In high-temperature environments in the power industry, level measurement faces severe challenges. The BP-801K high-temperature guided-pressure level transmitter adopts a stainless steel cable-cylinder design, specially engineered for ultra-high-temperature water level measurement, ensuring accuracy and reliability. This article provides an in-depth discussion of its practical applications in the power industry, offering professional reference for technical evaluators.

Core pain points of high-temperature level measurement in the power industry

Scenarios such as thermal power plant boiler systems and nuclear power station cooling circuits often face extreme operating conditions above 300℃, where traditional level sensors are prone to signal drift, seal failure, and other issues. According to ASME B31.1 standard requirements, such environments must simultaneously meet three key indicators: long-term temperature resistance ≥400℃, protection rating above IP68, and annual stability error ≤0.1%FS. The BP-801K adopts a 316L stainless steel cable-cylinder structure and achieves zero leakage through an integral forging process. Its built-in MC20CD high-temperature guided-pressure module effectively suppresses thermal expansion interference, and tests show it still maintains 0.25 accuracy at 450℃.

In-depth analysis of technical performance

Compared with similar products such as SP-814 and HDP601H, the BP-801K stands out in the following parameters: medium temperature range -50~450℃ (extended version up to 550℃), response time ≤3ms, and measuring range covering 0-50m water column. Its core advantage lies in the innovative dual-cavity isolation design—the high-pressure side adopts the patented YM-GLYW guided-pressure structure, while the low-pressure side is equipped with a YM-RGYW temperature compensation unit, keeping temperature drift within ±0.03%FS/℃. Test data show that after 8000 hours of continuous operation in a desulfurization tower application at a coal-fired power plant, its output signal fluctuation amplitude was only 0.12% of full scale.

Typical application scenarios and selection guide

For different power industry scenarios, we recommend differentiated configuration solutions: for steam drum level monitoring, priority should be given to the KYB1903M1IC1-1 model with heat dissipation fins; for circulating water pump rooms, the MPM4809TD3E24 explosion-proof model is recommended; if simultaneous pressure parameter monitoring is required, it can be paired with domestic general-purpose pressure transmitter MIK-P300 compact LCD display pressure sensor to form an integrated system. It is worth noting that for applications in the nuclear power field, the YMC-116N all-stainless-steel welded version must be selected, as it complies with RCC-E nuclear-grade equipment certification requirements.

Successful cases and data verification

A 1000MW ultra-supercritical generating unit project adopted 12 BP-801K units for boiler steam drum water level monitoring, achieving three major improvements compared with the original imported equipment: installation cycle shortened by 40% (thanks to the Gl/2 male thread quick connector), maintenance cost reduced by 62% (the modular design supports online replacement), and measurement system availability increased to 99.97%. According to third-party testing, under rapid load-changing operating conditions of the generating unit, its transient response error was reduced by 78% compared with the traditional YM-CYYW model.
