ABB 266GST Gauge Pressure Transmitter

The ABB 266GST Gauge Pressure Transmitter is a cutting-edge industrial measurement device engineered by ABB, a global leader in automation and control technologies, to deliver unparalleled accuracy, stability, and reliability for gauge pressure monitoring across diverse industrial sectors. Designed to meet the rigorous demands of modern manufacturing, oil and gas, chemical processing, and power generation industries, the ABB 266GST Gauge Pressure Transmitter combines proven sensor technology with state-of-the-art digital capabilities, ensuring consistent performance even in extreme ambient and process conditions. Whether measuring liquid, gas, or steam pressure, or monitoring liquid levels in open tanks, this transmitter stands out as a top-choice solution for businesses seeking to optimize operational efficiency, reduce maintenance costs, and ensure compliance with industry standards.

At the core of the ABB 266GST Gauge Pressure Transmitter lies its exceptional measurement accuracy, a key feature that sets it apart from conventional pressure transmitters. The base accuracy of the ABB 266GST Gauge Pressure Transmitter is ±0.04% of the calibrated span, with an optional high-accuracy version offering ±0.025% for applications requiring the most precise readings conceivable. This level of accuracy is sustained over extended periods, thanks to the transmitter’s 10-year stability rating, which minimizes the need for frequent recalibration and reduces downtime in critical industrial processes. Complementing its accuracy is a remarkable turndown ratio of up to 100:1, allowing the ABB 266GST Gauge Pressure Transmitter to adapt to a wide range of measurement spans without compromising performance—a versatility that makes it suitable for both high-pressure and low-pressure applications alike.

The ABB 266GST Gauge Pressure Transmitter offers comprehensive sensor options to accommodate diverse industrial requirements, with a full range of span limits and upper range limits (URL) tailored to different pressure measurement needs. Below is a detailed breakdown of its functional specifications, including sensor codes, measurement ranges, and minimum spans:

Sensor Code	Upper Range Limit (URL) – 266GST	Lower Range Limit (LRL) – 266GST	Minimum Measuring Span – 266GST
C	6 kPa (60 mbar, 24 inH2O)	-6 kPa (-60 mbar, -24 inH2O)	0.2 kPa (2 mbar, 0.8 inH2O)
F	40 kPa (400 mbar, 160 inH2O)	-40 kPa (-400 mbar, -160 inH2O)	0.4 kPa (4 mbar, 1.6 inH2O)
L	250 kPa (2500 mbar, 1000 inH2O, 14.5 psi)	-100 kPa (-1 bar, -14.5 psi)	2.5 kPa (25 mbar, 10 inH2O)
D	1000 kPa (10 bar, 145 psi)	-100 kPa (-1 bar, -14.5 psi)	10 kPa (100 mbar, 1.45 psi)
U	3000 kPa (30 bar, 435 psi)	-100 kPa (-1 bar, -14.5 psi)	30 kPa (0.3 bar, 4.35 psi)
R	10000 kPa (100 bar, 1450 psi)	-100 kPa (-1 bar, -14.5 psi)	100 kPa (1 bar, 14.5 psi)
V	60000 kPa (600 bar, 8700 psi)	-100 kPa (-1 bar, -14.5 psi)	600 kPa (6 bar, 87 psi)

For optimal measuring accuracy, it is recommended to select the sensor code that provides the lowest turndown (TD) value, ensuring the ABB 266GST Gauge Pressure Transmitter operates at its peak performance for specific application needs. Additionally, the transmitter supports zero position suppression and elevation, allowing the zero position and span to be set to any value within the listed measurement range limits, provided the adjusted span is equal to or greater than the minimum span for the selected sensor code.

Beyond its core measurement capabilities, the ABB 266GST Gauge Pressure Transmitter is equipped with advanced functional features that enhance usability and operational efficiency. It includes configurable damping with a time constant between 0 and 60 seconds, which can be adjusted to complement the sensor’s response time and accommodate different process dynamics. The transmitter boasts a fast turn-on time of less than 10 seconds with minimum damping, ensuring it is ready for operation quickly after power-up, minimizing disruptions to industrial processes. Its insulation resistance exceeds 100 MΩ at 500 V DC (between terminals and ground), providing robust electrical protection and ensuring reliable performance in harsh electrical environments.

The ABB 266GST Gauge Pressure Transmitter also incorporates innovative configuration and diagnostic features that simplify maintenance and reduce operational costs. It features TTG (Through-the-Glass) key technology, which allows for quick and easy local configuration via keys on the LCD indicator—eliminating the need to open the cover, even in explosion-protected environments. This intuitive plug-and-play design, combined with an in-field replaceable electronics module and auto-configuration functionality, dramatically improves plant productivity by reducing maintenance time and inventory costs. The transmitter’s built-in advanced diagnostics provide real-time insights into its performance, enabling proactive maintenance and minimizing unplanned downtime—a critical advantage for industries relying on continuous operation
