4 20ma Pressure Gauge Transmitter

The 266GST is a high-performance gauge pressure transmitter within the versatile ABB 2600T series. It is engineered to provide exceptional accuracy and stability for liquid, gas, and steam applications. Featuring modular electronics and the innovative "Through-The-Glass" (TTG) technology, it allows for easy configuration without removing the cover, significantly enhancing safety and reducing maintenance time. As a robust 4 20ma pressure gauge transmitter, the 266GST integrates seamlessly into standard control loops, offering a plug-and-play solution that ensures long-term operational integrity and low total cost of ownership.

Key Features and Technical Specifications

Superior Accuracy: Delivers a standard base accuracy of ±0.04%, enabling tight control over critical processes.
Intuitive Interface: Equipped with TTG technology for touch-sensitive configuration directly through the window, eliminating the need to open the device in hazardous areas.
Advanced Diagnostics: Includes Plugged Impulse Line Detection (PILD) to identify blockage issues before they lead to failure.
Safety Certified: Compliant with IEC 61508 for SIL 2 (1oo1) and SIL 3 (1oo2) applications, providing built-in safety assurance.
Flexible Output: Supports multiple protocols including HART, PROFIBUS PA, and FOUNDATION Fieldbus alongside standard analog signals.

Industry Applications and Robust Design

The 266GST is indispensable for sectors such as Oil & Gas, Power Generation, and Chemical Processing. It excels in monitoring hydraulic skids, pipeline pressure, and open tank levels. Its rugged construction withstands high overpressure and aggressive media, with a wide selection of wetted materials like Hastelloy C-276 and Monel. By choosing this 4 20ma pressure gauge transmitter, operators ensure reliable communication with DCS and PLC systems, facilitating smarter asset management and consistent, high-quality production output.
