The further improved high purity aluminium oxide ceramic diaphragm Certec measuring cell is used in the new Vegabar 40–44 Series. The instruments are the optimum solution for pressure measurement of virtually any products in the paper, chemical, food processing, pharmaceutical and water/wastewater industry.
Industry-specific and other various process fittings and materials from stainless steel 1.4571 up to PVDF enable comprehensive process adaptations. The housing in protection IP65 consists of high resistance, shock-proof plastic or powder-coated Alu-die casting. This makes Vegabar suitable for use in aggressive environments or under extreme mechanical loads, as well as in EEx d applications.
The design of these process pressure transmitters permits easy removal for repair, without having to empty the vessel. This quick change of transmitter eliminates the costs once associated with setting up the replacement instrument.
Parameter adjustment of the Vegabar Series can be done locally or from the control room via a laptop. The integrated menu-guided adjustment offers many useful features such as unpressurised adjustment in different units, simulation and comprehensive diagnosis and service functions.
The HART /VVO-communication for the parameter adjustment via a handheld or laptop is integrated as a standard feature. These instruments are also available with the option of Profibus PA interface.
The Vegabar Series is available in the measuring ranges of 0-10 to 0-6000 kPa as well as for relative as well as absolute pressure applications. Accuracy classes 0,25 and 0,1 are also available. European standards mean the instruments can also be used in hazardous areas as well as in applications with special hygienic requirements.
