Cautionary Notes for Safe Product Use.
DESCRIPTION
The OMEGA ® LCWD Series Load Cell is a compact design with a full Wheatstone Bridge. Typical applications
include Clamping Forces, Die Loads, Bolt Stresses, Weighing Systems, and Structural Loads.
The load washer can be used as a washer, sensing compression force, or a compression load cell. When utilized
as a compression load cell, the load buttons supplied should be used. If the height of the buttons provided is too
restrictive, you can use one or none of the buttons. When you are using less than 2 buttons, be sure that the
active ridge (inside) of the washer is seated on a flat surface that transmits the load. Whenever possible, the
buttons provided should be used because they insure correct loading.
When used as a washer load cell, the set of spherical washers should be used as a washer cell, the set of
spherical washers should be used on one side of the load cell and a flat washer (not provided) on the other side of
the washer. When choosing a flat washer, make sure that the inner diameter of the flat washer is less than the
diameter of the inner ring of the load washer to insure that the active ridge is seated on the flat washer.
The following load cell types are available from OMEGA Engineering:
