a&B Scan Thickness Gauges

Features of UE0073:

1 Live Color A-Scan

The user can directly see the A-scan wave form on the screen, which is quite important for the situation that we need to validate the testing results. Many causes will cause incorrect testing results or even no testing result. We could find the causes easily through the A-scan. And adjust the GAIN, BLACKING and GATE three parameters to get the correct testing result.

2 Live Color B-Scan

A B-scan is a cross-sectional image of thickness value. The UE0073 can acquire and display live B-scan data. It is used to check the bottom outline of testing part; The instrument will automatically catch the Minimum value of the whole B-scan image. When user moves the point line on the B-scan image, the UE0073 will display the thickness value of each point of B-scan image.

3 Adjustable GAIN

User can increase or decrease the amplification factor of echo signal, by 1 dB step. It is quite useful for acoustic attenuation materials (e. G. Cast iron) testing.

4 Blanking function

The UE0073 ultrasonic thickness gauge use blanking function to invalidate the noise wave before the first underside wave, like below picture, instrument will invalidate the waves above the red line, and omit the useless noise waves that impact the measured thickness value, it's useful in testing of rough surface or nonuniform inner structure part.

5 Adjustable GATE

The UE0073 ultrasonic thickness gauge only get the thickness value when the wave is higher than the gate. So the adjustable height of gate is very important, especially in low echo signals testing (e. G. Ultra thin sheet, ultra thick plate).

6 Red arrow

When measure the thickness value, A red arrow will point to a point of A-scan waveform, that indicate thickness value of the waveform point. It will help user to validate the measured thickness gauge. We will get the correct thickness value when the red arrow point at the advancing front of the first underside echo.

7 Rectification modes
Four modes selectable: RF, Half-Wave Positive, Half-Wave Negative and Full Wave.
RF: Describe the whole echo waveform.
Half-Wave Positive: Show the Half-Wave Positive without the Half-Wave Negative.
Half-Wave Negative: Upturn the Half-Wave Negative and dispose of the Half-Wave Positive.
Full Wave: Show both the Half-Wave Positive and upturned Half-Wave Negative.

8 High resolution OLED screen

The UE0073 ultrasonic thickness gauge use 2.4" color OLED screen, it can be clearly display under high-light and dark situation, the contrast of the OLED screen is 10000: 1, it's 40 times of TFT screen, the resolution of this screen is 320 * 240 pixels, it's 9 times of competitor's products.

9 Past Zero Detection Technology
UE0073 ultrasonic thickness gauge is total digital ultrasonic thickness gauge, all the Live A-scan function, past zero detection technology and high-precision are base on the digital signal; By using the Past Zero Detection Technology, the UE0073 testing value is not affected by the echo intensity, material attenuation coefficient, gain and gate height, so the testing data has higher reliability.

10 Real 0.01mm resolution
UE0073 ultrasonic thickness gauge has real 0.01mm resolution, usually, the resolution of normal ultrasonic thickness gauge is called 0.01mm, but it's real resolution can't reach 0.01mm, because it's timer counter of hardware is usually below 30MHz, and the hardware resolution can reach 0.1mm, by average many testing data, it generated a 0.01mm resolution testing data, this can not effectively improve the real resolution, but it will cased unstable testing result. The UE0073 using advanced digital technology and special algorithm, it has real 0.01 mm resolution, the experiments show that it can easily distinguish two test blocks that the thickness difference is only 0.01mm.
