The MNM IDS-672-3K-CT 3,000 lb center-thread pancake load cell is a low-profile steel force sensor that MNM identifies as model IDS-672-3k center thread and supplies with a load-cell certificate. Its compact disk geometry makes it useful when a conventional S-beam would add too much height to a test stand or compression fixture, while the center-thread interface gives integrators a defined point for an appropriately designed mechanical connection.

Verified Product Details

MNM’s current product page lists the brand as MNM Scales, the model as IDS-672-3k center thread, a 3,000 lb pancake compression-load-cell capacity and a certificate with the load cell. The page does not publish rated output, bridge resistance, excitation, dimensions, thread pitch, overload or environmental sealing. Those values must be confirmed before replacing another model or designing electronics and machining around this sensor.

Pancake vs. S-Type Geometry

An S-type sensor is convenient for inline tension/compression because the force enters through opposite threaded ends, but it can be relatively tall. A pancake/disc sensor puts the strain-gauge structure into a flatter body. That can reduce test-stack height and improve packaging in presses, spring fixtures, actuator stands and OEM machines. The tradeoff is that the surrounding fixture must provide good centering and support because off-axis loading can distort the measurement.

Center Thread: What It Helps With

A central threaded feature can simplify attachment of a rod, adapter or loading component compared with a plain compression-only puck. But thread size, engagement depth and approved force direction are part of the mechanical rating. Obtain the exact dimensional drawing before selecting hardware. Do not assume a bolt that fits visually is suitable for 3,000 lb force or for tension use.

Electronics and Indicator Integration

The sensor needs excitation and a device to convert its bridge signal into force units. Depending on the application, that may be a digital scale indicator, a force display, an amplifier feeding a PLC, or a data-acquisition interface. Confirm the exact cell sensitivity and excitation limits first; the public MNM listing does not state them. If the test involves fast peaks, choose electronics with a sample rate appropriate to the event rather than relying only on display resolution.

Mechanical Installation

Keep the load path centered, use stiff and flat mating surfaces, and prevent the disk from seeing side force or torque. If the fixture can overtravel, provide an independent mechanical stop or machine limit. Cable routing should keep the cable away from sharp edges, moving platens and high-current motor wiring that can add electrical noise.
