What is the specific operation process of the tensiometer?

Tensiometer fast and reliable quality control mode. After setting the measurement parameters, the surface tension value can be accurately measured and displayed. The ability to independently set the measurement range, the number of test data, and the average value of the measurement is the ideal tool for R&D.

In practice, dynamic tensiometers are more widely used because they can simulate the migration of surfactants. Professional measuring instrument for measuring the surface tension value of liquids, through the principles of platinum plate method, platinum ring method, maximum bubble method, hanging drop method, drop volume method and drip weight method, etc., to achieve accurate measurement of the surface tension value of liquids. At the same time, it is possible to measure the value of the surface tension that varies with time using software technology.

The force acting on the surface of the liquid, causing the surface area of the liquid to shrink, is known as the liquid surface tension. The reason for this is that there is a thin layer on the surface of the liquid in contact with the gas, called the surface layer, and the molecules in the surface layer are sparser than the inside of the liquid, and the distance between the molecules is larger than that inside the liquid, and the interaction between the molecules is shown by gravity. For example, if you want to pull a spring apart, the spring will have a tendency to shrink.

The basic principle of the ring method is to remove the metal ring immersed in the liquid surface from the liquid surface, and the maximum tensile force required is equal to the product of the weight of the ring itself plus the surface tension and the circumference of the liquid surface to be removed.

Liquid surface tension tutorial.

Tensiometer refers to an instrument that measures the tightness of wires and strips, such as yarn, steel wire, copper wire, cable, steel cable, film, bundle material, aluminum foil and other materials in static or dynamic state. It provides accurate and quantitative tension parameters for the production process, ensuring that the tension remains stable or reaches the required value during the production process.

The tensiometer, like all instruments, will have a certain error and a certain measurement range even if the accuracy of the instrument is high. In general, the maximum tension used is 80% of the range of the tensiometer. Here's why:

Tensiometer calibration is usually done using a 2-point gauge method. The first point is 0 point, and the second point is 80% of the range, so theoretically speaking, the two most accurate points for tensiometer measurement are 0 point and the validity point. 2 Method for selecting the wire diameter range of the material measured by the tensiometer:

Since the tensiometer adopts the method of 2-point linear calibration, and the working principle of the tensiometer is to measure the resultant force (pressure on the measuring point) and convert the component force (material tension) through the parallelogram rule. In this way, if the calibration diameter of the tensiometer is different from the diameter of the material at the time of actual measurement, there must be an error in the measured value in theory, and the greater the difference between the diameter of the measured material and the standard diameter, the greater the measurement error. Therefore, when selecting the tensiometer, try to make the diameter of the measured material the same or close to the effective diameter of the tensiometer.

3 Calibration function of tensiometer: The calibration function of some brands of tensiometer on the market is open, and the calibration function of some brands of tensiometer is closed (only the manufacturer can use it). If the calibration function of the tensiometer is open, if the diameter of the material measured by the customer is different or different from the calibration diameter of the tensiometer at the time of selection, the customer can calibrate with the material being measured, and the calibration is very simple.

If the calibration function of the tensiometer is closed, then when selecting the tensiometer, the applicable wire diameter range of the tensiometer must be small, so that the measurement will be accurate, if the diameter range of the material you are measuring is large, you need to order multiple tensiometers corresponding to different diameters. 4 Calibration method of tensiometer: use 2-point calibration:

When the tensiometer is not subjected to any tension, the reading of the tensiometer is adjusted to 0 point, and then a weight equivalent to 80% of the range of the tensiometer (if the tensiometer range is 10 kg, 8 kg of weight) or a weight slightly greater than the tension of the material, hang it below the measured material, and then hang the other end of the measured material, at this time, the tension of the measured material is the weight of the weight. Now, the tensiometer is used to measure the tension of the material to be measured, and the tension value of the tensiometer is adjusted to the force equal to the weight of the weight, so that the calibration of the tensiometer is completed. If the calibration function of the tensiometer is open, then the customer can choose the range when choosing the tensiometer, of course, if the diameter of the material to be measured is only one, it is the best choice to let the manufacturer calibrate the factory exactly according to the diameter of your material.

If the diameter of the material you are measuring is small and you are not particularly demanding on accuracy, you can have the manufacturer calibrate to the median of the diameter of the material.
