- N e w equipment Hardness tester inspects poor-quality bolts
M o b i l e X-ray units can be used for fluoroscopy
Sub-standard bolts that break under normal loads can be tested for hardness using an eddy current tester from K. J. Law Engineers of Farmington Hills, MI, USA.
Mobile, constant potential X-ray units for industrial radiography and fluoroscopy have been announced by Gilardoni of Milan, Italy.
The Verimet M1900, as the tester is known, is portable and uses a spot probe or encircling coil to perform random hardness checks. The instrument is claimed to withstand use in hostile environments.
Using a metal-ceramic dual focus and a berylium window tube, the CPX-M160 models, as the units are known, are available in directional or panoramic models. The panoramic unit has an X-ray tube (360 ° x 40 ° ) with a focal spot size of 1 - 3 mm and an inherent filtration of 0.3 mm AI.
Gears, roller bearings and sprockets etc can also be tested
Verimet M1900 is portable

Eddy current unit suitable for tube testing Suitable for high-speed tube inspection, the absolute differential single-frequency eddy current unit from Eddy Current Technology of VA, USA, uses a frequency range of 1.2 kHz to 5 MHz. The unit, known as AD1, features 360 ° phase control, a four digit gain control, with 2000 linear steps, and a continuous balance
mode. Separate horizontal and vertical volts/division switches with five settings control the screen display. The horizontal gain can be controlled to keep the spot on the screen as the probe passes through the skip zones of skip-finned tubing.

Ultrasonic immersion transducer is upgraded Upgraded ultrasonic immersion transducers have been launched by Rolls-Royce MatEval of Warrington, UK, who are aiming to break into the Americandominated European market. With a frequency range of 1 15 MHz and crystal diameters
ranging from 5-25 mm, the transducers are fitted with waterproof UH F connectors in stainless steel cases.

QC system detects dimension changes Changes in component dimensions, which may be rectified before out-of-tolerance limits are reached, can be detected by linking a 2000 series ultrasonic thickness gauge, from Teledictor of Tipton, UK, to a Dataputer 3000 statistical process control (SPC) quality analyser.
Dataputer can provide SPC charts
NDT International October 1988
The Dataputer SPC system, developed by Sellars Datasystems of Manchester, UK, enables thickness gauging data to be interpreted as part of a machine capability study, to predict variations.
CPX-M160 models can be used to test aircraft and ships.

Ultrasonic thickness gauge detects corrosion in steel Corrosion of steel surfaces can be identified using an ultrasonic wall thickness gauge launched by Elcometer Instruments of Manchester, UK. Superceding Elcometer 200, Elcometer 202 is pre-set to measure wall thickness of steel. Calibration controls are not required and readings are automatically displayed in ram. Applications for chemical plant, pipelines and shipbuilding are predicted. The instrument's claimed benefits are its simple specification and easy operation.
