The 268VR is the “Enhanced Version” of ABB 268 Safety-Critical absolute pressure transmitter with diaphragm seal. Thanks to the longstanding expertise as well as to Taylor’s “All-Welded” diaphragm seal technology, this pressure transmitter is the safest process instrument on the market today since it offers unmatched performances.
268VR has been designed and manufactured according to the IEC61508/ISA S84.01 which fixes diagnostic, safety and reliability parameters.
ABB, leader in severe process measurements, is able to provide the right solution for the most critical process media at extremely varying ambient conditions and, in the meantime, to offer a wide range of selectable options: filling fluids, diaphragm material, capillary protection etc. The TÜV certification gives users the guarantee of how many attention ABB put on Safety.
Moreover, it can be used in SIL3 when installed in a redundant (1oo2) configuration.
