Abstract
A transducer assembly (300) for a vibrating meter having meter electronics (20) is provided. The transducer assembly (300) comprises a keeper portion (401) comprising a keeper plate (402). A magnet portion (301) comprises a coil bobbin (305) and a coil (309) wound around the coil bobbin (305). A magnet (313) is coupled to the coil bobbin (305). The keeper plate (402) is prevented from contacting the coil bobbin (305).
Claims13
A transducer assembly (300) for a vibrating meter having meter electronics (20), comprising:
- a keeper portion (401) comprising a keeper plate (402);
- a magnet portion (301) comprising:
- a coil bobbin (305);
- a coil (309) wound around the coil bobbin (305);
- a magnet (313) coupled to the coil bobbin (305) with a separate pole piece (311);
- and
- a flux ring (307) disposed between the coil bobbin (305) and the keeper plate (402), wherein the flux (307) ring prevents the keeper plate (402) from contacting the coil bobbin (305), the magnet (313), and the pole piece (311).
A method for forming a vibrating meter including a sensor assembly with one or more flow conduits, comprising steps of:
- forming a keeper portion comprising a keeper plate;
- coupling the keeper portion to a first component of the vibrating meter;
- forming a magnet portion comprising a coil bobbin;
- coupling the magnet portion to a second component of the vibrating meter;
- winding a coil around the coil bobbin;
- coupling a magnet to the coil bobbin with a separate pole piece;
- placing the keeper plate proximate the magnet;
- disposing a flux ring between the coil bobbin and the keeper plate;
- preventing the keeper plate from contacting the coil bobbin, the magnet, and the pole piece with the flux ring;
- and
- electrically coupling the coil to a meter electronics.
