Mark-10 Corporation is an independent, family-run business that designs
and manufactures force and torque measurement products. Force measurement is an
invaluable tool for manufacturers and Mark-10 products are used in various
industries such as automotive, medical, textile, pharmaceutical, cosmetic,
packaging, and food.
Mark-10 products can be
used in a virtually limitless number of tension and compression force testing
applications. Various items and materials can be tested such as springs, wires
and cables, connectors, caps, and mechanical components and assemblies.
Mark-10 Corporation has a wide variety of instruments necessary for a force testing system,
from digital indicators, test stands, grips, and data collection software.
Mark-10 Force Gauges have many useful
features such as Peak/hold readings, selectable
units of measurement, full-scale load bar, and setpoints with high/low limit
indicators. They have a broad range of capacities available from 50 grams
to 2,000 lbs of force full scale. Typical overload protection for most of the
Force Gauges is at least 150% of capacity.
Mark-10 Force Gauges may
be used by hand for light force measurements or used with a force test stand
and gripping fixtures to create a complete testing solution for large force
measurements or when higher accuracies are needed.
Test stands and grip
attachments are an important part of a force testing system. Test stands are
useful in eliminating inconsistencies inherent in hand testing and can help to
automate test and manufacturing processes. Grip attachments mount to most Mark-10
force gauges with a quick-change convenience and can assist in maintaining
Mark-10 Force Gauge Calibration
Mark-10 Force Gauges are
typically calibrated by comparing the Force Gauge indication to a known force
For gauges under 200 lbs, Mark-10 Force Gauges
are usually calibrated by using calibrated weights suspended from a weight
hanger. An L-shaped bracket attached to a bench is sufficient to attach the
Force Gauge for the stability of the test. For gauges with higher capacities, other
reference standards such as load cells with digital indicators will be required.
Mounting the Force Gauge into a test stand at these higher capacities will
significantly assist in the alignment of the Force Gauge and standard and allow
the calibration to be performed safely.
The Force Gauge should be calibrated at a minimum
of every 20% of the full-scale capacity of the gauge to ensure the linearity of
the load cell is accurate throughout its full-scale range. The Force Gauge
display should indicate the force standard value within the stated
manufacturer’s specifications. If adjustment is required, a number of Force
Gauges have calibration functions that will realign the gauge when a specific
force, typically a full scale or near full-scale value, is applied.
The recommended calibration interval for Force Gauges is one year, however, calibration should be performed more frequently if the gauge was severely mishandled or dropped, is used in hazardous environments or is suspected of being overloaded.
