Force Gauge

A force gauge, also known as a push-pull scale, is a handheld or test-stand instrument designed to measure push and pull forces with accuracy. It is commonly used in laboratories, quality control, and manufacturing processes to evaluate tensile strength, compression force, peel strength, and friction.

Types of Force Gauges

There are various types of force meters. The ATO force gauge series includes multiple types (such as digital, mechanical, and spring) that can meet different testing requirements.

Digital Force Gauges: Feature internal load cells and digital displays.

• High accuracy
• Fast sampling rate
• Peak force capture
• USB data logging to PC

Mechanical Force Gauges: Utilize a calibrated spring mechanism to display force via a dial.

• Durable construction
• No batteries required
• Quick and easy measurements

Spring Force Gauges: Use an internal spring system to measure force based on displacement.

• Simple force measurement
• Cost-effective solution
• Suitable for basic testing tasks
• Lower precision requirements

Pro tip: Spring Force Gauges fall under the mechanical force gauge category. ATO’s standalone spring force gauges adopt internal spring displacement for force detection, sharing core spring-driven measurement principles with dial mechanical models while serving low-cost, basic push-pull test scenarios separately.

Industrial Applications of Force Gauges

Force gauges are widely used across different industries to evaluate material performance, product quality, and mechanical behavior under applied force.

• Tensile strength testing: Used to check how much pulling force materials like wire, plastic parts, or textile samples can withstand before failure.
• Adhesion and peel testing: Measures how strongly adhesives, labels, or tapes stick to different surfaces, commonly used in packaging and product validation.
• Button and switch force testing: Evaluates the pressing force of keys, switches, and control interfaces to ensure consistent feel and proper actuation in devices.
• Spring load testing: Assesses how springs respond under compression or tension, helping confirm performance and durability in mechanical assemblies.

Guide to Select Measuring Range for Digital Push-Pull Force Gauge

A digital push-pull force gauge is a precision instrument used to measure tensile (pull) and compressive (push) forces in various applications such as quality control, material testing, and assembly processes. Choosing the correct measuring range is critical to ensure accurate readings and protect the instrument from damage.

Follow the Core Range Selection Rule
Before choosing a force gauge, determine the maximum force expected during testing. As a general rule, the force gauge's full-scale capacity should be:

• Full Scale Range = 1.2–1.5 × Maximum Expected Test Force
  
• This safety margin protects the load cell from accidental overload while maintaining good measurement accuracy.

Best Operating Zone
For optimal performance, keep normal test forces within 20% to 80% of the gauge's full-scale capacity. Most digital force gauges achieve their best balance of accuracy and resolution within this range.
Example: If the maximum insertion or pull-out force of a connector is 80 N:

• Recommended gauge range: 100 N
• Calculation: 80 N × 1.25 = 100 N
• Result: The working force remains within the recommended operating zone, ensuring accurate measurements and overload protection.

Distinguish Static vs Dynamic Test Load
Testing load falls into static and dynamic categories, which require different safety factors when sizing the force gauge range:

• Static test (constant force: spring compression, switch pressing): Reserve 1.2× max force as safety allowance.
• Dynamic/impact test (peel force, snap pull, quick stamping): Choose 1.4~1.5× max force, instantaneous shock force easily exceeds nominal load.
• For dynamic applications, choose a gauge rated at 1.4–1.5 times the maximum expected force to accommodate sudden peak loads.

Match Minimum Measured Force with Resolution
Range directly decides display resolution:

• Small-range gauge (10N/50N): High fine resolution (0.01N/0.1N), perfect for tiny force: key switch, micro-spring, electronic terminal insertion.
• Large-range gauge (1kN/5kN): Coarse resolution (1N/10N), for heavy-duty test: hardware tension, automotive part pull-off.
• Rule: Your minimum test force should be ≥5× gauge resolution to eliminate reading error.
