Superior Accuracy and Long-Term Stability for Critical Applications

Advanced Sensor Technology Ensures Precise Measurements

The Rosemount™ 3051TG direct connection pressure transmitter incorporates cutting-edge capacitive sensor technology that delivers unparalleled accuracy in pressure measurement applications. This advanced sensor design utilizes a patented silicon crystal structure that responds precisely to pressure changes, converting mechanical force into electrical signals with remarkable consistency. The capacitive sensing mechanism operates on the principle of measuring changes in capacitance between two conductive plates separated by a dielectric material, where pressure variations cause minute deflections in the sensing diaphragm, resulting in proportional capacitance changes. This technology provides exceptional linearity and minimal hysteresis, ensuring that pressure readings remain accurate across the entire measurement range. The sensor's temperature compensation algorithms automatically adjust for thermal effects, maintaining measurement integrity even when exposed to the wide temperature variations common in refinery operations. Furthermore, the silicon crystal construction offers superior chemical resistance and mechanical durability, making the Rosemount™ 3051TG direct connection pressure transmitter ideal for monitoring corrosive fluids and gases typically encountered in petroleum processing applications.

Ten-Year Stability Reduces Maintenance Requirements

One of the most significant advantages of the Rosemount™ 3051TG direct connection pressure transmitter is its proven ten-year stability specification, which represents a substantial improvement over traditional pressure measurement solutions. This exceptional long-term stability is achieved through rigorous manufacturing processes that include precision machining of sensor components, careful selection of materials with matched thermal expansion coefficients, and comprehensive aging procedures that eliminate drift-inducing stresses. The transmitter's stability specification ensures that measurement accuracy remains within specified limits for a decade after installation, dramatically reducing the frequency of recalibration requirements and associated maintenance costs. This stability is particularly crucial in refinery applications where process upsets caused by measurement drift can result in significant economic losses and safety concerns. The extended stability period allows refineries to implement predictive maintenance strategies rather than reactive approaches, optimizing maintenance schedules and reducing unplanned downtime. Additionally, the reduced need for frequent calibration checks minimizes personnel exposure to hazardous areas, contributing to improved workplace safety while maintaining measurement integrity throughout the transmitter's operational life.

Wide Rangeability and Flexible Configuration Options

The Rosemount™ 3051TG direct connection pressure transmitter offers exceptional rangeability with a 1500:1 turndown ratio, providing unprecedented flexibility in application configuration and future process modifications.

The transmitter's ability to measure pressures up to 1,378.95 bar (20,000 psi) makes it suitable for high-pressure applications commonly found in refinery processes such as hydrotreating, catalytic cracking, and hydrogen compression systems. The flexible configuration capability enables process engineers to optimize measurement ranges for specific applications, maximizing resolution and accuracy for critical control loops. The transmitter supports both gauge and absolute pressure measurements, with application-specific configurations that can transform the device into a level measurement solution with integrated volume calculation functions. This versatility is particularly valuable in refinery applications where process conditions may change over time, allowing the same transmitter to accommodate modified operating parameters without requiring hardware replacement. The configuration flexibility extends to output signals, supporting both analog and digital communication protocols to integrate seamlessly with existing control systems.
