There are many testing methods for ndt wire rope tester, including ultrasonic testing, ray testing, acoustic emission testing, eddy current testing, electromagnetic testing, mechanical testing, acoustic testing, current testing, optical testing, vibration testing, etc. Until recent years, electromagnetic testing is the main method in the testing of ndt wire rope tester, and the other non-destructive testing technology is still limited to the laboratory research stage.

In view of LF type defect of local damage, magnetic flux leakage detection principle is adopted, that is, the defect of wire rope is detected by leakage magnetic field at the broken wire of wire rope.

In view of LMA type defect of metal cross-section area loss, the main magnetic detection method is adopted, that is, the change of metal cross-section area of wire rope is detected by measuring the magnetic flux passing through the inside of wire rope.

According to the different working principle of electromagnetic detection method, its magnetization can be divided into AC magnetization, DC magnetization and permanent magnetization. Because of its small size, light weight, convenient use and low detection cost, especially the development and application of new permanent magnet materials in recent years, the advantages of permanent magnet magnetization detection device are more obvious, so a large number of permanent magnet magnetization methods are used in electromagnetic detection method.

The commonly used sensor types are Hall element sensor and induction coil. In practical use, the output signal of Hall sensor is not affected by the moving speed of sensor, and the volume of Hall element is small, which has great advantages in measuring small gap space magnetic field. Therefore, the ndt wire rope tester has been widely used.

Xzbelec colorimeter usage overview

It is used to measure the color produced by substances in a dissolved state. The instrument is calibrated using the platinum-cobalt color standard solution specified in the national standard GB5750, and the "degree" is used as the chromaticity measurement unit. It can also be widely used in color measurement of power plants, pure water plants, waterworks, domestic sewage treatment plants, beverage plants, environmental protection departments, industrial water, wine industry and pharmaceutical industry, epidemic prevention departments, hospitals and other departments.

3. It has a reliable positioning structure and a high-precision optical path system, and the instrument can work stably for a long time.

4. It has a high intensity long life light source. The user has no worries about replacement. It is stable and maintenance free.

It uses the photoelectric colorimetric principle, platinum-cobalt color standard solution for calibration, direct reading of the chromaticity value.

Ultraviolet light meter detects the intensity of ultraviolet radiation, and is used to measure the intensity of ultraviolet radiation in the fields of photochemistry, flaw detection, ultraviolet light source, plant cultivation, large-scale integrated circuit lithography, and polymer material aging.

Ultraviolet light is ultraviolet radiation, which is electromagnetic radiation with a wavelength of 100-400nm. It refers to the intensity of ultraviolet radiation per unit area. The instrument commonly used to detect the intensity of ultraviolet radiation is called an ultraviolet radiometer, also called an ultraviolet illuminance meter. Although it is called an illuminance meter, it has nothing to do with illuminance. Illumination studies the visible light that the human eye can see. The ultraviolet light meter measures ultraviolet light, which is invisible to the human eye, so it is related to the irradiance.

Irradiance is called radiant flux density and it is the integral of radiance to the solid angle. The area of the irradiance is integrated to obtain the power of the radiation.

Definition 1: Radiated energy projected onto a unit area per unit time.

Definition 2: The radiant energy received by an object on a unit time and unit surface. The unit is W / m2.

Definition 3: The radiant flux on an infinitely small bin containing the point divides the area of the bin.

Definition 4: Radiated energy projected onto a unit area per unit time. Irradiance (Ee, E) is a physical parameter, which is the amount of radiant energy received per unit area on a given surface. Unit: Watt / square meter.

The wavelengths measured by the UV radiometer are divided into UVA (320nm-380nm), UVB (280nm-320nm), and UVC(200nm-280nm). ShenZhen Xinzhibang UV Radiometer LS125 can detect UVC, UVB, UVA various wavelengths. It is widely used in sterilization, curing, pharmaceutical factory testing, sewage treatment, disease control center, non-destructive testing, welding arc testing, ultraviolet aging experiment testing and other industries.
