Product Description
Chinese Bus Auto Parts 3818-00004 Air Pressure Sensor & Air Pressure Sensing Alarm
This high-quality air pressure sensor with integrated sensing alarm function, featuring OEM part number 3818-00004, is a core safety component specially developed for Chinese buses, including mainstream coach, city bus, and passenger bus models.
Product Overview
As a key part of the bus's pressure monitoring and safety early warning system, this component integrates dual functions of air pressure detection and abnormal alarm. It monitors the air pressure of the bus's braking system, tire system, or air intake system in real time, issuing timely alarm prompts when pressure is abnormal to effectively avoid safety hazards and ensure safe bus operation.
Technical Features
- Advanced MEMS sensing technology with diffusion silicon pressure sensing chip
- Measurement range: 0~1MPa with comprehensive precision of 0.5%FS
- Converts pressure information to standard electrical signals (4~20mA two-wire or 0~5V three-wire)
- Integrated high-sensitivity air pressure sensing alarm module with membrane pressure difference induction
- Adjustable alarm thresholds for different bus model requirements
- High-quality engineering plastic shell with corrosion-resistant metal sensing element
- IP65 protection level with excellent sealing and anti-vibration performance
- Operating temperature range: -20℃ to 85℃
- Standard Hirschmann connector and M20×1.5 thread interface for plug-and-play installation
Quality Assurance
All sensors are brand new and undergo strict factory testing including pressure accuracy test, alarm sensitivity test, high-low temperature test, vibration test, and sealing test. Each unit meets relevant national standards and OEM quality requirements with excellent long-term stability and zero temperature drift of ≤±0.05%FS℃.
