Coil airflow sensor reference design for predictive maintenance
The TIDA-01070 TI design provides a reference for monitoring airflow efficiency and temperature through HVAC systems. The design is used in conjunction with solid state relays and piezoelectric vibration sensors to monitor and react accordingly to low airflow and low temperature conditions through the air handler.
The system also includes a calibration algorithm for consistent performance across all system setups.
Features
- Low temperature condenser cutoff.
- One button system calibration.
- Designed to work with air handler 24 VAC transformer.
- 14.08 mA current consumption when running.
- Operating conditions: -40 to +85°C.
