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 intelligent transformation of power plants.
In the petrochemical industry, pressure sensors and transmitters—often likened to “nerve endings” scattered throughout critical equipment—are the core sensing components that enable safe, efficient, and intelligent production. These devices are precisely installed on equipment such as core samplers, reactors, distillation columns, pipelines, and storage tanks, continuously and accurately converting pressure signals from high-temperature, high-pressure, corrosive, or flammable and explosive media into standardized electrical signals. This real-time data not only serves as the foundation for monitoring process conditions and optimizing production control but also forms an essential part of safety interlock systems. In the event of abnormal pressure readings, these systems can immediately issue alarms or trigger shutdowns, effectively preventing catastrophic accidents such as leaks and explosions and providing indispensable assurance for the stable and long-term operation of the entire petrochemical industry.
In the modern shipbuilding industry, the sophistication of sensor technology not only directly determines the safety of vessel navigation, operational efficiency, and adaptability to marine environments, but also serves as a key indicator for measuring a country’s core competitiveness in the shipbuilding sector and its influence in maritime strategic discourse. Today, the total carrying capacity of the global merchant fleet has surpassed 2 billion tons, with an annual shipping volume reaching 12 billion tons. Over 30,000 vessels of various types are constantly plying the world’s ocean routes, day and night. Currently, a 100,000-ton bulk carrier must be equipped with more than 2,500 independent sensors, while a 300,000-ton oil tanker requires over 4,000 sensors. For deep-sea research vessels and military ships, the number of sensors can exceed 5,000, widely distributed across critical areas such as propulsion systems, navigation and positioning, environmental conditions, structural integrity, and cargo monitoring.
As the cornerstone of the modern technology industry, semiconductor manufacturing pursues extreme precision in its processes. From wafer processing and photolithography to etching, thin-film deposition, and packaging and testing, every step must be carried out in an ultra-high-purity environment that is nearly exacting. Even minor fluctuations in pressure parameters can, at best, lead to non-uniform thin films or deviations in etching rates, and at worst, result in the outright scrapping of an entire batch of wafers—making pressure control a critical factor affecting yield. Particularly in front-end processes, the precise control of ultra-pure, highly toxic, and strongly corrosive specialty gases such as SiH₄, PH₃, AsH₃, ClF₃, and HF places near-extreme demands on the performance of pressure sensors.
In the aerospace field, sensors serve as the “sensory nerves” of aircraft, playing a critical role as foundational components that ensure mission safety and system reliability. They operate steadily under extreme environmental conditions, providing indispensable data support for aircraft design validation, real-time control, and condition monitoring. In aerospace systems, pressure sensors are integrated throughout the entire lifecycle of launch vehicles, satellites, space stations, and deep-space probes, continuously monitoring the pressures in fuel tanks, propulsion lines, and combustion chambers, while also ensuring stable cabin pressure and precise attitude control in the on-orbit environment. In the aviation sector, sensors likewise perform vital functions, supplying atmospheric data to flight control systems, monitoring engine operating conditions, and maintaining the safety of the cabin environment and hydraulic systems. Faced with severe challenges such as intense vibrations, extreme temperatures, and high g-forces, aerospace sensors must simultaneously exhibit multiple demanding performance characteristics: high precision, long-term stability, exceptional shock resistance, wide-temperature-range adaptability, as well as lightweight design and high reliability.
As global agriculture accelerates its transition toward precision and intelligence, sensors—acting as the “sensing core” of modern agricultural machinery—deeply empower the enhancement of agricultural production efficiency and sustainable development. In key equipment such as high-end tractors and intelligent harvesting machines, pressure sensors monitor critical parameters—including hydraulic, transmission, and braking systems—in real time, converting mechanical conditions into precise signals that serve as the foundational support for achieving autonomous driving, variable-rate operations, and intelligent early warning systems. SunnoM’s solutions have been deeply integrated into various systems of agricultural machinery, playing a particularly vital role in engine systems as “heart monitors,” continuously safeguarding oil pressure in real time. With product characteristics featuring high reliability, robust resistance to strong vibrations, and exceptional overload capacity, our sensors are designed to withstand the harshest field conditions—such as extreme heat or cold, high humidity, and high altitudes—providing solid and dependable sensing support for the stable operation of smart agricultural machinery and the advancement of agricultural modernization.
In modern rail transit systems, sensors serve as the core foundation for ensuring the safe, efficient, and intelligent operation of trains. As global rail networks evolve toward higher speeds, heavier loads, and greater intelligence, the demand for precise sensing and control in high-speed trains has reached an unprecedented level. A modern high-speed train set requires the deployment of over 3,000 sensors—covering everything from traction power and braking control to monitoring the operating environment—thus comprehensively establishing a “neural network” for train operations. The sophistication of sensor technology directly determines the safety, punctuality, and operational and maintenance efficiency of rail transit systems, making it a critical technological cornerstone driving the modernization of rail transport.
As the core equipment for modern infrastructure construction and engineering operations, construction machinery often faces harsh challenges in its operating environment, including high vibration, heavy dust, drastic temperature fluctuations, and extreme loads. To ensure the safety, operational accuracy, and efficiency of these machines under complex working conditions, sensors have become a critical foundation for achieving intelligent operation and precise control of the entire machine. In key areas such as engine monitoring, hydraulic system management, transmission systems, and overall machine condition assessment, sensors—such as pressure, temperature, and displacement sensors—continuously collect real-time system status parameters and convert them into standardized signals. These signals provide essential data support for power optimization, precise motion control, fault early warning, and health management, making sensors the pivotal enabling component driving the transformation of construction machinery from “traditional mechanical drive” to “intelligent electro-hydraulic control.”
In the context of rapid advancements in industrial automation and intelligent equipment, the robotics industry is now entering a new wave of technological transformation and industrialization. Among these developments, torque sensors—essential components for robots to achieve precise force control and intelligent interaction—are playing a pivotal role in fields such as collaborative robots and humanoid robots. Not only do they enable real-time monitoring of joint torques, ensuring safe human-robot collaboration, but they also support advanced functions like drag teaching and end-effector force control, endowing robots with flexible and adaptive operational capabilities. By integrating cutting-edge control strategies—such as direct force control and hybrid position/force control—into their systems, torque sensors help robots achieve true dynamic responsiveness and intelligent task execution, driving the evolution of robotics from “repetitive execution” toward “autonomous adaptation.”
