NIVELCO measurement system in sponge production (Romania)Instrumentation of Spumotim’ssecond plant in Pitesti, RomaniaSpumotim is an automotivesupplier company manufacturingmultiple kinds ofsponge for car-seats.Moving the production plantcloser to the Romanian carmanufacturer Dacia (a subsidiaryof the French carmakerRenault), Spumotimestablished its second plantin Pitesti. The first plant inTemesvár, built in 2006, wasinstrumented with NIVELCOtransmitters, where they were very satisfied with theNIVELCO products - especially in terms of the productquality and the support service - so they again choseNIVELCO instruments. The shape and the durability ofa sponge are only two from the numerous aspects thatmanufacturers have to take into consideration during thedesign of car-seats. It is essential in terms of comfort andsafety to achieve the proper composition of the compoundingmaterials. That’s why continuous level measurementis needed in the tanks of the raw materials for theproduction process. The instrumentation tasks includelevel measurement, level switching and continuous stockmanagement on 4 polyol and 4 isocyanate tanks.The following instruments were installed:8 pcs. EasyTREK integrated ultrasonic transmitter8 pcs. NIVOSWITCH compact vibrating forklevel switch1 MultiCONT expandable multichannelprocess controller4 pcs. UNICONT PJK universal interface module1 unit of NIVISION process visualization software,with accessoriesThe complexity of theinstrumentation task wasincreased by the requirementto provide accessfor the centralizedstock management ofthe two plants from onecommon control centre.For the level measurementtask, the bestknownEasyTREKintegrated ultrasonictransmitters were chosen,following experience in the plant in Temesvár,because its accuracy and reliability fully meet the requirementsof this measurement task. Measurement signalsare processed by a MultiCONT PR-200 expandablemultichannel process controller. With the help of HARTcommunication the process values are transferred via anRS485/Modbus serial line to the process controller PC.The MultiCONT is also responsible for the high alarmindication which is realized with UNICONT PJK-100universal interface modules. The low-level switching isperformed by NIVOSWITCH RFM-400 compact vibratingfork level switches and the relay outputs of the switchesare connected to an indicator panel.The NIVISION process visualization software receives themeasurement data from the MultiCONT and visualizesthe actual level on the tank-farm. The controller PC inTemesvár and the central management PC are alsoconnected via a remote desktop connection to this PCrunning NIVISION. The complete installation, programmingand configuration tasks for the NIVISION weredone by NIVELCO Romania’s team.András Olteán-PéterFinancial DirectorNIVELCO Tehnica Masurarii SRLaoltean@nivelco.com31
