The ABB 266GRT is a premium gauge pressure transmitter integrated with advanced remote diaphragm seals, tailored to deliver exceptional measurement performance in the most challenging industrial environments. Engineered by ABB, a global leader in industrial automation and measurement technologies, this transmitter is specifically designed for accurate measurement of liquid, gas, or steam pressure, as well as liquid level in open tanks, making it an indispensable solution for industries where process media is corrosive, viscous, or prone to solidification.
At the heart of the 266GRT’s performance is its integration of Taylor’s renowned "all-welded" remote seal technology, which ensures superior resistance to harsh process conditions while maintaining leak-tight integrity. This design eliminates the risk of contamination and ensures reliable operation even when dealing with aggressive media such as chemicals, slurries, or high-temperature fluids. Complemented by ABB’s proprietary Through-the-Glass (TTG) configuration capability, the 266GRT allows for safe and convenient on-site parameter setting without opening the transmitter’s housing, significantly enhancing operational safety and efficiency in hazardous areas.
Precision and stability are hallmarks of the 266GRT. With a base accuracy of ±0.04% of calibrated span (and an optional high-precision version reaching ±0.025%), combined with a 10-year stability guarantee, the transmitter delivers consistent and trustworthy data over extended periods, minimizing the need for frequent calibrations and reducing maintenance costs. Its impressive turndown ratio of up to 100:1 ensures flexibility across a wide range of measurement spans, from 0.6 kPa to 60,000 kPa, adapting seamlessly to diverse process requirements.
Reliability and ease of maintenance are embedded in every aspect of the 266GRT’s design. The field-replaceable electronics module features auto-configuration, enabling quick replacement in minutes without the need for complex reconfiguration—critical for minimizing downtime in mission-critical applications. Equipped with in-built advanced diagnostic functions, the transmitter provides real-time monitoring of system health, alerting operators to potential issues such as seal failures or impulse line blockages before they escalate into costly process disruptions.
The 266GRT is built to meet global safety and compliance standards, including TÜV Nord certification for IEC 61508 (SIL 2 for single-transmitter configurations and SIL 3 for redundant setups), PED Category III, and RoHS II compliance. It supports multiple communication protocols, including 4-20 mA HART, PROFIBUS PA 3.01, and Foundation Fieldbus ITK 5.1/6.x, ensuring seamless integration with existing control systems.
