センサ。[Scope of Claim for Utility Model Registration] (1) A container that houses a rotating body in a thrust sensor that detects movement of a rotating shaft made of iron before the thrust bearing that holds the rotating shaft of rotating equipment becomes excessively worn. A relatively thick non-magnetic metal can facing the end face of the rotating shaft with a gap is fitted into the bearing part, and a detection part that detects the movement state of the rotating shaft without contact is fitted inside this can. , this detection section is formed into a twin-coil structure by a sensor coil that operates at a relatively low frequency and a temperature compensation coil provided near the sensor coil, and a sensor coil that is located close to the detection section inside the can. A canned type thrust sensor characterized by having an amplifying section fitted therein. (2) The can-type thrust sensor according to claim 1, further comprising a detection distance adjustment spacer provided between the rotation axis opposing portion of the can and the detection portion. (3) Claim 1 characterized in that a cylindrical can with an outer end opening is attached to the end face of the bearing part of the container, and a detection part and an amplification part are fitted into the can from the outer end opening of the can. Cand type thrust sensor described.
