The 266GRT is a high-performance transmitter with a diaphragm seal designed for gauge pressure measurement.

By adopting Taylor’s fully welded technology in the design and production of diaphragm seals, the 266ART delivers unparalleled performance and offers a wide range of options in terms of fill fluids, diaphragm materials, capillary protection types, and process connections. As a leader in harsh-condition measurement, ABB is capable of providing appropriate solutions for critical application points under harsh environmental and process conditions. The 266ART stands out for its long-term stability and reliability, making it an ideal solution for absolute pressure measurement.

In addition to pluggable terminals, the transmitter’s electronic circuit board is equipped with a self-configuration function, enabling on-site replacement and improving plant efficiency. The unique hot-swappable on-site display allows for extremely convenient setup and configuration, helping customers save time as well as maintenance and spare parts costs. Furthermore, the innovative TTG window technology enables on-site operations in explosive-proof environments without opening the cover, saving a significant amount of time.

The 266GRT has obtained SIL2/SIL3 certificates issued by TUV Nord in accordance with the IEC 61508 standard. When a single instrument is used (1oo1), this transmitter meets the SIL2 safety level; in a redundant configuration (1oo2), it can reach the SIL3 safety level.
