Sundoo SN-200 Push-Pull Force Gauge is a precision measuring device manufactured by Sundoo – a reputable brand in the field of force measuring and testing equipment popular in the Asian market. The SN-200 model is specially designed to measure the value of applied force in two directions: tension and compression, with a maximum measurement capacity of up to 200 Newtons (N), equivalent to approximately 20.4 Kilogram-force (kgf) or 45 Pound-force (lbf). This is an essential tool widely used in quality control, research and development, material testing, and manufacturing processes requiring force precision.
Operating Principle:
The Sundoo SN-200 push-pull force gauge operates based on the principle of using an internal Load Cell. Load cells typically use Strain Gauges attached to a metal structure (usually aluminum alloy or steel).
- When a tensile or compressive force is applied to the measuring head of the device, the metal structure inside the load cell deforms slightly in proportion to the applied force.
- The strain gauges (which are resistors highly sensitive to shape changes) attached to this structure change their electrical resistance corresponding to the degree of deformation.
- The internal electronic circuit of the device measures this small change in resistance and converts it into an electrical voltage signal corresponding to the force value.
- This voltage signal is processed, amplified, and converted into digital data.
- The corresponding force value is displayed on the digital screen in the selected measuring unit (N, kgf, lbf).
Highlights of the Sundoo SN-200 Push-Pull Force Gauge:
- Two-Way Tension and Compression Measurement: Flexible measurement capability in both directions of force application (pulling out and pushing in) on a single device, serving diverse testing needs.
- Maximum Load Capacity of 200N: Allows measuring force values up to 200 Newtons, suitable for testing forces of materials, components, or products with moderate durability. The machine supports displaying results in multiple common measurement units such as N, kgf, lbf and can easily convert between these units.
- Clear Digital Screen: Equipped with a numeric LCD screen displaying the measured force value intuitively and accurately. The screen usually has a backlight, making it easy to read results even in low-light conditions.
- Peak Hold Function: The device has the ability to automatically "freeze" and display the maximum (peak) force value achieved throughout the testing process. This function is extremely useful when performing destructive tests (measuring material breaking tensile force) or tests requiring the determination of maximum compressive/tensile force applied.
- Reliable Accuracy: Provides measurement results with specified accuracy (usually about ±0.5% of full scale), reliable enough for quality control and routine testing applications.
- Multiple Measuring Modes: Supports real-time measuring mode (REAL TIME), displaying the instantaneous applied force value, and peak hold mode (PEAK), displaying the maximum force value achieved.
- Diverse Accessories: Comes with standard accessories such as hook heads, compression heads (flat, pointed, round...), helping you connect the device to samples of different shapes or apply force to different test points conveniently.
- Compact, Portable Design: The device has a compact size, light weight, easy to grip and operate directly by hand at many different locations on the production line or in the laboratory. The device can also be mounted fixedly on specialized testing stands.
- Data Connection Port (Optional/Version): Some versions or models of Sundoo SN-200 can be equipped with communication ports (e.g., USB, RS232) to connect to a computer, allowing transmission of measurement data, result collection, and report generation via supporting software.
With the ability to accurately measure tension and compression forces up to 200N, Sundoo SN-200 Force Gauge is widely applied in many industries and fields:
- Quality Control (QC):
- Measuring pressing force of buttons, switches on electronic devices, home appliances.
- Measuring opening/closing force of bottle caps, packaging, boxes.
- Measuring breaking tensile force of small wires, cables, threads, fabrics, small spot welds.
- Measuring peel strength of adhesive tapes, glues, labels.
- Measuring compressive force of soft materials, foams, small springs.
- Testing insertion/withdrawal force of connectors, pins.
- Testing initial friction force or sliding force.
- Research and Development (R&D): Testing force characteristics of prototype product samples, new materials.
- Manufacturing: Testing assembly force, pressing force in production processes requiring precise force control.
- Education and Training: Used in physics and engineering laboratories to illustrate force laws and practice measurement.
Important Notes for Use: To ensure accuracy, durability, and safety when using the Sundoo SN-200 Force Gauge, note the following:
- ABSOLUTELY DO NOT EXCEED MAXIMUM LOAD CAPACITY (200N): This is the MOST IMPORTANT rule. Applying tensile or compressive force exceeding 200 Newtons to the measuring head will cause overload and permanently damage the internal load cell. Estimate the force to be measured before use and choose a machine with a suitable load capacity.
- Apply Force Along the Correct Axis: Always apply tensile or compressive force along the exact axis aligned with the measuring head of the device. Avoid applying oblique force (misaligned force), bending force (bending the measuring head), or torsional force to the measuring head, as these types of forces can damage the load cell even if the total force does not exceed the 200N maximum load.
- Use Appropriate and Secure Accessories: Always choose the correct accompanying accessories (hooks, compression heads...) suitable for the test and ensure the accessories are securely attached to both the machine and the test specimen.
- Apply Force Smoothly, Avoid Impacts: Apply force gradually, progressively, and smoothly. Avoid sudden jerks, heavy impacts, or dropping heavy objects onto the measuring head.
- Periodic Calibration: Digital force gauges, after a period of use or according to the manufacturer's recommendation, need periodic calibration (usually once a year) at certified laboratories to ensure measurement accuracy remains within allowable limits.
- Operating and Storage Environment: Use and store the device in temperature and humidity conditions specified by the manufacturer. Avoid excessively hot, cold, humid, dusty environments, or corrosive chemicals. Avoid vibrations, strong magnetic fields, or heavy impacts.
- Battery: Monitor battery status. Charge or replace the battery promptly when the device indicates low battery to ensure stable operation.
Sundoo SN-200 Push-Pull Force Gauge is a reliable, accurate, and easy-to-use digital force measuring device, suitable for many tension and compression measurement applications with a maximum load capacity of 200N. With clear digital display, convenient peak hold function, good accuracy, and compact design, this product is an essential tool for quality control (QC), research and development (R&D) departments, and production processes requiring fast and accurate impact force testing.
