March 2007: QM Systems delivery proximity switch test solution to Honeywell Control Systems.
Measuring proxmity switches to 10 microns accuracy is not easy - while operating at anywhere between -70 and +130 Degrees is even more difficult. This case study explains the problems that QM faced and how they were overcome in what at first sight looked like a straight forward test system.

Wet arc testing becomes mainstream as Smiths responds to market needs and gathers data to develop protection systems. Safety aspects of cable insulation degradation, wire faults and loose connections are increasingly under scrutiny as the use of aircraft electronics and electrical equipment grows. As a supplier of aircraft electrical power distribution equipment, Smiths is interested in incorporating wire fault detection and arc fault protection systems. With no available standard that could be directly applied to QM's custom built equipment QM engineers considered a whole raft of diverse BS EN standards including those for welding, lab equipment, fume cabinets, emissions from machinery and eye protection. The final safe solution was the result of close collaboration with QM, Mike Bailey at Smiths (in picture) and Smiths H&S team. "I was impressed by QM Systems engineering competence, dedication and willingness to support our pressing deadlines whilst, at the same time, providing a top class unit which will meet all of our safety requirements" Mike Bailey Smiths Aerospace.

QM Systems is pleased to announce the successful development and delivery of an add-on system for the Lockheed Martin LM-STAR® to enable testing of the JSF Electrical Power Management System (EPMS). The system is modular and can be reconfigured to meet other aircraft power requirements.

The QM10000 system was developed for use in development, production and both factory and depot-level support. A key design goal was to ensure the system integrates with LM-STAR®, the mandatory test platform for JSF. QM developed, plug-n-play software drivers make the complete system appear as a single, high-performance instrument to the parent system’s test software despite being a full bay of equipment.

With the capability to source, sink and switch currents of up to 300A and 270V on multiple channels, safety is paramount. Hence a sophisticated safety system, designed with over twenty safety interlocks, provides protection of user and the device-under-test. The system meets the requirements of EN60204 and EN60950 safety standards.

The open system architecture, based upon common off-the-shelf (COTS) instrumentation, offers flexibility to address varying requirements. Where existing COTS did not meet the need, QM has developed innovative hardware and software solutions which are now available separately as individual products, the High Current Multiplexer and the Mains Power Control Unit.
