The safety and economic benefits of a power plant depend on the continuous and stable output of its instruments. In ultra-supercritical units, the environment at high-pressure measurement points is harsh-a mix of high temperature, high pressure, and vibration, with complex and variable media. Frequent drift or even failure of an instrument under extreme conditions not only imposes a heavy maintenance burden but can also become a trigger for unplanned shutdowns.
The outstanding reliability and stability of the 3051S high static pressure transmitter are its irreplaceable core value in the long-term operation of power plants.
Long-Term Stability and Low Drift: Reduced Maintenance, Safeguarding Continuous Operation
Power plant overhaul cycles often last for several years, during which instruments are required to output reliable data without frequent calibration.
Taking the 3051S+P0 high static pressure differential pressure transmitter as an example, its maximum permissible working pressure (MWP) reaches 42MPa, covering the actual static pressure environment of over 35MPa in the main feedwater system of ultra-supercritical units. Meanwhile, its long-term stability commitment reaches 15 years / ±0.15% URL, meaning that from one major overhaul to the next, there is no need for intervention due to instrument drift. This significantly reduces maintenance costs and fundamentally eliminates the potential for control system malfunctions caused by measurement deviations.
Adapting to Complex Operating Conditions: Isolating High-Temperature Media and Balancing Temperature Influences.
High-pressure measuring points in ultra-supercritical units often involve switching between high-temperature media and complex operating conditions. The 3051S transmitter not only withstands high pressure, but its accompanying dual-chamber housing, remote transmission flange, and other accessories are specially designed to effectively isolate high-temperature steam and balance the influence of temperature fluctuations on measurements, ensuring the instrument itself remains in a suitable operating condition for extended periods.
More importantly, during the startup of a once-through boiler and the transition between wet and dry operating conditions, the liquid level changes in the steam drum and water-cooled walls are drastic and rapid. The 3051S transmitter, with its 0.025% reference accuracy and a wide range ratio of up to 200:1, provides continuous and reliable monitoring signals during this process, supporting operators in accurately grasping the working fluid status and serving as a crucial guarantee for flexible peak shaving and safe transition of the unit.
Reliability: The Silent Foundation of a Power Plant's Long-Term Competitiveness.
Safety is the bottom line, economy is the lifeline, and reliability is the foundation for the long-term maintenance of both.
The 3051S high static pressure transmitter, with its comprehensive capabilities of low drift, resistance to harsh environments, and adaptability to complex operating conditions, silently safeguards every critical measuring point in the power plant over its years of operation. Investing in its reliability is essentially an investment in the unit's long-term stable operation and overall life-cycle benefits.
