Can anybody help me in finding literature (Practical tips and fundamental info) about this subject? : Thanks, : Jack Tensen ------------------------ It will be difficult to find literature of squirter design since this is an essential know-how of the system suppliers. That's why so far we haven't received many answers in this forum. With my little experience in this subject I will try to give some hints. 1. Precondition is an air bubble-free water supply with appropriate pressure accordingly to the length of the water jet you want to drive. 2. I guess that you mean by "small ultrasound squirter" the length of the water jet. The free jet can reach a length of about one meter. Applied with a short length it is called a bubbler (a few centimeter) In the UT encyclopedia is written about it together with a principle picture. www.ndt.net/article/az/ut/wat.htm 3. Small turbulences can appear, the signal to noise ratio is often less than in the immersion technique, that is the challenge of the design. The squirter housing should consider the evacuation of possible air. It is important to test the squirter in different positions, often the vertical position brings air problems. Air tries to get up and can accumulate in the housing. It is a also sometimes a question of operation time until it begins to fail. Increasing pressure can help, but keep the jet laminar. I hope that this can help you a little bit.

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. > 2 Showcases more Showcases
