2.2 Open Magnets
When using an open magnet, make sure the rod is positioned at all times within the “active” zone of the
magnet. The transducer cannot operate properly unless the entire stroke of the transducer rod is located
within this zone. The active zone, as shown in Figure 2-7, lies within the inside diameter of the magnet.

2.3 Spring Loading or Tensioning
The transducer rod can be spring loaded or tensioned using a stationary weight. Attach a spring mecha-
nism or weight to the dead zone of the transducer rod with a clamping device which will not deform the
transducer rod. The maximum weight or spring tension is 5 to 7 lbs.
