long‑term operational stability.
Automotive-grade high precision and wide-temperature-range stability : 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, providing reliable data support for the vehicle‑mounted air‑conditioning ECU and ensuring the system’s stable operation and energy‑efficient control.
Automotive standard quick-connect connector, easy to install. Equipped with automotive‑standard quick‑connect electrical connectors, it can be directly mated to the vehicle’s air‑conditioning system wiring harness, eliminating the need for additional adapters. This ensures easy installation and maintenance, while supporting the air‑conditioning system specifications of mainstream vehicle models.
High protection and vibration resistance It features a sealed structural design with a high protection rating, effectively preventing the ingress of moisture and oil contamination. It is resistant to severe vehicle‑mounted vibrations and thermal shocks, ensuring stable long‑term operation without drift, and its service life meets automotive electronics industry standards.
