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)

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
