-New equipment Eddy current system incorporates robot A seven axis programmable robot has been incorporated into an automatic eddy current system from Staveley NDT Technologies of Slough, UK, which will be used to examine bolt holes and bead seat areas of Airbus wheels. In Staveley's first venture into the automation of low-end routine testing, the robot, known as RTX, will manipulate probes and transducers to accurate locations of components. The aim is improved repeatability of test results which, until now, were carried out manually, resulting in an inconsistent standard of reproducability. The rotation head of the RTX holds a rotary eddy current probe and presents it to each bolt hole in the wheel as programmed. Automatic changeover of different

probes to suit the hole size and bead-seat configuration of any diameter wheel is possible. A permanent record of the test results can be recorded on a greyscale printer for immediate assessment and then filed for comparison at the next scheduled overhaul. For other applications, the robot can be used with an ultrasonic instrument.

Aiming to move into a previously unexploited area of routine testing automation, Staveley will be marketing the RTX as an expansion of their existing product range. New market opportunities are anticipated and a new set of industry repeatability standards is expected. The manufacturers of RTX, Universal Machine Intelligence of Surbiton, UK, are keen to hear

Infrared system to be used for maintenance

Robot-based control systems for use in automated inspections have been designed by Technatom of Madrid, Spain.

Predictive maintenance is the market being aimed at by Agema Infrared Systems for its Thermovision 450 infrared thermal measurement system.

The Siroco systems have been designed to allow the control of any type of mechanized equipment, manipulator a n d / o r robot used for inspection and maintenance tasks. Two models have been designed, one with six simultaneous movement control units and one with three. The first six-unit systems to be built will be used with BWR reactor vessel ultrasonic inspection equipment, while three-unit systems are to be used for the ultrasonic inspection of steam generator tubes, reactor vessel and steam generator nozzles and reactor vessel closure head studs. Technatom forsees the construction of another sixunit system this year for use in turbine disk and PWR vessel inspections.

The portable system uses a pointand-shoot system to avoid excessive training requirements. It is said to be usable from moving vehicles and in damp conditions.

Thermoelectric cooling is used. The Thermovision 450 can be linked to a standard video recorder. It measures temperatures over the range - 20'~C to 1500' C in ambient temperatures of -15 Cto55'C.
