Acoustic emission instruments
Modules for strain data acquisition equipment Astech Electronics Ltd has added two new modules to the range of over 20 available for the company's DA80 data acquisition system - - a system which typically will handle up to 150 strain gauge inputs and may be used with many types of desk-top microcomputer. The new modules are:
Acoustic emission instruments An alarm system and a leak detector are included in a range of acoustic emission instruments recently introduced by AECL. The units, model numbers 2103 and 2104 respectively, come complete with sensor and low-noise pre-amplifier. The 2100 range also includes three general purpose instruments: the AE Detector (2101) which offers basic signal conditioning and logic facilities; the AE Processor (2102) which offers limited additional digital processing of AE data; and the top-of-range Ultrasonic Stethescope (2105) which is a powerful laboratory instrument suitable for research applications. Prices range from £995 for the 2101 model to £1995 for the 2105.

Hand yokes have improved security and compactness
where it is not always possible to maintain a grip on the yoke to hold the push-button in the 'on' position.

Range of battery chargers for ultrasonic flaw detectors Midland Sonic Services has announced a new range of battery chargers for ultrasonic flaw detectors. The range includes a standard single charger with a constant current output of 0.5 A, a four-way charger designed to charge four Nicad 8-cell batteries simultaneously, and a unique mobile charger which operates from any car cigarette-lighter socket. The last unit can be used with the car stationary or moving and delivers 0.7 A output.

1. A programmable wave form synthesiser which enables the transfer of computer-synthesised wave forms into a buffer memory within a module. These data can then be output as an analogue voltage over a wide range of 'replay' speeds independently of the microcomputer operating system speed. Astech believes that this feature will find many applications in simulation and servo-driving applications for both R & D and production. It enables generation of complex analogue output wave forms and program data using a low-cost microcomputer. As an example, the module could be used in a test/control system in which analogue wave forms could be automatically modified by software until optimum perofrmance of a component or process is achieved. 2. A high-performance reed relay multiplexer offering 16 full differential input channels and complete input isolation when used in conjunction with Astech's 16-bit inte-
A new model has been added to the standard range of Tiede hand yokes for magnetic particle inspection available from Wells Krautkramer Ltd. The BWM 220/12, which was originally developed for the Central Electricity Generating Board, is a compact and powerful yoke similar in construction to the standard BWM type but with a shorter pitch between poles. It differs from most Tiede yokes in that the articulated poles are bolted directly onto the pole ends instead of being clamped. This arrangement is preferred by some users since security is improved and compactness is enhanced. Cable entry has been moved to the top of the yoke to allow a guarded toggle switch to be fitted on that end in place of the push-button inside the 'U' common to other Tiede yokes. This layout is of considerable help in confined spaces
