Industry In-depth Article 2026: Development Status, Technical Iteration and Domestic Substitution Trend of Pressure Sensors and Pressure Transmitters

I. Industry Overview: Two Products Form a Complete Industrial Pressure Measurement System

1. Pressure Sensor: The core pressure-sensing chip, only completing the conversion from pressure to original millivolt/resistance signals without standardized signal processing. It features compact size, mostly used for embedded OEM, dynamic testing and close-range built-in equipment detection.
2. Pressure Transmitter: Built around pressure sensors, integrated with amplifying circuits, temperature compensation, linear correction and isolation circuits. It outputs standard industrial signals including 4-20mA, HART and RS485 digital signals, equipped with metal explosion-proof housings and standardized waterproof connectors. Suitable for long-distance wiring, harsh industrial sites and centralized control systems of PLC/DCS, it is standard instrumentation for process factories.

II. Global Market Scale & Demand Structure 2026 (Authoritative Industrial Data)

1. The overall global market of pressure sensors and transmitters reached USD 7.82 billion in 2025, projected to exceed USD 8.3 billion in 2026 with an average annual growth rate of 6.5%. Among them, the industrial transmitter segment recorded a market size of USD 3.32 billion, with a CAGR of 3.38% from 2026 to 2031.
2. China is the world’s largest production and consumption market. Its domestic market scale surpassed RMB 12 billion in 2025, accounting for 32% of the global total and growing 1.4 percentage points faster than the global average. High-precision transmitters (accuracy ≤0.075%FS) have risen to 35% of the market share, the fastest-growing subdivision.
3. Four core tracks drive market demand: new energy (lithium battery, photovoltaic energy storage, hydrogen energy), petrochemical industry, thermal power & new power, municipal water treatment. The penetration rate of wireless intelligent multi-variable transmitters has exceeded 55%, gradually replacing traditional analog transmitters.

Terminal Industry Demand Breakdown

• Oil & Petrochemical Industry: 31% market share, dominated by high-temperature explosion-proof and corrosion-resistant differential pressure transmitters for wellheads, reactors and pipeline safety monitoring.
• Lithium Battery & Hydrogen New Energy: Highest growth rate (14% year-on-year), matched with miniature MEMS pressure sensors and compact hygienic transmitters.
• Water Supply & Environmental Protection: 18% market share, large quantities of general pressure transmitters deployed for pipeline leakage detection and pump station constant pressure control.
• High-end Manufacturing & Semiconductors: High-precision ceramic/silicon resonant sensors for precise measurement of vacuum and micro-pressure.

III. Core Technical Iteration Trends (2026 Hot Industrial Technologies)

1. Dual Upgrade of Sensing Chip Technology

• MEMS Miniature Sensors: Continuous reduction in mass production cost, miniaturization and low power consumption for embedded installation in vehicles and energy storage equipment. Fiber-optic pressure sensors are gradually applied to high-end vacuum and strong electromagnetic interference scenarios.
• Silicon Resonant Intelligent Chips: New-generation high-precision chips promoted by Yokogawa, domestic Chuanyi and Supcon reduce long-term zero drift by 60% and extend calibration cycles to 24 months, greatly cutting factory operation and maintenance costs.

2. Intelligence & Wireless Connection Become Standard for Transmitters

1. HART/WirelessHART digital protocols for remote parameter adjustment and self-diagnosis of faults;
2. Integrated multi-variable measurement: single transmitters simultaneously measure pressure, temperature and differential pressure to replace multiple instruments and lower field wiring costs;

V. Industry Pain Points & Development Opportunities

Industry Pain Points

1. Severe homogenization in low-end market: numerous manufacturers only assemble outsourced chips without self-developed sensitive elements, triggering price wars and shrinking profit margins.
2. Bottlenecks in high-end segments: ultra-high-precision sensing chips, industrial special ASICs and core explosion-proof certification technologies are monopolized by Emerson, Yokogawa and Siemens.
3. Rising customized demands across industries: long delivery cycles for small-batch non-standard products, insufficient flexible production capacity among small and medium manufacturers.

Long-term Development Opportunities

1. Policy support for new industrialization: Intelligent manufacturing plans during the 15th Five-Year Plan, petrochemical industry upgrading and urban pipeline reconstruction continuously generate purchasing demands for millions of measuring instruments.
2. Blue ocean incremental market in new energy: Explosive demands for miniature, hygienic and explosion-proof pressure measuring equipment from hydrogen energy storage & transportation, lithium battery production lines and energy storage liquid cooling systems.
3. Huge stock replacement market: Massive instrumentation equipment commissioned before 2010 in domestic factories has entered replacement cycles, with broad room for intelligent transmitters to replace traditional analog devices.
4. Expanding overseas market: Accelerated industrial infrastructure construction in Southeast Asia, the Middle East and Latin America. Domestic transmitters gradually replace imported European and American brands with cost-performance advantages.

VI. 5-Year Industry Forecast (2026–2030)

1. Product Level: Integrated sensing & transmission products will become mainstream, blurring the boundary between sensors and transmitters. Wireless, multi-parameter and self-calibrating intelligent instruments will account for over 80% of the market.
2. Competition Pattern: Leading domestic enterprises (Chuanyi, Supcon, KLZD, etc.) continuously break through high-precision segments, while market shares of foreign brands shrink year by year. Small manufacturers without independent R&D capacity in low-end markets will exit the industry rapidly.
3. Technical Direction: Fiber-optic pressure sensing, low-temperature superconducting micro-pressure measurement and built-in AI fault prediction will become core competitiveness of high-end products.
4. Market Scale: China’s pressure sensor and transmitter market is expected to exceed RMB 20 billion by 2030, with the domestic substitution rate rising above 85%.
