Overview
The SN-500 Force Gauge is a Dial tension and compression Force Gauge of the SUNDOO brand, model SN-500. It is a small and simple thrust and tension testing instrument with the advantages of High Accuracy, easy operation and easy portability. It is equipped with a peak switching operation knob, which can indicate the peak load and continuous load value, and has a tolerance belt indicator device to facilitate batch test readings. It is suitable for push-pull load testing in Electronics, Light Industry Spinning & Weaving, Construction Hardware, Lighters and Ignition Devices, Fire Equipment, Pen Making, Locking, Fishing Tackle, Power Machinery, Scientific Research Institutions and other industries. It is a new generation of products to replace Tubular Force Gauge.
Features
1. Handheld design, compact size, simple operation, and can be used in combination with various fixtures.
2. Pointer indication, easy reading, high test Accuracy;
3. Peak protection function and continuous load indication can be switched freely.
4. Tolerance belt indicator device, which can achieve upper and lower limit setting;
5. Newton and kilogram units (units can be customized) are displayed at the same time, without unit conversion;
6. One-year warranty, long-term maintenance;
7. Design patent, patent number: ZL200520074355.1.
Principle
The Force Gauge indicates the load value through the pointer, and the user can operate the switching knob to switch between peak load and continuous load mode. During testing, the test object and the Force Gauge are aligned to apply thrust or tension, and the internal spring plate and pointer mechanism of the instrument respond to load changes to display the exact load value. The tolerance indicator belt can set the upper and lower limits, which is convenient for quickly judging whether it is qualified or not during batch testing.
Applications
Electronics, Light Industry Spinning & weaving, Construction Hardware, Lighters and Ignition Devices, Fire Equipment, Pen Making, Lock Making, Fishing Tackle, Power Machinery, Scientific Research Institutions
Steps
1. Select the appropriate test joint fixture and install it on the Force Gauge.
2. Tensile test: Install the attached tensile fixture to the central shaft marking the pull [PULL] end;
3. Compression test: from the attached thrust fixture, select the appropriate test fixture and install it on the central shaft marked with the [PUSH] end.
4. Utilization of the extended connecting rod: When the test object cannot be contacted, use the attached extended connecting rod to install the fixture to ensure that the test object is on the same line as the Force Gauge;
5. Switch knob operation: Gently press the switch knob and turn left to the continuous load [TRACK] position, or turn right to the peak load [PEAK] position. After the test, the knob should be placed in the peak load [PEAK] position;
6. Dial adjustment: swirl/spin scale adjustment circle to align the pointer with the dial [0] position, if the pointer deviates from the [0] position when placed vertically, it needs to be adjusted and tested;
7. Tolerance indicator belt setting: Rotate the two pointers on the tolerance indicator to set the upper and lower limits. During the test, the pointer is qualified within the range, otherwise it is unqualified.
Notice
Please read the instructions carefully before testing to ensure correct operation.
When testing, please align the object under test with the Force Gauge, otherwise the correct load value cannot be obtained.
- When using the extended connecting rod, the object to be tested and the Force Gauge must be in the same straight line.
- Please place the "·" mark of the switching knob in the peak load [PEAK] position after the test is completed, and avoid placing the continuous load [TRACK] position for a long time to prolong the life of the internal spring leaf;
- When placed vertically, if the pointer deviates from the [0] position, the swirl/spin scale adjustment circle should be aligned with the [0] position before testing;
- Optional test benches need to be purchased separately.
