CHAPTER 4 PARTS LISTS
GLOSSARY OF TERMS
Agate Bearing: The V shaped Bearing that supports the Knife Edge.
Balance Cup: The Plastic Cup that attaches to the Beam with a bolt and
receives the Balance Plate, Cross or Fork.
Bearing Cover: The Stainless Steel cover that holds the Friction Plate in
place. It must be pried off to check Knife Edges and must
be replaced with new product when removed.
Compensator Assembly: Zero Adjust Knob.
Damper Vane: The Aluminum metal part that is attached to the Beam
and moves between the Magnets to slow the Beam
movement.
How does it work? The Aluminum Vane is nonferrous
and is not attracted to the Permanent Magnet, it is
however an electrical conductor. When it moves through
a magnetic field, it sets up a magnetic field opposing the
magnetic field of the Permanent Magnets. This slows
the Beam movement. The faster the Beam moves, the
stronger the magnetic field. The speed of the Vane is
proportional to the strength of the magnetic field pro-
duced.
Fork: The support mechanism that holds the Scoop.
Cross: The support mechanism that holds the Balance Pan.
Friction Plate: This is the black hardened metal piece that keeps the
Knife Edge in place.
Pan: The removable part of the balance upon which the
sample is placed (raised edge).
Plate: The non-removable part of the balance upon which the
sample is placed (flat).
Poise: The Mass or weight that moves along the Beam.
NOTE: On a two Pan Equal Arm Balance, the sample
is always placed on the left Pan or plate.
