Automatical Time Varied Gain

Dear Sirs,

Our company is looking a Ultrasonic Flaw Detector with automatical Time Varied Gain. Could anybody advise us products that have such feature. I will really appreciate your help.

I am not familiar with "time varied gain", but if it means the ability to for the machine to automatically compensate for attenuation by increasing gain with distance, or time interval, many, if not most, flaw detectors have this feature. In the US, it is called "distance-amplitude correction" or DAC.

Dear Mr. Woodward,
Thank you for prompt answer. In my question I mean the ability to automatically calculate DAC for material under test. As far as I know most of flaw detectors use for correction stored setups.

Dear Sirs,

If the flaw detector uses digital signal processing, it is possible to add such a function.
We can - for example - make it easily in our OPKUD device (see: http://www.optel.com.pl/manual/english/osc2.htm)

Sincerely

Wieslaw Bicz (Optel http://www.optel.com.pl)
