MNM Scales 100 lb Load Cell for Spring, Cable & Small Component Force Testing
The MNM Scales 100 lb load cell for spring, cable and small component force testing is a useful fit when the test needs more detail than a heavy crane-scale system can provide. Its 100 lb range and 0.02 lb displayed increment are well suited to controlled bench fixtures where engineers, fabricators, technicians and quality teams compare force at a specific position, capture a maximum, or repeat the same test across multiple parts.
Spring Testing: Force at a Known Deflection
S-beam load cells are commonly used in spring test systems because they can measure both compression and tension. A useful spring test does more than record one force value: it pairs force with displacement. Compress or extend the spring to a known position, record the force, repeat at another position and compare the change. For a linear spring, the force-versus-displacement relationship can be used to estimate spring rate. For production work, the same approach can identify parts that fall outside an expected force window.
Cable, Cord and Strap Tension Testing
A cable or strap test works best when the specimen is connected inline so all tensile force travels through the load cell. The 100 lb range is useful for light cables, pull cords, elastic assemblies, straps, small chains and similar components. Fixtures should grip the specimen without slipping and should allow the S-beam to self-align instead of introducing bending. Peak Hold is particularly useful when the test objective is maximum pull or breakaway force.
Small Component Pull and Compression Checks
Manufacturing and repair shops can use a 100 lb force system to compare clips, latches, handles, connectors, springs, small mechanisms and assemblies. The goal may be to measure insertion force, extraction force, clamp force, breakaway force or the maximum force reached before a defined stop. A rigid test frame and repeatable alignment make these comparisons much more meaningful than hand-pulling with an uncontrolled angle.
Why Peak Hold Helps
Release events happen quickly. A clip can pop free, a cable can start moving, or a spring-loaded mechanism can pass a high-force point faster than an operator can read the display. Peak Hold preserves the maximum, making it easier to compare parts and document the result.
Build a Repeatable Fixture
Keep the force direction axial through the S-beam.
Use the same attachment points for every sample.
Control displacement or test position when comparing springs.
Use a consistent pull or compression rate when comparing peak forces.
Record environmental conditions if temperature meaningfully affects the component.
Calibration Matters More When Differences Are Small
When two components differ by only a fraction of a pound, a poorly aligned or unverified setup can overwhelm the difference you are trying to measure. Verify zero and one or more known force points before an important test series, especially after moving the fixture or changing attachments.
Related Search Questions
How do I measure spring force accurately?
Use a load cell inline with the spring force and control the spring’s displacement. Record force only after the fixture is stable and repeat the same positions for every sample.
Can one S-beam test tension and compression springs?
Yes. The sensor can measure both directions when the fixture is designed so the load remains axial.
Can I use it for cable break testing?
It can measure force up to its rated 100 lb capacity, but destructive tests require guarding and a fixture that contains released energy. Do not plan a test that may exceed the sensor capacity.
