Crankcase Pressure Sensor – High‑Precision Engine Pressure Sensor for Blow‑By Monitoring, Emission Control & Engine Health Management
Product Description
Crankcase pressure sensors are high‑accuracy sensing devices designed to measure the dynamic pressure inside an engine’s crankcase and ventilation system.
Our sensors provide real‑time pressure data to the engine control unit (ECU), enabling advanced monitoring of blow‑by gas flow, oil mist control, and emission management. Engineered for long‑term stability and resistance to oil, fuel vapors, and vibration, they help optimize engine efficiency, protect seals and gaskets, and support compliance with modern emission regulations.
Advantages of Crankcase Pressure Sensor
High sensitivity and accuracy for precise crankcase and ventilation pressure monitoring
Excellent oil, gas, and temperature resistance for harsh under‑hood environments
Long‑term stability under pulsating pressure and high vibration conditions
Fast response for real‑time blow‑by and leak detection
Integrated temperature compensation ensuring stable output
Compact, sealed design compatible with common automotive connectors
Analog or digital output options for direct ECU integration
RoHS, REACH, and AEC‑Q100 compliant for global automotive OEM requirements
