The utility model combines two types of force sensors structurally to solve the deficiencies of a single type of sensor in terms of accuracy, sensitivity, stability, etc. during pulse condition collection, and improves the quality of pulse condition data collection to facilitate further pulse condition analysis and diagnosis.
