The objective of the development was to develop new sensors acts to fully respond to new technical requirements of the market in accordance with the harmonized standards. The innovative aspects of the research are concentrated in the adoption of primary transduction elements, extremely efficient and robust, suitable for the new operating conditions imposed by the rules. Sensor Systems Srl, in constant collaboration with national and international research institutes, therefore was able to achieve the objectives imposed by the new EN ISO 13849-1.
The European standards EN 280 and EN 954-1, EN 18349 governing the design, the construction and the safety of machine delegated to lift of work platforms, construction equipment and cranes have now given way to a new concept of "machine" which requires compliance with rigorous safety limits both active and passive. In particular, the EN ISO 13849-1 , following EN 954-1, it becomes the central norm to the lead of the security systems in the " Safety of machinery" and its harmonization under the Machinery Directive is scheduled for the end of the 2009. One of the main innovations of the standard is the probabilistic approach in relation to the evaluation of control systems security. The reworking of the standard EN 954-1 is designed to give a probabilistic footprint required in the evaluation of modern control systems. The decisive step in this regard was to use the general categories are already well known and at the same time considering further quantitative characteristics relevant in terms of safety. In particular, an important role in the categories is the use of sensors of new concept compared to traditional approaches used to date. Sensor Systems Srl , based on this new concept of security has concentrated its efforts in technological research and development of innovative sensors and systems suitable to meet the new requirements imposed by the harmonized standards. In particular, Sensor Systems Srl has focused on the study of inclinometers in micro-machined silicon technology (also known as Micro Electro Mechanical Systems MEMS) with CanBus digital communication interface, and rotary sensors for non-contact Hall effect CMOS technology.
