Durable Ceramic Pressure Sensor for Automotive Industry
High-performance 0-10bar capacitance pressure sensor available in 18mm, 20mm, and 21mm configurations for vehicle intake, exhaust, and thermal management systems.
Product Overview
Constructed with 96% ceramic material, this pressure sensor offers exceptional corrosion resistance, impact durability, high elasticity, and thermal stability. Operating temperature range spans from -40℃ to 135℃, making it ideal for demanding automotive applications.
The ceramic capacitance pressure sensor operates with direct pressure application on the ceramic diaphragm. Pressure changes create proportional capacitance variations between the base electrode and diaphragm electrode. Overload protection is built-in, with the diaphragm contacting the base without damage, ensuring performance recovery after pressure normalization.
Key Features
- Superior corrosion and impact resistance
- High stability and temperature tolerance
- Minimal hysteresis and rapid response
- Extended service life exceeding 5 million pressure cycles
- Compatible with various media including air, oil, brake fluid, gasoline, diesel, and refrigerants
