Abstract
A transducer assembly 200 for a vibrating meter 5 having meter electronics 20 is provided according to an embodiment. The transducer assembly 200 comprises a coil portion 204A comprising a coil bobbin 220 and a coil 222 wound around the coil bobbin 220. A magnet portion 204B comprises a magnet. The coil portion 204A and the magnet portion 204B are constrained in both the x and y axis of travel, such that the coil portion 204A is prevented from colliding with the magnet portion 204B.
Claims17
A transducer assembly (200) for a vibrating meter (5) having meter electronics (20), comprising:
- a coil portion (204A) comprising a coil bobbin (220) and a coil (222) wound around the coil bobbin (220);
- a magnet portion (204B) comprising a magnet (211);
- wherein the coil portion (204A) and the magnet portion (204B) are constrained in both the x and y axis of travel, such that the coil portion (204A) is prevented from colliding with the magnet portion (204B).
A flowmeter (5) comprising:
- meter electronics (20) a first conduit (103A);
- a second conduit (103B);
- a magnet portion (204B) comprising a magnet (211), wherein the magnet portion (204B) is attached to the first conduit (103A);
- a coil portion (204A) comprising a coil bobbin (220) and a coil (222) wound around the coil bobbin (220), wherein the coil portion (204A) is attached to the second conduit (103B);
- a physical stop attached to each of the first conduit (103A) and second conduit (103B), wherein the physical stops are configured to contact each other to limit conduit (103A, 103B) travel, wherein the coil portion (204A) and a magnet portion (204B) are prevented from colliding with each other.
A method of forming a vibrating meter including a sensor assembly with one or more conduits, comprising steps of:
- affixing a coil portion to a conduit;
- affixing a magnet portion to a different conduit;
- wherein the coil portion and the magnet portion are constrained such that the coil portion is prevented from colliding with the magnet portion.
