ABB pressure transmitter Safety-Critical Transmitters 268NR

Model 268NR is the “Enhanced” Safety-Critical absolute pressure transmitter with remote seal. Thanks to the longstanding expertise as well as to the “All-Welded” technology inherited by Taylor in remote seal manufacturing as this Safety-Critical pressure transmitter is the safest process instrument on the market today since it offers unmatched performances.

268NR has been designed and manufactured according to the IEC61508/ISA S84.01 which fixes diagnostic, safety and reliability parameters.

Model 268NR is suitable for a broad selection of options, such as fill fluids and wetted materials, allowing total flexibility maximizing the cost-effective aspect, while also providing applications with critical process media at extended temperature ranges.

Configuration is via hand held terminal or PC configuration platform.
With TÜV SIL2 certification and applicable SIL3 (only for redundant configuration) the 268NR represents the smartest solution in Safety Instrumented Systems.
