Other brief introductions about thickness gauges:

Commonly used thickness gauges include nuclear radiation thickness gauge, X-ray thickness gauge, high frequency eddy current thickness gauge and microwave thickness gauge.

Nuclear radiation thickness gauge:

The radiation emitted by the radioactive source penetrates the material to be tested and is absorbed by the detector. The detector generates a current IX corresponding to the thickness. Its voltage drop on R is EX, which is compared with the voltage ES corresponding to the thickness set by the setter After that, the deviation (that is, the thickness change) is amplified and sent to the display instrument or adjustment instrument for display or control. Thickness gauges that use beta rays as a radioactive source have a narrow measuring range and are suitable for measuring the thickness of thinner steel strips, copper strips, paper, plastics and rubber. Thickness gauges that use gamma rays as a radioactive source have a wide measurement range and can be used in harsh environments without being affected by smoke, steam, and moisture, but they need to take protective measures against nuclear radiation.

X-ray thickness gauge:

The working principle of the X-ray thickness gauge is to determine the thickness by measuring the intensity of the X-rays transmitted through the sheet. The X-ray beam is thin and the response speed is fast. The X-ray disappears immediately after the power is turned off. Therefore, the use and storage of this thickness gauge are more convenient and safer than the nuclear radiation type, and the error caused by the possible water film on the surface of the measured plate is relatively small.

Microwave thickness gauge:

The working principle of the microwave thickness gauge is that microwaves are emitted from the measuring circuit to the two surfaces of the material to be measured in turn, and then sent to the receiver for measuring the reflected wave after reflection. When the thickness of the measured material changes, the length of the microwave in the measuring loop also changes. After it is compared with the signal of the set compensation circuit, it is detected and output. The microwave thickness gauge can achieve non-contact measurement and is not affected by the properties of the material being measured. The disadvantage is that it is greatly affected by the surrounding water vapor.

Ultrasonic thickness gauge:

A company in the United States has manufactured an Ultrasonic Thickness Gauge (UTG) to measure the thickness of pipes seen during processing and water treatment plants. It can give 100 hours of Rien Promise measurement with an accuracy of plus or minus 0.01 inches. Its optional probe can measure curved surfaces with a radius as small as 10 mm.

Special Note:

As this hand-held thickness gauge is in use, its hand-held parts and detection parts (referring to the handle and probe) are often worn out, which is extremely prone to loss (most customers respond that it is easily damaged due to the high frequency of use). Based on the exquisite design principle, the company built precision parts in the original dial, and coordinated the accuracy to reduce the number of wearing main parts and replace the easily worn probe into stainless steel to increase its service life. Many cooperative companies are satisfied and have chosen this product many times, saving costs in details and improving work efficiency for enterprises!
