Nuclear power electricity

As a core foundational component, the pressure sensor is critical to ensuring the safe, efficient, and intelligent operation of the energy and power industry. It provides comprehensive coverage across various power generation scenarios—from conventional thermal and hydroelectric power to nuclear, photovoltaic, wind, and distributed energy systems. The sensor’s highly accurate measurement data directly forms the basis for unit control and intelligent dispatch decisions, providing indispensable sensing support for the smart transformation of power plants.

In the nuclear power industry, pressure transmitters are widely used in both safety-related and non-safety-related instrumentation systems to continuously monitor critical parameters such as pressure and differential pressure (used for deriving flow rate and liquid level), thereby providing reliable signals for reactor protection systems and post-accident monitoring systems. Due to the extremely unique operating environment of nuclear power plants, the transmitters employed must possess exceptional capabilities, including resistance to continuous radiation exposure, immunity to design-basis earthquakes, tolerance to high-temperature and high-pressure steam surges, resistance to chemical sprays, and long-term stable operation under high pressure. These demanding conditions place the highest technical requirements on measurement accuracy, long-term stability, and overall reliability of these transmitters.

Relevant typical cases

Developed independently through cooperation between Sensor Nobleman and China National Nuclear Corporation, the “semiconductor-like nano-film strain-type pressure transmitter” boasts fully independent intellectual property rights and is fully comparable to internationally renowned nuclear-grade products. It can withstand gamma-ray irradiation up to 200 M rad, and its performance metrics—including measurement accuracy, long-term stability, and environmental adaptability—fully meet the requirements for nuclear power applications. Currently, the product has successfully passed rigorous performance tests and is being deployed in multiple nuclear power enterprises, receiving widespread acclaim from users.

The high-performance pressure switch products developed by Sensor Nobleman are benchmarked against well-known domestic brands (SOR and WEDOMORE). The product’s measurement accuracy, repeatability, hysteresis, and other key indicators all meet internationally advanced standards and can be widely used in fields such as nuclear power and thermal power.
