ABB pressure transmitter Safety-Critical Transmitters 268DD

Model 268DD Safety-Critical differential/gauge pressure transmitter features a direct mount diaphragm seal. Taylor’s “All-Welded” diaphragm seal manufacturing technology optimize in-field performances. The enhanced 268 is the safest pressure transmitter on the market today.

Users have a wide selection of options such as fill fluids and wetted materials that allow total flexibility. ABB, leader in severe process measurements, is able to provide the right solution for the most critical process media at extreme ambient and process conditions. The 268DD grants long-term stability and high performances where safety is the priority.

Thanks to the IEC61508/ISA S84.01 certification and the hardware/software redundancy with MTBF of over 100 years, the 268DD represents the smartest solution in Safety loop applications.
268DD is certified for use in SIL2 (1oo1) and SIL3 (1oo2 redundant configuration) loops.
