High Precision Digital Ultrasonic Flaw Detector for Small and Thin Pipe Inspection

Digital Ultrasonic Flaw Detector has the features of quick and non-destructive testing, high precision and easy to carry. It can test,locate,assess and diagnose a variety of detects within the work piece such as crack, weld, porosity, blister, inclusion and folding.

Digital Ultrasonic Flaw Detector is widely used in electric power, petrochemical industry, boilers and pressure vessel, steel structure, military industry, aerospace, rail transport automobile, machinery and other fields. It is a requisite equipment in nondestructive testing industry.

Main function: 

High precision positioning and quantifying meets the requirements of close and remote detection;

Small near-field blind area meets the requirement of small diameter and thin wall pipe detection;

Automatic calibration: “one key” automatic calibration is very convenient. Automatically test “zero point” “K value” and “frontier” of the prob as well as “sound velocity” of the material;

Automatically display the defect echo position ( depth-d, horizon-p, distance-s, amplitude, equivalent-dB, aperture value);

Switch the three scales (depth-d, horizon-p, distance-s) freely;

Automatic gain, echo envelop and peak memory function improve the detection efficiency.

Automatically record testing process and available for dynamic playback;

Φ calculation: straight prob forging flaw detection, find the summit detection wave to convert Φ value;

100 independent inspection channels (extensible), are free to enter and store any industry standard of inspection. test block is not necessary;

Store and playback 500 groups of A sweep wave forms and data;

DAC, AVG, TCG curves (compensation) can generate automatically and sectional manufacturing. Sample point is not restricted and can be revised and compensated;

14 built-in detection standard can be assaulted;

Free to enter any industry standard;

Emission pulse width and intensity is adjustable;

B scan function, clearly display deflect longitudinal section shape;

Communicate with computer, realize computer data management and can export Excel format and A4 paper detection report;

IP65 standard aluminum magnesium alloy shell is durable, waterproof, dust-proof and anti-jamming;

PC communication software can be used to upgrade the function of instrument system;

260,000 color screen display, brightness is adjustable and suitable for strong and weak light work environment;

High performance security environmental friendly lithium batteries can work continuously for 8-10 hours;
Real time clock record: record and store real time detection date, time;

Power off protection, storage data will not lost;

Detection parameters can be automatically tested and preset;

Digital rejection, the gain and linear will not be affected;

Gain compensation: Db attenuation caused by surface roughness, curve, thick workpiece detecting at a long distance and other factors can be revised;

PC communication software keyboard operation, achieve the goal of computer controlling equipment main body when detecting;
 

Important auxiliary function

Angle and K value-- two kinds of input methods;
Echo frequency analysis;
Power state indication;
Gate audible and visual alarm;
DAC sound and light alarm;
Screen freeze and thaw
Clock display;
Dormancy and screen protection;
