The relationship of a low acoustic impedance material such as rubber, bonded to steel (high acoustic impedance) produces a radio frequency (RF) signal with a positive-going signal as seen in Image 1 below. When a dis-bond occurs, now rubber has a higher acoustic impedance than air, a 180 degree shift in the RF signal occurs as seen in image 2 and commonly referred to as phase reversal. This technique is well-known in the NDT ultrasonic testing community however, the operator must always be watching the display to find these disbonds. With the latest ECHO software, the operator can now turn on "auto phase detect" on ECHO 7 gages and assign which polarity to arlarm on and the ECHO will change color and vibrate on alarm to alert the user.
Danatronics upcoming software release of Version V2.07 for the ECHO series will allow the operator to create files and turn on the “GridView” feature where you can see, real-time, the live A-scan at the top and the cells within the datalogger file being saved below. The image here shows a red A-scan indicating an alarm has been tripped with the cells all color coded for the previously saved readings. Current users of echo, please go to the support tab and use data xl to upload this new, free software!
Danatronics is pleased to announce ECHO FD; a breakthrough in hand held flaw detection. ECHO FD is an extremely affordable, light weight ultrasonic flaw detector with a bright and fast 60 Hz. display update rate, 2 independent gates, Peak Memory, DAC, AWS, API 5UE, 2 gb memory, B-scan and rubber boot with stand. ECHO FD can switch to corrosion or precision (1 micron resolution) thickness gaging modes.
August 10, 2016 ECHO 7 and ECHO 8 now available!
Danatronics Corporation is pleased announce two new models of our popular ECHO series; the ECHO 7 and ECHO 8. Our brand new ECHO 7 and ECHO 8 series are now available for precision applications. The two new series are available in several configurations to fit your budget and applications. Models are available in basic, Live waveform, datalogger, as well as datalogger with live waveform.
The new models can use contact, delay line and immersion transducers from 1-25 Mhz. with .0001" or .001mm resolution and can store up to 5,000 applications setups. The ECHO 7 series is strictly a precision gage while the ECHO 8 series is our most advanced model using both dual and single element transducers.
