RF probe apparatus for NMR check weighing system

Radio frequency apparatus configured for use in a magnetic resonance check weighing system in order to determine the mass of non-continuous and discrete samples in a production line where the production line has a longitudinal axis, comprising:

• a radio frequency probe including a first plurality of substantially planar coil elements and a second plurality of substantially planar coil elements;
• a housing including:
• a first side retaining said first plurality of substantially planar coil elements substantially in a first plane, along the longitudinal axis of the production line and
• a second side retaining said second plurality of substantially planar coil elements substantially in a second plane different from said first plane, which is also along the longitudinal axis of the production line;
• said housing having a passageway between said first side retaining said first plurality of substantially planar coil elements and said second side retaining said second plurality of substantially planar coil elements through which the non-continuous and discrete samples may pass;
• and
• wherein said first plurality of substantially planar coil elements are electrically connected to, and in spatial relation with said second plurality of substantially planar coil elements.
