Calibration and Measurement

Application of DAC Cure

DAC curve is used for distinguishing the reflectors with the same size and different distance. Normally, in work piece, reflectors with the same size and different distance cause change in amplitude because of the attenuation of material and pervasion of beam. The DAC curve compensate for attenuation of material, magnetic field influence, pervasion of beam and surface smoothness in the way of graph. Normally, the echo peak points are all located in the same DAC curve. And in the same way, the echo created by smaller reflectors will be located under this DAC curve, and the bigger one will be above the curve.

Selection of detecting setting. Select the setting function group by the key <Setting>, adjust the detecting setting number, choose one as the current instrument setting, for example, No.1, ( Note: One group of DAC plotting points can be saved in one setting, and they are saved automatically, not needing any operation, if you want to save the parameter setting at the same time, turn to the operation “SAVE”.
Turning on DAC curve function. Select the DAC1 function group through shortcut key, and then select the DAC curve function through up/down keys, (if the DAC curve function doesn’t lie in the current menu, please switch it by the <Enter> , plot the revision function), set the DAC curve switch By the rotary knob.
Making DAC curve. Select the DAC1 function group through shortcut key, Add plotting points according to 3.7.2, when two plotting points are finished, the DAC curve will be protracted automatically. (Note: Plot the points in the order of small to large according to the detecting range, and the echo height of latter one must not be higher than the fore one, otherwise, the DAC curve will be a beeline.)
Adjust the offset of the three offset curves. Select the DAC2 function group, adjust the three offset curves viz. DAC-EL, DAC-SL and DAC-RL to proper settings.
The completed DAC curve:

The screen is divided into three areas, Ⅰ, Ⅱ and Ⅲ. The three curves will be drawn on the screen during the detecting, users can determine the flaw character by the height of the echoes

Contents of Measurement

To use the detector for measuring, you shall carry out the following works:

Set the start of gate, gate width, gate threshold and gate alarming way.

Contents of measurement are:

S Pitch interval
H(%) Relative value of echo height in gate range (relative to the screen height)
h Absolute value (in pixel) of echo height in gate range
d Depth of defect
D(%) Relative value of defect depth (relative to job’s thickness)
P Horizontal distance of the defect from the probe’s front edge

As for the meanings of above parameters, please refer to the following figure.

Where:

s: Pitch interval;
d： Depth of defect;
t: Thickness of job;
x: Distance of ultrasonic source to the probe’s front edge;
p: Horizontal distance of the defect from the probe’s front edge;
D: Is the relative value of defect depth, it is obtained by the following formula:

Matters needing attention before measuring:

The calibration including sound speed and P delay shall be completed, and the measuring way can be selected as front-edge and peak way. The wave amplitude measured is the max. echo amplitude within the gate. With front-edge measuring way, the pitch interval measured is the pitch interval at front edge of echo within gate (up line of echo waveform curve).Therefore, when front-edge way is selected, the measurement on echo amplitude in the gate is influenced by the gate threshold (height). The measurement of pitch interval can be done only when the gate is open, before measuring, you should select the measuring way: edge way and peak way. Then select single or double gate way. Under single-gate way, the measurement is the pitch interval at echo’s front edge or peak in the gate. Under double-gate way, the measurement is the pitch interval starting from the echo within gate A and ending at the echo in the gate B.

Type A display: a kind of way for expressing information where horizontal base (X axis) is used for expressing distance or time, and the deflection which is vertical to the base (Y axis) is used to express the amplitude.
Sending pulse: electric pulse added to the energy exchanger for producing ultrasonic wave.
Time-base line: horizontal scan line expressing time or distance in type A display fluorescent screen.
Scan: the repeated movement of the same style from electronic beams that runs cross the detector’s fluorescent screen.
Scan range: Max. pitch interval that can be displayed on the time base line of the fluorescent screen.
Scan speed: ratio of cross axis to corresponding pitch interval on the fluorescent screen.
Delayed scan: a kind of scanning way where the starting part of the time base will not show in type A or B display.
Horizontal linearity: the extent for the signal displayed on the time or distance axis of the ultrasonic detector’s fluorescent screen to be proportional to the signal entered into the receiver (multiple echoes from the calibrated time generator or from a plate whose thickness is known).
Vertical linearity: the extent for the signal displayed on the time or distance axis of the ultrasonic detector’s fluorescent screen to be proportional to the amplitude of signal entered into the receiver.
Dynamic range: with constant gain adjustment, ratio of wave height of the max. to the min. reflection area that can be identified on the ultrasonic detector fluorescent screen. It is normally expressed by dB.
Repeating frequency of pulse: no. of pulses the pulse generator uses for exciting the probe’s wafer per second to generate the ultrasonic wave.
Inspection frequency: frequency of ultrasonic wave used during ultrasonic inspection. Normally it is 0.4 MHz ~15MHz.
Frequency of echo: inverse of time of peak interval obtained by observing when the echo extends on the time axis.
Sensitivity: a kind of dimension for the min. ultrasonic signal identifiable that is generated on the ultrasonic detector’s fluorescent screen.
Allowance of sensitivity: difference between the standard and max. defect-detecting sensitivity in term of certain electric level in an ultrasonic detection system.
Resolution: capability of an ultrasonic detecting system for extinguishing two adjacent defects of certain size that are most close to each other in transverse, longitudinal or depth direction.
Suppress: a kind of controlling way to reduce or remove signal of low amplitude (electric noise or noise from material) so as to highlight the high signal in an ultrasonic detector.
Gate: An electronic method for selecting a time range for monitoring the detecting signal or for further processing.
Attenuator: a unit changing quantitatively the signal voltage (sound voltage). The attenuated volume is expressed by dB.
S/N ratio: ratio of ultrasonic signal’s amplitude to the max. background noise’s amplitude. It is normally expressed by dB.
Blockage: a phenomenon occurred in the moment after the receiver receives the sending pulse or strong pulse signal where its sensitivity drops or it fails.
Gain: the log form of voltage amplification of the receiving amplifier of the ultrasonic detector. It is expressed by dB.
Distance-amplitude curve (DAC): a set of curve plotted according to specified condition by three parameters, i.e. distance of the known reflector, gain of the detector and size of the reflector that generates echo. During the actual detection, one can estimate the equivalent size of defect from this curve based on the measured defect distance and gain.
Coupling: action that transmits acoustic wave between the probe and the inspected part.
Test block: a sample for determining the features and the detecting sensitivity of an ultrasonic detection system.
Standard test block: a test block whose material, shape and size are calibrated by a body in charge or authoritative institute. It is used for testing the performance and adjusting sensitivity of an ultrasonic detection unit or system.
Comparing test block: the test block used for adjusting the sensitivity of an ultrasonic detection system or comparing the defect. Generally, it is made of the material similar with the material to be detected.
Probe: electric sound converting component for sending or receiving (or both) ultrasonic energy. This kind of device normally consists of trademark, plug, casing, back lining, piezoelectric component, protective film or wedge.
Straight probe: a probe for vertical flaw detection, which is mainly for detecting longitudinal wave.
Angle probe: a probe for angle-sending flaw detection, which is mainly for detecting transversal wave.

Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose. In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law. For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.\ If you have any questions, please contact PCE Instruments.
