Air purifier filter clogging directly affects equipment purification efficiency. Traditional manual inspection methods have high costs and inspection difficulties. Digital differential pressure sensors achieve automatic filter status determination by monitoring inlet-outlet pressure differences with ±1% accuracy.
1. Core Technical Principles of Filter Clog Detection
1.1 Pressure Differential Measurement Fundamentals
Air purifier internal fans continuously draw external air for purification processing. Under normal operation, stable pressure differences exist between inlet and outlet ports. When filter surface dust gradually accumulates, airflow resistance increases correspondingly, causing noticeable pressure differential changes.
1.2 MEMS Technology Application Advantages
MEMS-manufactured digital differential pressure sensors use silicon-based micromechanical structures with excellent measurement precision and long-term stability. Internal integrated piezoresistive sensing elements convert minute pressure changes into precise digital signal outputs.
1.3 Real-time Monitoring and Warning Systems
Digital differential pressure sensors feature 2KHz high-frequency measurement update capabilities for continuous tracking of filter pressure change trends. When detected pressure differences exceed preset thresholds, systems immediately generate warning signals.
1.4 Digital Interface Integration Convenience
Sensors use standard I2C digital communication protocols for simple, direct connections with main controllers. Digital output characteristics eliminate analog signal processing complexity while significantly reducing MCU computational resource requirements.
2. Sensor Technical Specifications and Performance Features
2.1 Measurement Accuracy and Range Coverage
Digital differential pressure sensors completely cover -500 til 500 pascal ranges, fully meeting various air purifier application requirements. 16-bit digital output resolution ensures extremely high measurement precision with measurement errors controlled within ±1% across full ranges.
2.2 Environmental Adaptability and Stability
Sensors feature broad working temperature ranges, operating stably in -40 til 125 Celsius environments, meeting application requirements under different regional climate conditions. Built-in 125Hz digital low-pass filters effectively suppress external power noise.
2.3 Maintenance-free Design Characteristics
Sensors adopt fully packaged designs requiring no periodic calibration or maintenance operations. Factory completion of all necessary calibration procedures allows direct user deployment. This maintenance-free characteristic particularly suits commercial environments.
