What is the detection range of the ultrasonic thickness gauge probe? Zunxiang Technology's ultrasonic thickness gauge uses the pulse reflection of ultrasonic waves in the medium to measure the thickness of an object, which is called ultrasonic thickness measurement. The ultrasonic thickness gauge mainly consists of two parts: a host computer and a probe. . So, what is the detection range of the ultrasonic thickness gauge probe? In this regard, Zunxiang Technology will introduce it to you.
What is the detection range of the ultrasonic thickness gauge probe? The detection range of the ultrasonic thickness gauge is introduced by Zun Xiang as follows:
The ultrasonic thickness gauge measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe reaches the material interface through the object to be measured, the pulse is reflected back to the probe and the measured time is determined by measuring the propagation time of the ultrasonic wave in the material. The thickness of the material. This principle can be used to measure various materials that can allow ultrasonic waves to propagate inside them at a constant speed.
The thickness gauge designed based on the principle of ultrasonic pulse reflection can measure various plates and various processed parts. It can also monitor various pipes and pressure vessels in production equipment and monitor their thinning after corrosion during use. degree. It can be widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields.
Calibration method of galvanized layer thickness gauge
1. Press and hold the power button until "CAL" appears on the display (this process takes about 4 seconds). The display will display "F:H". At this time, lightly press the zero calibration button to confirm (the probe must be suspended)
2. Press and hold the power button until "Ln" appears on the display (this process takes about 9 seconds). The display will display the number "0.8XX". If the data is found to be too large during the test, that is to say, 127um is correct, and The diaphragm of about 420um is too large. You can increase the number (use the "+" key), or decrease the number (use the "-" key). Approximately every time the number increases by 0.001, the number around 420um will decrease accordingly. 2um. Then press the zero calibration button to confirm. (The probe must be suspended)
3. Regardless of whether the first step or the second step is completed, the zero should be reset after the operation is completed.
Pay attention to the method of the sensor plug. After turning on the machine, press the probe onto the iron base and lightly press the zero calibration button. Place the standard diaphragm (about 127um) on the iron base. If the measurement result is not around 127um, it can be adjusted through the plus and minus keys. After adjusting the diaphragm around 127um, measure the diaphragms around 52um and 420um respectively to see if they are within the allowable error range. If it is found that all diaphragm values are basically correct, the calibration is successful.
