Products - MALMS Workshop Tester / Photometric Bench

The MALMS product range also includes two systems specifically designed to provide fast, repeatable and semi-automatic methods for testing the performance of individual AGL fittings in a workshop, factory or laboratory. The MALMS Workshop is designed to test fittings following refurbishment. The system is compact and self-contained such that it can be easily located in the workshop. Whilst the MALMS Photometric Bench is an enhanced testing unit which measures photometric performance (Average Intensity in the Main Beam area) by the method specified by ICAO Annex14 and provides the facility to store and review results.

The core system, common to both the Workshop and Photometric Bench, incorporates a driven, bench mounting turntable unit, position sensors, control panel and a light sensor array (standard and advanced) that comprises of high accuracy light sensors, which include photopic response filters. These sensors are calibrated on a photometric bench against a NPL [UK National Physical Laboratory] photometer.   For ease of use, both systems are controlled by a specifically developed, PC based, software package. This software enables the user to select a pre-defined test from a list. The programme for this test includes beam specification and pass / fail criteria. The computer will then run this test sequence automatically, once the turntable access door is closed. On completion the system displays the results on screen, for both side A and B, and covering Average Main Beam Intensity (Cd), Vertical Beam Alignment error (Elevation), Horizontal Beam Alignment error (Azimuth). The software also provides functionality to enable the system administrator or operator to calibrate the system, to take manual control of the turntable and laser, to define new tests or modify existing test criteria. Additional data storage, analysis and reporting functionality is provided by the MALMS Luminaire Database (optional for the Workshop).
