Today, level measurement technology is the basis of process measurement and control in the chemical and petrochemical industries, environmental technology and other process-oriented industries. Our comprehensive program enables us to help you solve your particular measurement and control problems and to detect the precise level of any medium, under a wide range of conditions. At Pepperl+Fuchs, level control technology involves the technical realization of all statutory instructions, with the observance of all national (DIN), European (EN) and international (IEC) standards and also involves an active co-operative influence in the formulation of these standards. We also supply devices for use in hazardous areas and for use in water-polluting media, all with the appropriate approvals, e.g. to ATEX 100 or WHG §19. Precise process control, e.g. determination of consumption, loss control, process control and balancing, is possible by continuous level control. Measuring sensors detect the current filling level of the medium at all times. The current level is then transmitted to a secondary control device via a proportional 4 –20 mA current signal,or a digital signal (e.g. via Profibus-PA). Continuous measurements can be made up to Zone 0 in the hazardous area, by choosing the appropriate devices with ATEX 100 approval.
