Overview
The SN-20 Force Gauge is a small and simple thrust and tension test instrument produced by SUNDOO. It has the advantages of High Accuracy, easy operation and easy portability. The instrument is equipped with a peak switching operation knob, which can indicate the peak load and continuous load value. It is equipped with 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. Patent design, patent number: ZL200520074355.1.
Principle
Force Gauge places the test object in a straight line with the instrument by installing a suitable fixture for push-pull load testing. There is a peak switching knob inside the instrument, which can switch between peak load and continuous load mode, and indicates the load value on the dial through the pointer. The tolerance indicator belt allows the user to set the upper and lower limits. When the pointer is within the set range, it means that the test is qualified, and when it is outside the range, it means that it is not qualified.
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. Test preparation: Select the appropriate test connector fixture and install it on the Force Gauge.
2. Tensile test: Install the attached tensile fixture onto 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 extended connecting rod: When the test object cannot be contacted, use the attached extended connecting rod to install the fixture.
5. Confirmation and operation method of switching knob: Gently press the switching knob down and turn it to the left at the same time, so that the "·" mark of the knob is at the continuous load [TRACK] position; or turn it in the right direction, so that the knob pops up, and the "·" mark is at the peak load [PEAK] position. Please place the "·" mark of the switching knob at the peak load [PEAK] position after the test is completed.
6. Dial adjustment: swirl/spin scale adjustment circle, so that the pointer is aligned with the [0] position of the dial.
7. Tolerance indicator belt setting: Turn the two pointers on the tolerance indicator to set the upper and lower tolerance limits required for the test.
Notice
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 for testing, the test object and the Force Gauge must be in the same line, otherwise the correct load value cannot be obtained.
• After the test is completed, please place the "·" mark of the switching knob in the peak load [PEAK] position. If it is placed in the continuous load [TRACK] position for a long time, the service life of the internal zero spring will be shortened.
• When the instrument is placed vertically, even if no load is applied, the pointer may deviate from the [0] position due to its own weight. The swirl/spin scale should be adjusted to align the [0] of the dial with the pointer before testing.
