5. Working principle

The determination of cable force is divided into two types: interventional and non-interventional. The so-called interventional force measurement refers to connecting a tension sensor in series at the end or span of the cable, and directly reading the cable force. This is the most accurate and intuitive force measurement method, as shown below 1, 2 shows.

The input of this force measurement method is large, and it is only suitable for experimental research and individual projects with large tonnage and high requirements. It is not suitable for prestressed structural projects with large amount of cable.

There are also two methods of non-intrusive force measurement. One is the vibration frequency measurement method, that is, the natural vibration period T of the cable is a function of the tension H, the length L of the cable, and the mass W of the cable. From the formula, the measured The cable's vibration period T can calculate the tensile force H in the cable. The principle is relatively simple, but the seismic signal is converted into a signal, and the cable force value is output after being processed by the computer. This process requires many instruments and equipment, which makes it difficult for workers to master, and is not convenient for working at heights. In addition, the supporting conditions of the cable end have an impact on the vibration period and the accuracy of the cable force measurement. Another principle for measuring the cable force is based on mechanical principles. As shown in the figure below, there is a functional relationship between the lateral displacement δ of the cable force and the tensile force H, lateral force P of the cable and the length of the cable. When the displacement maintains a certain value, the greater the cable tension H, the greater the lateral force P.

Picture 42.png

The force sensor outputs the lateral force P, which is converted into cable tension after being processed by the microprocessor, and then displayed on the LCD. The above principle is also relatively simple, but the relationship between the lateral force and the cable force is still related to the diameter of the cable, the cross-sectional structure. The elongation of the rope and the size of the tensile force, etc. We use the correction and accurate calibration of the microprocessor After getting the correct and stable cable. Can pass the test and inspection, has reached the level of similar foreign products.

2. MEM display

When data is stored in memory, \"MEM \" will be displayed. When you press \"Save \" to view the memory data, \"MEM \" flashes.

3. Unit display

The letters \"K \" are combined with \"N \", \"kgf \", \"lbf \" to form \"KN (thousand of cattle) \", \"t (tons) \", \"Klb (Thousand pounds) \"As shown:

4. MAX, MIN display

When the measured value is greater than the MAX value, MAX is displayed;

When the measured value is less than the MIN value, MIN is displayed.

Incorrect operation may damage the instrument or cause serious accidents. This manual points out important matters for preventing accidents and how to use the instrument. Please read this manual carefully before use, and keep it properly after reading, so that you can read it again.

If you are testing the impact load, please select the model whose MAX load is twice the impact load to be tested.

Warning matters

1. Do not use the instrument beyond the MAX range. Otherwise, the sensor may be damaged or even an accident may occur.

2. When the test value exceeds the range, the buzzer will beep continuously, at this time, please quickly release the added load or reduce the load.

Safety Precautions

1. Please use the matching charger to charge, otherwise it will cause circuit failure and even fire.

2. Do not use a power supply other than the rated voltage of the charger, otherwise it may cause electric shock or fire.

3. Do not pull out or insert the plug with wet hands, otherwise it may cause electric shock.

4. Do not pull the plug of the charger's power cord to pull out the plug, so as to prevent the cord from being broken and being shocked.

5. Please clean the machine with a soft cloth. Immerse the cloth in water soaked with detergent and wring it out to remove dust and dirt.

Note: Do not use volatile chemicals to clean the machine (such as volatile agent, thinner, alcohol, etc.)
