Enables quick and easy local configuration without the need to open the cover - even in environments with explosion protection
This document is a technical datasheet for the ABB Model 266GST (Gauge) and Model 266AST (Absolute) pressure transmitters. These devices are part of the 2600T series and are engineered to provide accurate measurement solutions for various industrial applications.
Key features highlighted include a base accuracy of 0.04% of calibrated span, a proven sensor technology with a large turn-down ratio up to 100:1, and a stability of 0.15% over 10 years. The transmitters support flexible configuration options, including local setup via keys on the LCD indicator without needing to open the cover, even in explosion-protected environments.
