The MNM Scales 25,000 lb x 1 lb low-profile compression scale is a portable high-force measurement package built around a 25,000 lb pancake/disk-style compression load cell and LP7516 digital indicator. The low-profile sensor geometry is useful where a tall S-beam would not fit or where force is applied vertically through a press platen, bearing fixture, machinery support, structural test fixture or other compression-only load path.
Core Product Specifications
MNM lists the complete system at 25,000 lb capacity with 1 lb indicated resolution. The package includes a low-profile 25k compression load cell, LP7516 indicator, rechargeable battery/power setup and a load-cell certificate. The listing describes a 6-digit indicator with zero, gross/net/tare, accumulation, printing, counting, check weighing and auto-hold functions, selectable lb/kg units and RS-232 output.
Why Use a Low-Profile Compression Load Cell?
Pancake and disk sensors place the force-sensitive element in a compact vertical package. This makes them practical under hydraulic press platens, reaction fixtures, machine supports and component test rigs. The load should be centered over the sensing area and transferred through flat, stiff contact surfaces. Eccentric loading, rocking fixtures, point contact and bending can reduce repeatability even when the indicator and load cell are correctly calibrated.
LP7516 Indicator Functions
Public LP7516 documentation describes general weighing, zero/tare, hold functions, accumulation, optional RS-232, a 6-digit display and rechargeable-battery operation. It also documents a 10-times high-resolution display mode for brief diagnostic viewing and a calibration menu that includes unit, decimal, division, capacity, zero and loading calibration parameters. Use the shipped product configuration as the baseline and record settings before changing service parameters.
Applications
For press-fit, bearing installation and hydraulic press measurement, read the 25,000 lb hydraulic press and bearing test guide. For vehicle components, machine supports and structural compression work, see the truck suspension, machinery and structural test guide.
Setup Checklist
Place the load cell on a rigid surface capable of supporting the full test force. Use a hardened or otherwise suitable load-introduction plate when needed to distribute force properly. Keep the sensor centered under the applied load. Route the cable away from pinch points and moving press components. Power on unloaded, allow the indicator to stabilize, confirm zero and then apply force smoothly. After the test, remove load and verify return to zero.

Frequently Asked Questions
Is this a tension load cell? The MNM listing describes a low-profile compression load cell, so use it for compression loading unless the exact sensor documentation explicitly states otherwise. What does 25,000 lb x 1 lb mean? It is the nominal capacity and display increment of the system. Can the LP7516 be calibrated? Yes; public LP7516 documentation includes C05 zero and C06 loading calibration. Does it have RS-232? The listing and LP7516 documentation include serial-output capability. Is this appropriate for a hydraulic press? It can measure compression force in a properly engineered press fixture within its rating.
