Related papers demonstrate its potential for environmental monitoring in remote areas.   AI empowerment allows temperature data to generate deeper value. Through machine learning algorithms, sensor data streams can predict industrial equipment failures, optimize supply chain cold chain management, and even assist climate modeling. Several research reports in early 2026 highlighted the commercial transformation cases of "sensing-analysis-decision" closed-loop systems.   Substantial progress has also been made in applications for extreme environments. High-temperature-resistant ceramic composite materials and distributed optical fiber temperature measurement technology have been successfully used in aerospace engine monitoring and deep-sea exploration equipment, expanding the boundaries of human perception under harsh conditions.   From academia to industry, temperature sensors are evolving from simple measurement tools to the "nerve endings" of intelligent systems. With the collaborative advancement of materials science, wireless communications and data analysis technology, this basic device will continue to play a key role in sustainable development, health care and cutting-edge exploration.   Note: The content is based on a review of public technical literature and industry analysis in the first half of 2026.

In the context of increasingly fierce competition in the global industrial automation market, product compliance and safety certification have become the core tickets for entering the international high-end market. Yuyao Huangong Automation Instrument Factory's international market expansion has recently received major good news: multiple series of intrinsically safe pressure transmitters and temperature transmitters produced by the company have successfully passed the EU ATEX explosion-proof certification, and at the same time met the safety integrity level (SIL) evaluation requirements under the IEC 61508 standard. The acquisition of these two heavyweight certificates has cleared the most critical technical and qualification obstacles for environmental instrumentation products to penetrate into overseas high-end markets such as Europe, the Middle East, and Southeast Asia, especially for applications in hazardous areas such as oil, natural gas, and chemical industries.          ATEX certification is a mandatory directive established by the European Union for equipment used in potentially explosive environments. It is known as the "safety passport" for entering the European market. It strictly evaluates the product's explosion-proof structure, safety clearance, surface temperature and other indicators to ensure that it will not become an ignition source in flammable and explosive gas or dust environments. SIL (Safety Integrity Level) certification measures the reliability level of instruments performing safety functions in safety instrumented systems, from SIL1 to SIL4. The higher the level, the lower the probability of dangerous failure. Obtaining these two certifications at the same time fully proves that the products of environmental engineering instruments not only have excellent performance under normal working conditions, but also have world-class reliability and safety in extremely critical situations involving the safety of personnel and assets.          During the certification process, the technical team of Environmental Engineering Instruments worked closely with the certification agency to conduct comprehensive and multi-dimensional review and testing of the product's design documents, material selection, production process, and quality management system. For example, in order to meet the SIL2 level requirements, the product's internal circuit adopts a special redundant design and fault self-diagnosis function; in order to meet the ATEX certification, the sealing of the shell, the width of the joint surface and the surface roughness have been precisely calculated and processed. This process itself is a comprehensive upgrade and refinement of product design and technical management.          The person in charge of the overseas business department said: "This is more than just getting two certificates. It marks that our product design concepts and quality systems are truly in line with the highest international safety standards. It allows our overseas customers and partners to choose 'environmental manufacturing' with complete confidence. Today Since the beginning of this year, we have felt the positive effects of certification, and the number of inquiries and cooperation intentions from overseas oil and gas projects and general engineering contractors has increased significantly. "It can be predicted that with the improvement of the international certification system, environmental engineering instruments will be more stable and far-reaching in their internationalization journey.

Yuyao Environmental Engineering Automation Instrument Factory recently officially announced that its new generation intelligent temperature and pressure integrated transmitter, which has been developed after years of research and development, has successfully achieved mass production and been put into the market. This new product, codenamed HG-WY100, marks a breakthrough in environmental instrumentation in the direction of highly integrated and intelligent industrial sensors, aiming to provide streamlined and more reliable solutions for customers in process industries such as petroleum, chemical industry, and electric power.          In traditional industrial sites, temperature and pressure are two core parameters that need to be monitored independently, which means that users need to install, wire and maintain two sets of equipment separately, which is not only costly, but also increases system complexity and failure points. The HG-WY100 intelligent temperature and pressure integrated transmitter launched by Environmental Engineering Instruments innovatively integrates a high-precision temperature sensing module and a stable and reliable pressure sensing unit into a compact housing. It uses a self-developed signal conditioning circuit and a highly integrated microprocessor chip to measure the temperature and pressure of the medium in the pipeline or equipment synchronously and in real time, and transmits the two calibrated standard signals to the upper system through a single 4-20mA analog output or the mainstream HART/RS485 digital communication interface.          The far-reaching significance of this move is that it not only simplifies the installation structure of field instruments, saving installation costs and space, but more importantly, through native synchronization and correlation analysis of temperature and pressure data at the same measurement point, it can provide a more accurate data basis for process optimization, energy efficiency management and early fault diagnosis. For example, in steam transportation pipelines, synchronously monitored temperature and pressure data can more accurately calculate the enthalpy value of superheated steam; in chemical reactors, the combination of the two can better reflect the reaction process and safety status.          The development of this product inherits the innovative genes of Environmental Instruments, which have relied on national-level scientific research support and integrated the experience of international experts since its establishment. The company's technical director said: "Our goal has always been to solve the actual pain points at customer sites. The birth of HG-WY100 is in response to the call for integrated and intelligent data sources in the Industrial Internet of Things (IIoT) era. It is not only a product, but also a key part of our efforts to build an efficient and intelligent perception layer for our customers." At present, this product has been successfully used in pilot projects of many large domestic chemical groups and has received good initial feedback.

Driven by the national "double carbon" strategy, large-scale energy storage power stations, as key infrastructure for stabilizing the new power system, are ushering in a construction peak. Recently, good news came from Yuyao Huangong Automation Instrument Factory. Its corrosion-resistant liquid level transmitter and pressure monitoring series products specially designed for harsh environments have been successfully used in the battery compartment and fire protection system of a large coastal energy storage power station in East China, providing vital sensory guarantee for the safe and stable operation of this national key project.          The energy storage power station is located along the coast, and the salt spray content in the ambient air is high, which is extremely corrosive to metal materials and electronic components. At the same time, energy storage batteries have almost stringent requirements for thermal management, leakage monitoring and safety warnings during operation. The core of the solutions provided by Environmental Instruments lies in the excellent environmental adaptability and long-term stability of its products. The pressure transmitter used for pressure monitoring of fire water tanks and pipelines uses a special 316L stainless steel isolation diaphragm and a fully sealed laser welding process, supplemented by multi-layer anti-corrosion coatings to ensure long-term maintenance-free operation in humid salt spray environments. The liquid level sensor designed for battery compartment leakage monitoring has high sensitivity and an anti-false alarm algorithm, which can promptly and accurately detect trace amounts of electrolyte or coolant leakage and issue early warnings.          The person in charge of the power station project commented: "The safety of energy storage facilities is the lifeline. We chose environmental instrument products because of their deep foundation in high-end industrial fields such as petroleum and chemicals. Their sensors can not only withstand harsh environments, but their output signals are also stable and reliable, which provides a trustworthy 'sensory nerve' for the automated safety management system of our entire power station."          This successful cooperation is no accident. The products of Environmental Instruments have already withstood long-term tests in large national enterprises that have extremely high requirements for safety instrumented systems (SIS), such as Yangzi Petrochemical and Zhenhai Refining and Chemical. The company extends the reliability developed in such high-end industrial scenarios to the new energy field, demonstrating its profound technology migration capabilities and broad market adaptability. This is not only a sales success of a single product, but also a vivid practice of the environmental instrumentation strategy of "serving emerging strategic industries with industrial-grade reliability", laying a solid foundation for the subsequent development of more high-demand new energy markets such as nuclear power and offshore wind power.

The current types of pressure transmitters are roughly divided into: resistance strain gauge pressure transmitters, semiconductor strain gauge pressure transmitters, piezoresistive pressure transmitters, inductive pressure transmitters, capacitive pressure transmitters, resonant pressure transmitters and capacitive acceleration sensors. 　The main function of the pressure transmitter is to transmit the pressure signal to the electronic device. The basic principle is: convert the mechanical signal of water pressure into a current (4-20mA)? Such an electronic signal pressure has a linear relationship with the voltage or current size, generally a proportional relationship. Therefore, the voltage or current output by the transmitter increases with the pressure. The two pressures of the measured medium of the pressure transmitter are passed into the high and low pressure chambers. The pressure in the low pressure chamber adopts atmospheric pressure or vacuum and acts on the isolation diaphragms on both sides of the δ element (ie, the sensitive element). It is transmitted to both sides of the measuring diaphragm through the isolation plate and the filling liquid in the element. The pressure transmitter is a capacitor composed of a measuring diaphragm and electrodes on both sides of the insulating sheet. ?When the pressure on both sides is inconsistent, the measuring diaphragm will be displaced, and the displacement is proportional to the pressure difference, so the capacitance on both sides is not equal. Through the oscillation and demodulation links, it is converted into a signal proportional to the pressure.   The main advantages of pressure transmitter (1). Reliable work and stable performance. (2). Special V/I integrated circuit, few peripheral components, simple and easy maintenance, small size, light weight, extremely convenient for installation and debugging. (3). Aluminum alloy die-cast shell, three-terminal isolation, electrostatic spray protective layer, strong and durable. (4) .4-20mA?DC two-wire signal transmission, strong anti-interference ability and long transmission distance. (5). LED, LCD, and pointer three indicator meters make on-site reading very convenient. Can be used to measure viscous, crystallized and corrosive media. (6). High accuracy and high stability. In addition to the imported original sensor which has been corrected by laser, the comprehensive temperature drift and non-linearity of the whole machine within the operating temperature range are precisely compensated.

Every 1% pressure fluctuation in electrode coating may lead to a 0.5% difference in final battery capacity." A process engineer from Leading Intelligence pointed out at the technology sharing meeting. On the double-layer high-speed wide-width coating machine model on display, multiple sets of integrated pressure transmitters feed back data to the central control system in real time to achieve closed-loop adjustment.       Deep decoding of cutting-edge application scenarios   At this exhibition, the application of pressure transmitters showed a trend of refinement and sceneization:       "Heart monitor" of solid-state battery mass production process   In the solid electrolyte lamination molding process, in the solution jointly demonstrated by Enjie and Honeywell, a special pressure transmitter monitors the uniform distribution of pressure in a hundreds-ton press with an accuracy higher than 0.05% FS. This is the core to ensure that the electrolyte layer is defect-free and the interface impedance is consistent.       "Precision syringe" for sodium battery electrolyte filling   In response to the challenge of higher corrosiveness of sodium battery electrolyte, Shanghai Automation Instrument has launched a new pressure transmitter sealed with perfluoroether. Its corrosion resistance level can meet thousands of hours of continuous operation, and it has become the designated choice of many electrolyte filling equipment manufacturers.       "Digital Witness" for Battery Safety Testing   In its battery abuse testing system, Germany's Dicatron synchronized a high-frequency response pressure sensor (sampling rate >1kHz) with a high-speed camera, and for the first time publicly demonstrated the millisecond-level correlation data of the pressure wave transmission inside the battery and the occurrence of thermal runaway at the moment of acupuncture, providing a new dimension of basis for safety design.       Technology evolution: smarter, more integrated, more resilient   Three major trends in pressure sensing technology presented at this exhibition:       Pre-prepared intelligent diagnosis: The Sitrans P500 series released by Siemens comes with self-checking and predictive maintenance algorithms, which can provide early warning of sensor drift or process anomalies, reducing the risk of unplanned downtime by 60%.   Wireless and edge integration: In response to the pain point of difficult wiring inside the energy storage cabinet, Weidmüller launched a micro-pressure monitoring node in the battery pack based on the ISA100 wireless standard, which is directly connected to the BMS through the wireless gateway to realize full visualization of the internal air pressure of the Pack. exhibited wide temperature range (-40℃~150℃) and anti-vibration (>5g) products, which have been used in many national-level energy storage demonstration projects in China.
