Position transducers keep on performing while James Bond is shaken and stirred

EMP Designs is a leading Industrial design consultancy and systems integrator specialising in motion control and automation projects. One of EMP's major market areas is film motion control, supplying complete motion base positioning and control systems for blockbusters like the latest James Bond movie, Casino Royale. With the high cost of delay and the complex schedules involved in the film industry, EMP Designs regularly chooses Variohm Eurosensor for linear position and cable-extension transducers.

In a typical filmed scene, several hydraulically actuated motion bases may be synchronised with CGI and movie cameras for carefully choreographed stunts and action sequences which involve precise positioning of heavy objects or even large structures that sink. Positional feedback for the model platform was provided by six Variohm PT8420 cable-extension position transducers which have a high pedigree for use in harsh environments.

The IP68 rated PT8420 housings were mounted in the water below the motion base with stainless steel extension cables connected to the moving part of the submerged hydraulic cylinders. This cost effective and compact solution was simple to install and set-up with no need for precision alignment.

In another application, EMP produced a 3-axis control system to provide 'pick up and use' usability, where a scaled replica model of the motion base and a simple 3-button control console are used to input, record and playback complex move sequences.
