Abstract
In this paper we present the results of implementation of a remote control system based on ProFiBus technologies used for the remote control of experimental nuclear physics apparata. Remote control makes experiment handling more flexible, eliminating any problems originating from the need for direct access to the systems being controlled. In the paper we describe two different applications. The first application of the ProFiBus is the remote control of a multidetector (made up of a bidimensional array of CsI scintillators) used to detect light nuclear particles, as protons and/or light ions. In the second application, we present an implementation of the control of a vacuum system suitable for a special chamber used for the development and testing of particle detectors operating in vacuum conditions.

A real time instrumentation approach for bridges and tunnelsDerya Dinçer
Among all civil engineering structures, bridges & tunnels are two of the leading types that should be monitored by sensors due to their critical fatigue and creep behavior. Especially natural events such as earthquakes, floods, storms increase the importance of monitoring. A number of different types of instruments and sensors should be combined in health monitoring of railway/highway bridges, tunnels, tube crossings and subways. Although customization has a big importance in a specific health monitoring instrumentation project of a bridge or tunnel, accelerometers, strain/crack gauges, tilt, wind and temperature sensors are the most generally preferred sensors.

For diagnosis, to:
• Prove structural fitness for purpose
• Check novel systems of construction/structural forms
• Validate structural modifications & mitigation measures
• Track structural loads/overloads/extreme responses
• Evaluate ’servicability’ –e.g. user comfort/safety
• Provide a feedback loop to design and loading codes
For prognosis
• Assess structural safety after trauma (e.g. earthquake/impact/bridge scour)
• Track long term degradation to aid maintenance decisions
• Detect ’damage’? –In rare cases outside lab and simulation: please tell me!

Paut based techniques developed for power industries and refinery in taiwan ...Yung how Wu
Although conventional ultrasonic method is still widely used elsewhere, PAUT technique is applied increasingly for improving the ISI of utility, refinery and as well the emerging wind power in Taiwan. PAUT together with scanner is one of the major advantages to precede conventional UT by enhancing the defect characterization or inspection speed. In this study, special scanners were designed and employed with PAUT for the inspection of composite blades, bolts of wind turbine and anchor bolts of nuclear RPV skirt. Results showed that delamination of composite and fatigue crack of bolt may be detected and sized in more confidence and convenience for in-situ inspections. Moreover, PAUT was also used to characterize carefully the inner crack of pressure vessel for FFS assessment. Crack was found in safe margin and hence remained to operate. In conclusions, PAUT together with manipulator designed for specific purpose may facilitate the applications of PAUT technique widely in ISI of various industrial sectors.
While research and development of Electro-Magnetic Acoustic Transducer (EMAT) technology has been active for several decades, hardened production inspection system applications remain limited. Applications remain limited despite the several and distinct advantages and EMAT probe can have over conventional piezoelectric ultrasonic devices.
In addition to being comparable in ultrasonic wave mode generation and sensitivity, under proper design, an EMAT probe offers the following advantages for the production minded engineer: (1) no fluid couplant is required, (2) the test can be non-contact, (3) works on rough, dirty, and hot surfaces, (4) can be operated at very high scan rates, (5) easy to automate, and (6) capable of generating useful waves modes that are difficult to generate with piezoelectric devices. Basic elements of an EMAT system are explained and a comparison to conventional piezoelectric devices is made. By using real application cases, the benefits of EMATs are demonstrated. These real cases include: (1) flash butt-weld inspection, (2) mill roll inspection, (3) automotive laser weld inspection, and (4) tube & pipe inspection.

Non destructive test systems are increasingly applied in the industrial context for their strong potentialities in improving and standardizing quality control. Especially in the intermediate manufacturing stages, early detection of defects on semi-finished products allow their direction towards later production processes according to their quality, with consequent considerable savings in time, energy, materials and work. However, the raw data coming from non destructive test systems are not always immediately suitable for sophisticated defect detection algorithms, due to noise and disturbances which are unavoidable, especially in harsh operating conditions, such as the ones which are typical of the steelmaking cycle. The paper describes some pre-processing operations which are required in order to exploit the data coming from a non destructive test system. Such a system is based on the joint exploitation of Laser and Electro-Magnetic Acoustic Transducer technologies and is applied to the detection of surface and sub-surface cracks in cold and hot steel slabs.

The RA802 Pharmaceutical Analyser combines Renishaw's proprietary LiveTrackTM and StreamLineTM technologies to generate chemical images up to 150 times faster than conventional methods, whilst maintaining focus ? ensuring high quality pharmaceutical tablet imaging.
While an EMAT (Electro Magnetic Acoustic Transducer) in its simplest form is comprised of a magnet and an RF coil used to generate sound by electromagnetic induction in materials it is actually a rather complex system where each part of the sensor and instrumentation needs careful optimization for application specific performance. Historically EMAT inspection has suffered in widespread use because of a fundamental problem with the technology which is transducer inefficiency. EMAT requires very high power and very precise electronic designs to generate and
detect the signals.

The Avermetrics test system is faster for production testing, and even more so when testing multiple channels, since the system is built to test all channels simultaneously, instead of only one or two channels at a time.
The following endorsement was made by a well-known contract manufacturer who currently uses the Prism and AP Testers:
“We are using in our Manufacturing line the AVERMETRICS Test & Measurement System in our Pro-Audio production lines to test our products since Nov, 2014. Last year and again recently, we studied the performance of the production lines using AVERMETRICS testers, compared it to the previous test methods which we had used, before we installed your modular testers. We have realized that the test time needed is much less now, in some cases coming down by a factor of 5 or more, and the AVERMETRICS Tester also creates very stable results. We are looking forward to another meeting with you so that we can discuss using your newly announced modules and even more AVERMETRICS test systems for our other production lines. Thanks for your great support!”
AVERMETRICS is currently also designing and developing additional test modules, such as Digital Multimeter Modules, etc.
You can download the Product Brochure from the AVERMETRICS Web Site.
