ZD720 Portable Ultrasonic Flaw Detector

圖片41.png

    Rugged ZD720 durability, 8 hours of battery use, easy keys operation, outstanding ultrasonic performance, and now “square wave pulser” and “color leg” combine to form a powerful portable ultrasonic inspection tool with powerful Lithium Ion battery pack.

    The ZD720 combines the powerful advantages of digital design with the detailed dynamic echo information that was previously only possible with an analog display. The high resolution color LCD display, 160 Hz update rate, and “single shot” measurement technique produce a fast, smooth response for immersion and critical weld testing. The quality, durability, dependability and ease of use remains on the BSN80. From rugged field inspections to high resolution thin measurements, long acoustically clean materials, and immersion systems work, the BSN60 extends the range of applications that a portable instrument can perform.

   

 


 

Performance features                                                               

Parameter Setups Files   Up to500 files stored instrument parameter setups.

A-Scan Files         Up to 500files including operation parameters plus A-scan, the stored datasets can be easily previewed, recalled and exported to a computer for edit and printing.

Thickness Files         Up to 10,000 thickness values stored in single thickness file.

PC Communication Bi-directional RS232-USB adaptor connected with PC.

DAC/ TCG DAC or TCG with a maximum of 16 reference echoes, 4 other curves can be displayed with variable dB intervals. DAC curves can be varied with variable dB or variable range.

Readings Up to selectable 26 readings (Sound path, projection distance, depth, echo height, and ERS.)

B-Scan      Selectable corrosion-featured B-scan and full-featured B-scan

Square Wave Pulser Square wave pulsers allow optimum probe matching by adjusting pulse width and voltage. Difficult to penetrate metallic applications and especially non- metals inspection like composite materials are optimized. Pulse width is tunable up to 1000 ns in 10 ns steps. Pulser voltage is adjustable from 20 to 500 V in 10 V steps.

Rectification Positive half-wave, negative half-wave, full-wave, RF

Reject (suppression) 0 to 90% linear

Units Inch, millimeter, or microsecond selectable

Languages Selectable English, Chinese

Gate Monitors Two independent flaw gates controllable over entire sweep range

Measurement Modes Zero-to-first, multi-echo with selectable flank or peak detection

TTL Output Three independently assignable outputs, instantaneous, timed, latched with visual LED and audible horn alarms

Alarm Selectable positive logic, negative logic, upper limit thickness or lower limit thickness alarm mode

Curved surface correction Corrects sound path information when using an angle beam transducer to circumferentially inspect a curved surface for either tubular or bar inspections.

Auto Calibration  Measurement and setting of sound velocity and probe delay using two known calibration echoes (2-point calibration)

Auto Gain Adjust automatically the system sensitivity to bring (increase or decrease) the measured echo to the suitable echo height. Echo height setting value from 10 % to 90 % of the screen height.

Display Screen  5.7 inch LED backlight TFT_LCD, display resolution 320 x 240 pixels, selectable 4 scheme colors and 8 A Scan colors.

A-Scan Resolution    Standard 200 x 220 pixels, or 100 x 220 pixels
