MAGNETIC LOAD SENSOR UNIT

摘要

A magnetic load sensor unit is provided which can detect a load with a minute movement of its part, and which is durable and less likely to be influenced by temperature. The sensor unit includes a flange member (1) deflectable when an axial load is applied, a support member (2) supporting the flange member (1), a magnetic target (3) which generates a magnetic field, and a magnetic sensor (4) for detecting the magnetic field generated by the magnetic target (3). The magnetic target (3) and the magnetic sensor (4) are fixed to the flange member (1) and the support member (2), respectively, such that when the flange member (1) is deflected, the magnetic target (3) and the magnetic sensor (4) move relative to each other, whereby magnitude of the load can be detected based on the magnetic field detected by the magnetic sensor (4).

1. A magnetic load sensor unit comprising:
a flange member configured to be deflected when an axial load is applied; a support member supporting the flange member; at least one magnetic target which generates a magnetic field; and at least one magnetic sensor for detecting a magnetic field generated by the magnetic target; wherein one and the other of the magnetic target and the magnetic sensor are fixed to the flange member and the support member, respectively, such that when the flange member is deflected, the magnetic target and the magnetic sensor move relative to each other, whereby a magnitude of the load applied is detectable based on a magnetic field as detected by the magnetic sensor.
