The 266AST is a high-performance transmitter designed for absolute pressure measurement, suitable for applications involving liquids, gases, and vapors. It offers a wide range of options, such as oil filling and wetted materials, and is well-suited for critical measurement points under harsh operating conditions. Its typical features include long-term stability and reliability.

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 266AST 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.
