Apparatus to attach sensors on equipment with rotating shafts

Abstract

An apparatus for attaching sensors to rotating shafts on equipment includes a cup magnet and a housing for receiving the cup magnet. A target rotor is displaced within the housing which rotates when attached to a rotating shaft for the purpose of sensing the shaft rotation. Alternately, the cup magnet may be permanently attached to a rotating couple rather than a non-rotating housing. A preferred embodiment may have a dust cover.

1. An apparatus for attaching sensors to rotating shafts on equipment comprising:
 a rotatable cup magnet magnetically attachable to an end of the  a rotating shaft;  
 a non-rotating housing for receiving  cooperating with said cup magnet and capable of  receiving a sensor;  
 a target rotor displaced  disposed within said cup magnet  housing and rotatable with the cup magnet as the cup magnet is rotated  
 whereby the sensor senses the target rotor rotation as the cup magnet rotates in conjunction with the rotating shaft.  
 
     
     
       2. The apparatus of  claim 1  further comprising  wherein the sensor is a switch for sensing movement of said target rotor. 
     
     
       3. The apparatus of  claim 1  further comprising a dust cover about said cup magnet. 
     
     
       4. An apparatus for attaching sensors to rotating shafts on equipment comprising:
 a rotatable cup magnet magnetically attachable to an end of the rotating shaft;  
 a coupler for fixably receiving said cup magnet and capable of receiving a sensor;  
 a fixation point for attachment of said coupler  a sensor to said shaft  coupler  
 whereby the sensor senses the rotation of the cup magnet in conjunction with the rotation of the shaft.  
 
     
     
       5. The apparatus of  claim 4  wherein a setscrew is located at said fixation point. 
     
     
       6. The apparatus of  claim 4  where said cup magnet is attached to said coupler with glue. 
     
     
       7. Apparatus for sensing a rotating shaft on equipment comprising:
   a sensor;        a rotatable cup magnet magnetically attachable to an end of the rotating shaft;        a non - rotating housing for cooperating with said cup magnet and capable of receiving said sensor;        a target rotor disposed within said housing and rotatable with said cup magnet as said cup magnet is rotated        whereby said sensor senses the target rotor rotation as the cup magnet rotates in conjunction with the rotating shaft.      
     
     
       8. Apparatus for sensing rotating shafts on equipment comprising:
   a sensor device;        a rotatable cup magnet magnetically attachable to an end of the rotating shaft;        a coupler for fixably receiving said cup magnet and capable of receiving said sensor device;        a fixation point for attachment of said sensor device to said coupler        whereby said sensor device senses the rotation of said cup magnet in conjunction with the rotation of the shaft.
