MNM IDS671-100K 100,000 lb Low-Profile Compression Load Cell Guide
The IDS671-100K 100,000 lb low-profile compression load cell sold by MNM Scales is a pancake-style disk sensor for very high compression-force measurement where vertical space is limited and a compact force path is preferred.
Verified IDS671-100K listing details
SKU/model: IDS-671-100k.
Rated capacity stated in the description: 100,000 lb.
Sensor format: pancake / low-profile disk compression load cell.
MNM states the 100,000 lb load cell is supplied with a certificate.
The product page is live with Add to cart. The web title contains a typographical extra zero (“100,0000 LB”), while the description clearly states 100,000 lb and the SKU is IDS-671-100k.
Important specifications to confirm before engineering a system
MNM's public page does not list exact rated output in mV/V, bridge resistance, excitation voltage, overload rating, dimensions, thread or loading-button geometry, cable length or wire color code for the IDS671-100K. Those values are essential for OEM integration or replacement work, so confirm them from the supplied certificate, physical sensor label or directly with MNM rather than borrowing values from another 100,000 lb pancake cell.
How a 100,000 lb low-profile compression sensor works
A strain-gauge compression load cell deforms slightly under axial force. Bonded strain gauges change resistance, creating a small bridge signal that an indicator, transmitter or data-acquisition amplifier converts into displayed force after calibration. The useful accuracy of the finished system depends on the sensor plus fixture alignment, reference force, excitation stability, amplification, wiring and environmental conditions.
Mechanical installation for high-force compression
At 100,000 lb, fixture design is as important as sensor selection. Use rigid, flat reaction surfaces designed for the load. Keep force centered, avoid edge loading and provide a loading interface that distributes force into the intended sensing area. The surrounding press frame, bearing plate or machine structure must be engineered for the maximum credible load plus appropriate safety margin.
Do not use calibration to hide a mechanical problem. If the force path rocks, bends, contacts the sensor housing or changes as load increases, the displayed number may look stable while still being wrong.
Calibration and verification
Calibrate the complete installed system with a traceable known force. Establish stable zero with permanent tooling in place, preload the fixture to settle contact surfaces, apply a known span force through the normal load path, then verify several increasing and decreasing force points. At this capacity, calibration may require a calibrated test machine, proving ring, reference load cell or another traceable high-force standard rather than loose deadweights.

Troubleshooting high-force measurement problems
Zero shifts after loading: inspect fixture seating, mounting plates, cable strain and overload history.
Reading differs when the same force is applied twice: inspect contact surfaces, side load, machine friction and frame deflection.
No or very small signal: verify bridge excitation, wiring continuity, amplifier gain and the exact sensor certificate before replacing parts.
Good low-force agreement but growing high-force error: check structural contact, reference-machine accuracy and whether the reaction structure is deforming into an unintended load path.
Frequently asked questions
Is the IDS671-100K rated for 100,000 or 1,000,000 lb?
The MNM description says 100,000 lb and the SKU is IDS-671-100k. The title's “100,0000” wording is treated as a typographical error, not a one-million-pound rating.
Can I connect this directly to a standard PLC input?
A strain-gauge load cell typically needs bridge excitation and signal conditioning before a PLC's 4–20 mA, 0–10 V or digital input. Confirm the exact electrical specification first.
Does the certificate mean the finished machine is calibrated?
No. The supplied load-cell certificate describes the sensor; the installed force-measurement system still needs calibration and verification in its actual fixture.
Where to buy
