It is possible, to make ultrasonic measurements on line (see: Krautkrämer), but this simple method
doesn´t seem to be very reliable.

It is possible to use for this purpose our holographic method,that we have developed for
fingerprint recognition (see: http://www.optel.com.pl/article/english/article.htm ).
We are interested in developing this method for this purpose, but we need a partner, interesting in financing and/or
using this development.

Using such holographic device, it would be possible to see in real time the contact surface and
the material changes in the neighbourhood.

ISAFE3 Intrinsically Safe Sensor System

ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
...
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.
