Eddy current thickness gauge:Eddy current thickness gauges are generally used to measure the thickness of an insulating coating on a non-ferrous metal substrate. This method is also a non-destructive measurement method.The instrument uses a thin wire coil that conducts high frequency AC (above 1 MHz

Coating thickness gauge is an important process parameter and plays an important role in the product quality, process control and cost control. Now, technicians can use many different kinds of instruments and methods to measure the thickness of a coating or film. There are many factors to consider w

The principle of magnetic induction is to measure the thickness of the coating by using the magnetic flux of the probe through the non-ferromagnetic coating into the iron substrate. The thicker coating, the smaller is the magnetic flux. Because it is an electronic instrument, it is easy to calibrate

Principle of magnetic attraction force measurementThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating. Using this principle to make a thickness gauge, measurement can be

The ultrasonic thickness gauge and coating thickness gauge independently developed by PIEZOHANNAS Co., Ltd. have passed ISO9000 and CMC certification, and the product series are available in many varieties and specifications. The products are exported to many countries and regions and are one of the

The high frequency AC signal generates an electromagnetic field in the probe coil, and a vortex is formed therein when the probe is close to the conductor. The closer the probe is to the conductive to substrate, the larger the eddy current and the greater the reflection impedance. This feedback acti

Principle of magnetic suction measurement and thickness gaugeThe amount of suction between the permanent magnet (probe) and the magnetically permeable steel is proportional to the distance between the two, which is the thickness of the coating thickness measurement gauge. Using this principle to mak

Ultra-thin materialWith any ultrasonic thickness gauge, when the thickness of the material is being tested below the probe's lower limit of use, measurement errors will result, and if necessary, the minimum limit thickness can be measured by the test block comparison method.When it is measuring ultr

A protective layer that protects the surface of the material, such as coatings, coatings, overlays, chemically formed films, etc., which is referred to as coating in some national and international standards.Coating thickness measurement gauge has become an important part of the processing industry

Several methods in measurement1—Single measurement method: measurement at one point2—Double measurement method: Perform two measurements with a probe at one point. The probe crosstalk spacers should be perpendicular to each other in both measurements. Selecting the minimum value in the reading as th

The principle of ultrasonic thickness gauge measurement is similar to the principle of light wave measurement. The ultrasonic pulse emitted by the probe reaches the back-test object and propagates through the object. When it reaches the material interface, it is reflected back to the probe. The thic

The ultrasonic cleaner transducer is a key component in the cleaning machine, and its quality directly affects the cleaning effect.(1) DesignThe front cover of the transducer for the ultrasonic cleaner is horn-shaped for matching with the water load. From the design requirements, the cleaning transd
