Omega Products LCWD-10K Installation Manual
NOTE:
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:

HOW LOAD CELLS WORK
Load cells have an output or sensitivity in mV/V. What this sensitivity/output represents is as follows:
Change in millivolt output
from zero load to the full
scale capacity of the load cell
(21.3 mV in this example)
No load cell has exactly zero millivolts at no load. Most cells have a small millivolt DC offset of a few millivolts
which is normal. To scale a system the end user just scales his recorder/meter for a full scale change of (21.3 mV
per example), and connects the load cell in a no load situation and rezeros the pens/display for a correct zero
reading.
