M0443/0707

GENERAL

The OMEGA®LCGD Series bonded foil strain gage load cells are
compression only units that are highly cost effective. To ensure excellent
long term stability and reliability in severe environments, the LCGD
Series utilizes high quality strain gages, precision gaging techniques and
all stainless steel construction. These units have a machined load button
as an integral part of the basic load cell. The LCGD Load Cell is designed
to operate by mounting on a flat surface. The LCGD must rest on a flat
surface at least the diameter D1dimension for proper operation.

The part number indicates the load cell type (LCGD) and load range (eg.,
500 for 500 lb). Models are available with load ranges of 100, 250, 500,
1000, 2000, 5000, 10,000 and 50,000 lb. LCGD series load cells are
compatible with the DP41-S and DP25B-S digital panel meters. These and
other compatible instruments can be found in Section D of the OMEGA
Pressure, Strain and Force Handbook™.
