Design and manufacture of a force/displacement measurement test rig for a range of automotive brake calipers. The loadcell and displacement transducer signals were amplified prior to data collection by an industrial PC. Data was displayed on a pan/tilt TFT screen. The system was controlled by a purpose designed Logic Control PCB driving a geared motor. The whole test rig was mounted as 19" racking on a modular aluminium frame.

Design and manufacture of pressure test equipment for a variety of brake caliper bodies. Shop air at 5.5 bar and 170 bar (via a 30:1 rig intensifier) was used for leak tests, low pressure tests and high pressure tests. Each test type was individually selected and automatically controlled using a PLC. Data was output from various flow-meters and pressure transducers and compared to acceptable values in the PLC. All pressure testing was undertaken in a containment box, in case of component failure, with the appropriate safety interlocks.

Design and manufacture of an Aircraft Battery Charger Tester, incorporating a means of varying 115V, 400Hz, 3 phase supply between zero and 140V output. This was based around a 19" rack system and consisted of a control/status monitoring chassis and a battery transformer chassis, each being usable as a separate unit. Aircraft power conditions were simulated and selected from the front panel, and power in each phase is displayed on a programmable digital display.
