Debugging guide: differential pressure sensor WF200DP in ventilator products
This article introduces the application and commissioning guide of WF200DP differential pressure sensor in ventilator products.With ±5000Pa range and ±0.1%FS accuracy, WF200DP supports I2C and digital output, and has been widely used in respiratory flow measurement. The article focuses on the working principle of the sensor, common problems and solutions during commissioning, including I2C communication, low-pass filter settings, temperature compensation and secondary calibration methods, to help engineers optimize design and improve accuracy.
