20 picture NEWS AND MARKETS HARD- AND SOFTWARE PROVIDE SAFETY Safety is extremely important in the world of mobile machinery. This relates to the safety of the control, drive and working process. To guarantee this safety, electronic control units within the hardware and software must be prepared, designed and qualified accordingly. This sets the highest requirements for the development process, qualification, documentation and production. The ESX-3xx range with 32-bit processors is designed for these requirements and certified for use up to performance level PL d and safety integrity level SIL 2. Sensor- Technik Wiedemann develops hard- and software, produces the control units at its own production facilities, and supports customers to develop applications in accordance with the V-model. www.sensor-technik.de/en MDA Technologies 4/2016

30 MACHINE ELEMENTS CLASSIFICATION ACCORDING TO DIN 51524 The requirements of hydraulic fluids on mineral oils basis are regulated in Germany by DIN 51524. Amongst other things we distinguish between HL, HLP, HVLP and HLPD. HL stands for hydraulic oils with active substances to increase corrosion protection and durability, which can be used up to 200 bar. HLP stands for hydraulic oils (pressurized fluids); hydraulic oil that provides increased wear protection: DIN 51524, Part 2 HLP: like HL, however with high pressure additives, also for pressures above 200 bar. HVLP oils in addition have improved viscosity. HLPD mineral oils in comparison to HLP oils offer additional detergent properties. ASSESSING FLUIDS DEVELOPMENTS OVER THE LAST FEW YEARS The demands and efficiency in hydraulics have increased significantly. The power to weight ratio of axial piston pumps and motors for example has more than doubled over the last few decades. Over and above this the level of pressure in numerous applications has risen considerably. This improved performance places demands on the hydraulic fluids used much more than before. Hydraulic fluids in combination with the operating conditions have a decisive influence on wear behavior and in this way on the life expectancy of hydraulic components. STANDARDS ARE NO LONGER UP-TO-DATE The minimum requirements valid to-day in the corresponding DIN 51524 standards for hydraulic fluids based on mineral oil, ISO 15380 for environmentally compatible hydraulic fluids as well as ISO 12922 for hydraulic fluids with low flammability, do not however reflect these increased demands. Up until now however mechanical equipment manufacturers have only been able to rely on fluid manufacturer details when choosing their fluids, and chose suitable fluids by trial & error. One mistake here threatened to shut down the machinery and bring high warranty claims. MDA Technologies 4/2016
