On‑Board Pressure Sensor

Product Overview

On‑board pressure sensor is a key automotive physical signal detection component, used for real‑time monitoring of liquid pressure and gas pressure inside vehicle pipelines and functional assemblies. The product converts tiny pressure changes into standard linear electrical signals, providing accurate and continuous data basis for vehicle ECU closed‑loop control and fault judgment. With automotive sealed packaging and professional environmental adaptation design, it meets the high‑precision and high‑stability detection demands of core vehicle safety systems.

Core Performance Parameters

• Detection accuracy: high linear precision, ultra‑low full‑scale error and stable signal output

• Environmental resistance: IP67 dustproof and waterproof grade, fully adapted to chassis and engine cabin installation environment

• Structural performance: anti‑vibration and anti‑impact packaging design, resisting long‑term road vibration impact

• Temperature stability: extremely low temperature drift coefficient, ensuring consistent precision under rapid temperature change

• Service life: long‑term cycle working design, matching vehicle million‑kilometer operating life standard

Adaptable Working Conditions

The sensor can stably work in high temperature, humidity, dust and complex vibration environments inside automobile chassis, brake pipelines, cooling systems and tire cavities. It effectively resists pipeline fluid impact, environmental temperature alternating change and vehicle running electromagnetic interference, realizing all‑weather reliable detection.

Product Advantages

With high precision and high repeatability, the sensor effectively avoids data drift and detection failure. Optimized automotive anti‑vibration packaging structure enhances structural stability during vehicle driving. Excellent temperature drift suppression technology ensures consistent detection accuracy in high and low temperature environments. Standard automotive electrical interface facilitates rapid assembly and batch production matching.

Application Scenarios

Mainly used for automobile brake oil pressure monitoring, engine cooling system water pressure detection, turbocharging pressure sampling, tire pressure real‑time monitoring and new energy vehicle thermal management system pipeline pressure detection, providing core data support for vehicle safety and energy‑saving control.

Installation & Maintenance Guidelines

Install at fixed and stable positions to avoid long‑term eccentric vibration and mechanical impact. Ensure sealed installation to prevent dust and water vapor from invading the sensing core. Regularly calibrate detection accuracy during vehicle maintenance to avoid performance attenuation caused by long‑term operation. Strictly follow automotive wiring specifications to prevent signal interference and ensure accurate data transmission.
