The Domestic Force Behind Power System Security: Songnuo Alliance Pressure Sensors Safeguard the Critical Energy Infrastructure
2026-08-26
From the steam‑powered pipeline networks of thermal power plants to the primary circuit of nuclear reactor cores, and on to the sprawling network of substations—power systems, as the lifeblood of the national economy, must operate safely and efficiently to safeguard both the nation’s economic well‑being and the public’s livelihood. Behind this vast and intricate energy infrastructure, pressure sensors serve as indispensable “guardians.”
PART 01 The Invisible Challenge:
Why does the power system require high-performance pressure monitoring?
Pressure sensors are critical foundational components that ensure the safe, efficient, and intelligent operation of the energy and power industries. At the generation end, thousands of pressure points in steam turbines, feedwater systems, and steam distribution networks require precise control; in the substations, parameters such as the sulfur hexafluoride‑insulated pressure of high‑voltage switchgear and transformer oil pressure directly affect equipment safety; and in the nuclear power sector, the primary circuit of a reactor places the highest possible demands on sensor performance, requiring exceptional resistance to high temperatures, radiation, and long‑term stability.
Traditional pressure sensors often suffer from zero-point drift, reduced accuracy, and shortened service life under harsh operating conditions such as high temperatures, intense radiation, and strong electromagnetic interference, posing a persistent challenge to the safe operation of power grids. Meanwhile, the high-end sensor market has long been dominated by foreign giants, leaving China heavily reliant on imports for mid- to high‑end sensors. This critical bottleneck is precisely the issue that Songnuo Meng Technology is committed to addressing.
PART 02 Songnuo Alliance’s Answer:
Nanofilm technology redefines pressure sensing.
Songnuo Meng Technology Co., Ltd. is a high-tech enterprise with fully independent intellectual property rights, specializing in the research, development, manufacturing, and sales of high-performance nanofilm sensors. The company’s proprietary nanofilm technology achieves atomic‑level bonding between the sensing element and the elastomer, fundamentally addressing the zero‑point drift issue that plagues conventional sensors due to frictional sliding at the interface between these components.
Based on this core technology, Songnuomeng has developed a portfolio of pressure‑monitoring products tailored for power‑system applications:
CYB-S650 Series Intelligent Pressure Transmitter
— The “Precision Sentinel” of the power generation sector
In conventional power generation sectors such as thermal and hydroelectric power, the pressure parameters at various nodes in steam turbines, feedwater systems, and steam distribution networks are directly linked to both generation efficiency and operational stability.
The CYB‑S650 series intelligent pressure transmitters feature a high‑performance sensor core and active temperature compensation, offering exceptional accuracy, minimal temperature drift, and excellent long‑term stability. With measurement accuracy as high as 0.075% of full scale, their all‑stainless‑steel 316L hermetically welded construction ensures a high degree of protection, making them well suited for outdoor and harsh environments. The devices support HART communication, enabling remote zeroing and span adjustment, and are certified for explosion‑proof applications, delivering both robust reliability and operational safety in demanding industrial settings.

CYB-S680L Series Wireless Smart Pressure Transmitter
——The Unmanned “Remote Eye”
For distributed, unattended scenarios such as substations, the CYB‑S680L series wireless smart pressure transmitters offer an ideal solution.
This is an ultra-low-power, LCD‑displayed smart pressure transmitter with wireless communication capabilities. It supports multiple network options, including NB‑IoT, 4G, and 5G, and can transmit data such as pressure readings, alarm thresholds, battery voltage, Beidou‑based location coordinates, and signal strength. Users can view data and configure parameters via magnetic‑control buttons, PC software, Bluetooth apps, or wireless communication. The device operates maintenance‑free for several years, making it ideally suited for real-time pressure monitoring in harsh outdoor environments.
