[0002] A thickness gauge is used to measure the thickness of various materials, objects, and various processed parts. It can also monitor various pipelines and pressure vessels in production equipment to monitor the degree of thinning after corrosion during their use. It is widely used in various fields such as petroleum, chemical industry, metallurgy, shipbuilding, aviation, and aerospace, and requires extremely high accuracy. According to different measurement methods, thickness gauges can be roughly divided into contact thickness gauges and non-contact thickness gauges.

[0003] A high-temperature thickness gauge introduces ultrasonic waves into the equipment body through a probe and requires a high-temperature coupling agent to support. However, during the thickness measurement process, pipelines with too high temperatures are often encountered. The too high temperature is likely to cause damage to the probe or reduce its service life. Currently, on-site high-temperature thickness measurement cannot effectively cool the probe of the thickness gauge, affecting the subsequent use of the high-temperature thickness gauge.

[0004] Currently, during on-site high-temperature thickness measurement, the probe of the thickness gauge cannot be effectively cooled. After detection, the probe needs to be cooled for a period of time to avoid affecting subsequent use, reducing the detection efficiency; during the thickness measurement process, when detecting pipelines with too high temperatures, the too high temperature is likely to cause damage to the probe or reduce its service life, increasing the detection cost.

[0027] The utility model can enhance the high-temperature resistance performance of the high-temperature probe 3 in a high-temperature environment and protect the internal components 32 from the influence of high temperature by arranging a carbon steel pad 33 on the outer side of the shell 31 of the high-temperature probe 3; the inner side of the shell 31 is filled with an acoustic insulation material 312 and a heat insulation material 313. The acoustic insulation material 312 can reduce signal interference and ensure the stable transmission of measurement signals; the heat insulation material 313 further prevents high temperature from being transmitted to the internal components 32, improving the stability and measurement accuracy of the high-temperature probe 3; the design that the transmitting wafer 322 and the receiving wafer 323 are inclined inward at a certain angle helps to receive and transmit signals more accurately and optimize the measurement effect; the setting of the temperature sensing module 324 can monitor the temperature of the material 4 to be detected in real time, provide a temperature compensation basis for the accuracy of measurement data, and improve the reliability of measurement.

[0028] Furthermore, a connecting tail pipe 311 is connected to the outer side of the shell 31, and the connecting tail pipe 311 is sleeved on the outer side of the signal line 2.

[0029] Specifically disclosed, the internal component 32 is provided with an electrical adapter 321, and the electrical adapter 321 is located inside the acoustic insulation material 312.

[0030] It should be emphasized that the internal component 32 is provided with a transmitting wafer 322 and a receiving wafer 323. The transmitting wafer 322 and the receiving wafer 323 are located at the junction of the acoustic insulation material 312 and the heat insulation material 313. The transmitting wafer 322 and the receiving wafer 323 are inclined inward at a certain angle. There are two groups of electrical adapters 321, and both groups of electrical adapters 321 are connected to the signal line 2.

[0031] According to the attached Figure 1-2 As shown, it includes a machine body 1, a signal line 2 and a high-temperature probe 3. The high-temperature probe 3 is in contact with the material 4 to be detected. The high-temperature probe 3 is connected to the machine body 1 through the signal line 2. The high-temperature probe 3 includes a shell 31, internal components 32 and a carbon steel pad 33. The internal components 32 are arranged inside the shell 31.

The two groups of electrical adapters 321 respectively transmit the signal to the transmitting wafer 322 and the receiving wafer 323.

[0034] After receiving the signal, the transmitting wafer 322 emits an ultrasonic signal. Since the transmitting wafer 322 and the receiving wafer 323 are inclined inward at a certain angle, the ultrasonic signal is more easily received by the receiving wafer 323 after being reflected by the material to be detected 4.
