Direct-output pressure sensor

Main Features:

This series comprises direct‑wire pressure sensors specially designed for common automotive‑electronics applications. Featuring a stainless‑steel housing and a standard threaded mounting configuration, they are paired with an integrated waterproof wiring harness (optionally equipped with a snap‑on quick‑connect connector). Equipped with a high‑precision piezoresistive pressure sensing element and temperature‑compensation circuitry, these sensors can be directly installed in automotive engines, fuel lines, and brake systems to deliver precise measurements of oil pressure, fuel pressure, and brake pressure. They are widely compatible with the powertrain, fuel system, and safety‑control requirements of both passenger and commercial vehicles.

Core Features

Integrated direct‑out cable design for easy installation. : Utilizes a direct‑outlet waterproof wiring harness, eliminating the need for additional connectors and ensuring easy installation and maintenance. An optional quick‑connect version with locking tabs is available, accommodating the electrical interface requirements of various vehicle models and reducing on‑site installation complexity.
Automotive-grade 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 safety systems.
Stainless steel design for resistance to media corrosion : The stainless steel probe exhibits excellent resistance to corrosion by oils, fuels, brake fluids, 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 vibration resistance It features a sealed structure and a waterproof wiring harness, offering a high level of protection that effectively prevents the ingress of moisture and oil contamination. It is resistant to severe vehicle vibrations and thermal shocks, ensuring stable long-term operation with no drift, and its service life meets automotive electronics industry standards.
