ABB 266NRH Absolute pressure transmitter

ABB 266NRH Absolute pressure transmitter

As a leader in industrial measurement technology, ABB delivers the ABB 266NRH Absolute pressure transmitter, a high-overload absolute pressure measurement device engineered to excel in the most demanding industrial environments. Designed with remote diaphragm seal construction, the ABB 266NRH Absolute pressure transmitter is specifically tailored for measuring liquid, gas, or steam flow, as well as level, pressure, and density, making it a versatile choice for industries ranging from offshore oil and gas to pharmaceutical laboratories and chemical processing plants. With its combination of unmatched performance, long-term stability, and smart functionality, the ABB 266NRH Absolute pressure transmitter stands out as a reliable solution for critical absolute pressure measurement needs, helping businesses optimize process efficiency and reduce operational costs.

The ABB 266NRH Absolute pressure transmitter incorporates Taylor’s proprietary “all-welded” remote seal technology, a key feature that enhances its durability and performance in harsh process conditions. This advanced seal manufacturing technique, paired with ABB’s decades of expertise in severe process measurements, ensures the transmitter delivers consistent, accurate results even when exposed to extreme ambient temperatures, corrosive media, and high-pressure environments. Unlike standard pressure transmitters, the ABB 266NRH Absolute pressure transmitter offers a wide range of customizable options, including fill fluids, diaphragm materials, capillary protection, and mounting connections, allowing it to be tailored to the unique requirements of nearly any application.

One of the most notable advantages of the ABB 266NRH Absolute pressure transmitter is its smart design, which prioritizes ease of use and operational efficiency. The transmitter features an in-field replaceable electronics module with auto-configuration functionality, enabling quick and hassle-free maintenance without the need for factory recalibration—dramatically improving plant productivity and minimizing downtime. Additionally, its intuitive plug-and-play display, equipped with innovative TTG (Through the Glass) technology, allows users to configure the instrument in the field without removing the windowed front cover, saving valuable time and maintaining safety in hazardous or explosive environments.

Safety is a top priority in industrial operations, and the ABB 266NRH Absolute pressure transmitter meets the highest safety standards to ensure protection in critical applications. It holds SIL 2 / SIL 3 certification issued by TÜV Nord according to IEC 61508, making it an ideal choice for safety-critical loops where reliability and protection are non-negotiable. The transmitter also fully complies with PED Category III, further validating its ability to perform safely and effectively in high-risk industrial settings.

For seamless integration into existing process control systems, the ABB 266NRH Absolute pressure transmitter supports multiple communication protocols, including HART®, Profibus PA, Foundation Fieldbus, and WirelessHART. The WirelessHART option eliminates the need for complex wired infrastructures, reducing installation time and overall implementation costs while providing reliable, real-time data transmission. When configured with WirelessHART, the ABB 266NRH Absolute pressure transmitter offers a battery life of approximately 10 years at 32-second update rates, delivering a cost-effective and low-maintenance solution for remote or hard-to-reach measurement points.
