Measurement principle

The emitter in the sensor is excited electrically and sends an ultrasonic pulse in the direction of the surface of the material which then partially reflects the pulse. This echo is detected by the same sensor,now acting as a directional microphone,and then converted back into an electrical signal.The time between transmission and reception of the pulse(the sonic run time) is directly proportional to the distance between the sensor and the product surface. This distance is determined by the velocity of sound c and the run time t using the formula:

D=c*t/2

For example,if sound c is 344.1m/s(@20 Deg.C and 1 atmospheric pressure),run time t is 50ms and then distance is 8.6m.

Ultrasonic toothbrush also by the electric drive, thus belong to electric toothbrush, namely ultrasonic electric toothbrush. But in many non-standard sales promotion, “electric toothbrush” is a single refers to “rotary electric toothbrush”. Rotary electric toothbrush bristles are arranged in the round, the use of rotating brush a head for contact friction clean, manual and brushing your teeth basically the same effect. And the head of sound waves toothbrush brush in appearance and manual tooth brush head completely, is through the high frequency vibration to undertake cleanness. But some special toothbrush used the combination two brush head (vibration and the rotating) way, we need to look at specific instructions to determine the types.

Ultrasonic toothbrush should refers to the frequency more than human hearing cap, namely 20000 hz. And many of the vibration frequency hundreds of Hertz only ordinary sound waves have also been some sellers toothbrush publicity for the ultrasonic toothbrush caused consumer confusion, in fact, those who “ultrasonic” toothbrush is the “voice sound waves”, that is to speak more than human when talking to the hundreds of Hertz acoustic frequency, have the suspicion of concept sameness. Voice of human language itself is defined frequency fuzzy, even use “super voice sound waves” standard would be difficult to confirm. And this kind of frequency difference between toothbrush is not big, there is no need to another division “super voice sound waves toothbrush” this classification.

Ultrasonic thickness gauge adopts the latest micro-process technology with low power consumption and high performance.Based on the pinciple of ultrasonic,ultrasonic thickness gauge can measure wall thickness and sound velocity of various kinds of metal and other material.Can measure pipes and tanks to check the corrosion situation.Ultrasonic thickness gauge are widely used in Petroleum, chemical industry, metallurgy, shipbuilding, aviation and aerospace,and other industries.

Ultrasonic thickness gauge is mainly comprised of three pars:main unit,probe, and cable. Ultrasonic thickness gauge is usually powered by batteries.

Using skills

1.general measurement method

1)Test 2 times on one point.In the two tests, the parting plate should be 90 Deg. with each other, and use the smaller value as the test value

2)30mm multi-point test.When the test value is not stable,take an test point as a center,test many times at the diameeter of 300mm,and take the smaller value as the test value.

2.Line measurement

Use single point measurement on the designated routes and the distance of two point is not over 5mm

3.Gridding measurement

Cross grid on designated area,and measure the designated points.The method has been widely used for corrosive test on high pressure equipment and stainless steel lining.
