The 266ART is a high-performance transmitter for absolute pressure measurement, sealed with a diaphragm.

Due to the use of Taylor’s fully welded technology in the design and production of the diaphragm seal, the 266ART offers unparalleled superior performance and a wide selection of filling liquids, diaphragm materials, capillary protection types, and process connections.

As a leader in the measurement of harsh conditions, ABB can provide the most suitable solutions for critical application points under harsh environmental and process conditions. The 266ART, with its long-term stability and reliability, is an ideal solution for absolute pressure measurement.In addition to pluggable terminal blocks, the transmitter’s electronic circuit board features a self-configuration function, allowing for on-site replacement to improve factory efficiency. The unique hot-swappable on-site display enables very convenient configuration settings, helping customers save time and maintenance and spare parts costs. Moreover, the innovative TTG window technology allows for on-site operations without opening covers in explosion-proof situations, saving a significant amount of time.The 266ART has obtained SIL2/SIL3 certification issued by TUV Nord under the IEC61508 standard.

The transmitter meets the SIL2 safety level when used as a single instrument (1oo1) and can reach the SIL3 safety level under redundant configurations (1oo2).- Basic accuracy: ±0.04%- Range limit: 1.2 to 10000 kPa-a- Output signal: Multiple protocol platforms with interoperability and upgrade capability. – 4-20mA HART – Profibus PA – Foundation Fieldbus ITK5.1- LCD with TTG window technology, allowing for setting operations without opening the cover- Compliant with IEC61508 SIL2/SIL3 certification- Compliant with PED Class III
