A force meter is an instrument used to measure the acceleration and the rotation of a physical object. It is used for any application in which the object needs to be tested; measured data can be measured to have information about the object. Some examples are testing the horizontal and vertical capabilities of a product or anything on a production line, analyzing vehicle performance on the road and so on.
The force meter is a device that is mounted on a tripod and is attached to the object being tested. The technician usually carries a meter cord. To the extent possible, the technician should not have to leave the place where the test is to be done. Since the force meter can detect any variations in the force exerted on the object, it will provide the technician with data and an indication of the variation of the force over a specific period of time.
Depending on the requirements of the test results, the following are some factors to be considered: the time duration of the test, the depth of the test, the applied force (g), the centre of gravity of the object (CG), the distance from the mains power source, etc. The results are displayed in terms of force applied at different moment rates. For example, a current is created in the object under test by changing the moment rate of force, and these changes are displayed in the chart. The range of moment rates is also used to compare the performance of different objects.
The force meter uses the G-force index as a guide. The greater the index, the higher the force that is applied and the longer the test duration. Hence, the maximum force level is reached, and the force at which the object failed to perform the test is also recorded. An object which does not show up as failing to perform a test should, therefore, be taken to mean that the object can be done with lesser force and it is just that it is not exceeding this limit.
Force meter features include readout display, a digital display that can be used to check the data or the objects in real-time, etc. If the unit is calibrated, it will automatically adjust the force it uses for the test, thereby enabling the technician to perform the test with a greater force and thus ensure that the object is not breaking or sagging due to pressure.
Various features, such as rotating force meter, holding force meter, mechanical force meter, power meter, etc., can be used depending on the requirements of the test. However, the rotary force meter is most suitable for testing products which have attachments like Velcro, hooks, brackets and hooks with a spinning action. All the other force meters can be used for testing plastic and metal objects.
