The 266MRT is a differential pressure transmitter equipped with a remote-mounted diaphragm seal and multi-sensor technology. It is suitable for measuring the flow rate, liquid level, pressure, and density of liquids, gases, or vapors. Its unique design integrates multiple sensors into a single instrument, enabling simultaneous measurement of differential pressure and absolute pressure. The temperature sensor and absolute pressure measurement can also be used to eliminate the impact caused by the environment.

By adopting Taylor’s fully welded technology in the design and production of diaphragm seals, the 266MRT 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.

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

The 266MRT 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.
