Omega LCGB-3K Compression Load Cell
The Omega LCGB-3K is a miniature, low-profile stainless steel compression load cell rated for 3,000 lbf (1,361 kg). It produces a 2 mV/V nominal output at 10 Vdc excitation, mounts to a flat surface through the body with #4 cap screws on a 1.25 in (31.8 mm) bolt circle, and uses an integral spherical load button for even force distribution. It ships with 5-point NIST-traceable calibration and 59K ohm shunt data.

Best for
- In-line and through-body compression force measurement in tight, low-clearance assemblies
- Long-term load monitoring in harsh industrial environments where stainless steel construction matters
- Test stands, press and clamp force verification, and machine-mounted weighing up to 3,000 lbf
- Integration with Omega DPiS, DP41-S, and DP25B-S strain meters

Frequently Asked Questions
What is the rated capacity of the Omega LCGB-3K?
The LCGB-3K is rated for 3,000 lbf (1,361 kg) in compression, with a safe overload of 4,500 lbf (150%) and an ultimate overload of 9,000 lbf (300%).
What output and excitation does the LCGB-3K use?
It provides a 2 mV/V nominal output at 10 Vdc excitation across a 350 ohm minimum bridge, compatible with standard strain-gauge meters including Omega DPiS, DP41-S, and DP25B-S.
How is the LCGB-3K mounted?
It mounts through the body to a flat base using #4 socket-head cap screws on a 1.25 in (31.8 mm) bolt circle. An integral spherical load button on top distributes the applied force evenly.
Does the LCGB-3K come calibrated?
Yes. Every unit ships with 5-point NIST-traceable (0/50/100/50/0%), 59K ohm shunt data included.
What is the accuracy of the LCGB-3K?
Linearity is ±0.25% FSO, hysteresis ±0.20% FSO, and repeatability ±0.10% FSO. Compensated temperature range is 60 to 160 F (16 to 71 C).
