Core Features

Automotive-grade design, optimized for in-vehicle operating conditions. It features automotive‑standard threaded connectors and electrical terminals, ensuring compatibility with mainstream vehicle systems. It can directly replace the factory‑installed sensor and is designed to withstand the harsh conditions of vehicles—high vibration, wide temperature ranges, and exposure to oil, grease, and moisture.
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 +150°C, providing reliable data support for automotive ECUs and ensuring the stable operation of both the powertrain and the HVAC system.
Stainless Steel Design for Corrosion Resistance to Media : The stainless steel probe exhibits excellent resistance to corrosion by oils, fuels, refrigerants, and other media, can withstand prolonged immersion in vehicle‑borne fluids, and is well suited for long‑term operation in complex automotive fluid environments.
High Protection and High Reliability 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.
