Metrix+ DFG Series Digital Force Gauge Push Pull Tension Compression Tester

A. Product Overview

The Metrix Plus DFG Series Digital Force Gauge Push Pull Tension Compression Tester is designed for measuring both tensile pulling force and compression pushing force across industrial, laboratory and quality control applications.

The series uses an internal strain gauge load cell to convert applied mechanical force into an electronic measurement. This provides digital force readings and allows users to monitor changing loads as well as capture the maximum force reached during a test.

The DFG Series is available in four force capacities:

DFG 2D: 2 kgf, 19.6 N, 4.4 lbf
DFG 20D: 20 kgf, 196 N, 44 lbf
DFG 50D: 50 kgf, 490 N, 110 lbf
DFG 100D: 100 kgf, 980 N, 220 lbf

Users can select between three commonly used force measurement units:

• Newton
• Kilogram force
• Pound force

The reversible backlit LCD automatically provides convenient viewing when the force gauge is used handheld or mounted vertically on a test stand.

The instrument also includes interchangeable attachments such as pulling hooks, flat compression tips, cone tips and V shaped accessories for different force testing applications.

B. Working Principle

The Metrix Plus DFG Digital Force Gauge works using a strain gauge load cell.

When a pushing or pulling force is applied to the measuring shaft, the internal load cell experiences a very small mechanical deformation.

The strain gauge detects this deformation and converts it into an electrical signal. The instrument processes the signal and calculates the corresponding force value.

The measured result is then displayed in the selected unit:

• Newton
• Kilogram force
• Pound force

The gauge can operate in two main measurement modes.

Track Mode

Track Mode continuously displays the force being applied in real time.

For example, if the user gradually compresses a spring, the displayed reading changes continuously as the compression force increases or decreases.

Peak Mode

Peak Mode captures and retains the highest force recorded during the test.

This is particularly useful for applications such as:

• Wire pull out testing
• Breaking force measurement
• Connector extraction testing
• Spring force testing
• Packaging seal testing
• Latch release force testing

The interchangeable attachments allow the same instrument to perform different tension and compression measurements.

C. Why Is the Metrix Plus DFG Series Used?

Force is an important quality parameter in many manufacturing and engineering applications.

A component may look correct visually but still fail if its insertion force, pulling force, compression force or breaking force does not meet the required specification.

The Metrix Plus DFG Series allows users to measure these mechanical forces numerically.

It can be used to:

• Measure push force
• Measure pull force
• Perform tension testing
• Perform compression testing
• Check maximum breaking force
• Test springs
• Measure connector insertion force
• Measure connector extraction force
• Test electrical switch actuation force
• Perform wire terminal pull tests
• Check crimp connection strength
• Test door and latch mechanisms
• Measure packaging seal peel force
• Test zipper operating force
• Evaluate component strength
• Perform incoming material inspection
• Conduct production quality control
• Compare product samples
• Verify assembly consistency

Using a digital force gauge helps manufacturers establish measurable acceptance limits rather than relying only on manual feel or visual inspection.
