For help confirming the LPD-CT-100K for a press, test fixture, structural reaction measurement or replacement project, call MNM Scales at (832) 290-3120 or email mnmscales@yahoo.com.

The MNM LPD-CT-100K 100,000 lb low-profile compression load cell is a high-capacity disk-style sensor intended to measure compressive force where vertical space is limited and a platform-style scale is not required. MNM’s exact listing identifies the sensor as LPD-100K / LPD-CT-100K, rates it for 100,000 lb, and states that the load cell is supplied with a certificate. It is a bare force transducer—not a complete force-testing machine—so an indicator or signal conditioner, a mechanically sound fixture and a known-force calibration process are still required.

What Is Verified on the MNM Listing?

The product page verifies a 100,000 lb capacity, low-profile disk compression geometry and a supplied load-cell certificate. It does not publish the sensor’s mV/V sensitivity, bridge resistance, excitation limits, dimensions, connector details, center-thread dimensions or overload ratings. Those missing values matter for OEM integration and replacement work, so obtain the exact data for the cell you are buying before designing electronics or machining a fixture around assumed dimensions.

Why Low-Profile Geometry Matters at 100,000 lb

Large-force fixtures often have very little room between a hydraulic ram, platen, bearing stack or structural reaction point. A low-profile disk can fit into these shorter load paths while keeping the sensing element close to the force interface. The tradeoff is that load introduction becomes critical: the force should be centered, the mating surfaces should be flat and sufficiently stiff, and bending or edge loading should be minimized.

What Else Is Needed to Use the Load Cell?

A complete measurement chain normally includes the load cell, compatible excitation/signal-conditioning electronics, a force or weight indicator, properly shielded wiring, a fixture or machine that transfers force through the sensor, and a calibration method. If the connected indicator supports strain-gauge bridges, the exact cell sensitivity and wiring must be entered or established through a known-load calibration. The display resolution should be chosen based on the actual test tolerance, not simply on the maximum capacity.

Installation Principles

Mount the sensor between clean, flat, rigid surfaces. Avoid welding, drilling or grinding near an installed load cell. Keep hydraulic hoses, frames and reaction members from introducing side force into the sensor. Use mechanical stops or machine controls to prevent accidental overload. At 100,000 lb, even a small alignment error can create a large bending moment, and stored energy in the fixture can be substantial.

Where the LPD-CT-100K Fits

Potential uses include hydraulic-press force measurement, bearing and bushing compression studies, structural reaction-force fixtures, heavy machinery assembly tests, compression proof tests and other controlled test stands. The sensor can also be considered in custom weighing/OEM systems when its exact mechanical and electrical specifications are verified for the design. Read the dedicated hydraulic press and structural-force article for application-specific setup ideas.

Calibration and Verification

Because this is a bare sensor, there is no universal “LPD-CT-100K calibration menu.” Calibration is performed through the connected indicator or data-acquisition system. The correct process is to establish a no-force zero in the finished fixture, apply one or more traceable known forces, set span according to the electronics manual and then verify at several independent force points. For high-capacity systems, qualified calibration equipment or a calibrated reference force standard is usually more practical than stacking dead weights.

Frequently Asked Questions

Is the LPD-CT-100K a complete scale?

No. The MNM listing is for the 100,000 lb low-profile load cell itself. An indicator, wiring, fixture and calibration are required.

Can I connect it to any scale indicator?

Only after confirming the indicator supports the cell’s exact bridge sensitivity, excitation requirement and wiring. Those electrical values are not published on the product page, so verify them before connecting replacement electronics.

Can it measure tension?

The exact MNM listing describes this model as a compression load cell. Do not assume tension capability without explicit model documentation and the correct mechanical interfaces.
