What Are Force Gages and Load Cells?
Force gages and load cells are measurement devices used to determine tensile or compressive force. They are commonly used in manufacturing, quality control, testing, research, and other applications where accurate force measurement is important.
A force gage typically combines a force sensor with an integrated electronic or mechanical indication. Digital force gages often include an integrated display and may be handheld or mounted to a test stand. Depending on the model, a force gage may measure compression, tension, or both.
A load cell is a transducer that converts applied force into an electrical output. Unlike a force gage with an integrated display, a standalone load cell typically requires an external indicator, data-acquisition system, test stand, or other measurement system to display or record the measurement.
Force gages and load cells are available in a wide range of capacities, configurations, performance specifications, and output types.
Common Force Measurement Equipment
SIMCO calibrates many types of force measurement equipment, including:
- Digital force gages
- Mechanical force gages
- Handheld force gages
- Tension force gages
- Compression force gages
- Tension and compression load cells
- S-beam load cells
- Pancake and low-profile load cells
- Button and miniature load cells
- In-line load cells
- Force transducers
- Force sensors
- Load cell indicators and related force measurement systems
Calibration capability may depend on the device type, force range, output, fixturing requirements, and applicable calibration specifications.
Force Gage and Load Cell Calibration Capabilities
Force calibration compares the response of a force gage, load cell, or force measurement system to known applied forces established through calibrated reference standards.
Depending on the equipment and calibration requirement, testing may include:
- Tension force
- Compression force
- Multiple measurement points across the operating range
- Increasing and decreasing force measurements
- Repeatability
- Zero response
- Indicated force for force gages and complete measurement systems
- Electrical output for applicable load cells and force transducers
For a force gage or complete force measurement system, calibration typically evaluates the indicated force directly. For a standalone load cell, calibration may characterize the relationship between applied force and the load cell’s electrical output.
Results may be reported in force units or, when requested and applicable, in electrical output such as mV/V, depending on the device and calibration requirement.
Calibration methods and test points are selected based on the instrument design, manufacturer requirements, applicable specifications, and requested calibration scope.
Why Force Gage and Load Cell Calibration Matters
Force measurements are used to make decisions throughout manufacturing, inspection, product testing, and engineering. An inaccurate force measurement can affect product acceptance, process settings, material testing, assembly performance, and engineering conclusions.
Regular calibration provides objective evidence of how a force gage or load cell is performing at the time of calibration.
Calibration can help organizations:
- Confirm measurement performance against applicable requirements
- Identify changes in sensitivity or measurement response
- Maintain metrological traceability
- Support product and process quality
- Meet customer, quality-system, and regulatory requirements
- Evaluate measurement uncertainty and measurement risk
- Maintain documented measurement records
Metrological traceability is the documented path that connects a measurement result and its associated uncertainty to recognized reference standards through an unbroken chain of calibrations.
SIMCO calibrations provide traceability to the SI, typically through NIST or other national metrology institutes.
Calibration Service Options
SIMCO provides force calibration services for a wide range of force gages, load cells, force transducers, and related measurement equipment.
Depending on equipment type and capability, services may include:
