In modern industrial automated production, temperature is a core parameter for controlling process quality, ensuring equipment safety, and achieving energy conservation and consumption reduction. Traditional temperature measurement equipment is bulky, has complicated wiring, weak anti-interference capabilities, and limited adaptability, making it difficult to meet the production needs of confined equipment spaces, complex working conditions, and high-precision temperature measurement.

An integrated temperature transmitter consists of a resistance temperature detector (Pt100) or thermocouple sensing element, a transmitting circuit, and a protective sheath. It is a commonly used temperature measuring instrument in industrial settings.

Integrated temperature transmitters combine temperature sensing elements and transmission modules, directly converting RTD and thermocouple signals into 4-20mA standard current. They are widely used in on-site temperature measurement in chemical, heating, and metallurgical industries. However, they are prone to failure due to environmental factors, wiring issues, and component aging. Proper maintenance can significantly extend their service life.

Water pumps are core power equipment in thermal power, cogeneration, and industrial heating systems, undertaking the critical task of pressurizing the water supply to the unit. Feedwater pumps are high-speed, heavy-duty, and precision equipment; their core components, such as bearings and shaft seals, rely on a continuous lubrication and cooling system.

In building and industrial fire protection systems, the stable pressure of various fire water supply, sprinkler, and pressure stabilization networks is the core guarantee for fire emergency response. Fire protection systems are in a standby state most of the time, and are activated when there is no fire. However, hidden problems such as pipeline pressure leakage, pump failure, pipeline damage, and pressure stabilization failure are easily overlooked.

The water treatment system encompasses multiple process scenarios, including tap water purification, wastewater treatment, reverse osmosis pure water production, and circulating water reuse. The system’s operation relies on stable pipeline pressure to ensure the normal operation of processes such as filtration, pressurization, disinfection, and transportation. Pressure is a core parameter for the operation of water treatment equipment; abnormal pressure can lead to problems such as pump dry running, membrane element damage, pipeline leaks, and process failure.

During industrial signal acquisition, pressure sensors generate various inherent noises within their circuitry. These are inherent interferences of the device itself and cannot be completely eliminated, directly affecting measurement accuracy and signal stability.

Pressure switches are fundamental and core monitoring and protection components in industrial automation pressure control systems, widely used in numerous industries such as chemical, mining, water conservancy, HVAC, and machinery manufacturing. Compared to precision electronic devices such as pressure sensors and transmitters, pressure switches are simpler in structure, more practical, and adaptable to a wider range of scenarios. They can monitor pipeline and equipment pressure changes in real time, enabling automatic start/stop, pressure protection, fault alarms, and safety interlocks. With their stable and reliable performance, low operating costs, and strong environmental adaptability, pressure switches have become the preferred equipment for industrial pressure control. Their core advantages are mainly reflected in high reliability, rapid response, strong adaptability, simple operation and maintenance, good safety, and outstanding cost-effectiveness.

The chemical production industry is a typical high-risk field, with flammable and explosive gases, volatile flammable liquids, corrosive media, and high temperature and high pressure conditions commonly present throughout the entire process of production, storage, transportation, and reaction.
