SENSOR ASSEMBLY AND SENSOR SYSTEM FOR COMBINED BEARING LOAD SENSING AND BEARING HEALTH MONITORING

摘要

Sensor connects, and the bearing of petite person's bearer ring (11) is attacked for measuring load, at least one described bearing is with cavity (12), for accommodating sensor module. The sensor module include between series mounting opposite side (17,18) cavity (12), series mounting includes piezoelectric board (16) and spring (13) and rigidity k. Optionally, sensor unit further includes that ontology (14) have installation piezoelectric board (16) and spring (13) between quality m, to allow load measurement and health monitoring simultaneously.
