Vacuum pressure sensors are intelligent tools capable of automatic precise measurement and real-time monitoring, with increasingly widespread applications across various industrial sectors. As a professional vacuum pressure sensor manufacturer in Beijing, Kunlun Zhongda integrates R&D, production, sales, and logistics to provide comprehensive vacuum pressure solutions with advanced manufacturing processes, reliable product quality, competitive pricing, and efficient delivery services.
Core Technical Principle
Beijing vacuum pressure sensors employ advanced micro-machining technology and the piezoresistive effect principle. The working mechanism involves medium pressure acting directly on the sensor's stainless steel diaphragm, causing micro-displacement proportional to the medium pressure. This changes the sensor's resistance value, which is detected by high-precision electronic circuits and converted into standard signals (such as 4-20mA, 0-10V, or RS485 digital signals).
Main Technical Parameters
• Measurement Range: -100kPa～0kPa (vacuum), 0～100MPa (pressure)
• Accuracy Class: ±0.5% FS (typical), ±0.25% FS (high-precision models)
• Overload Capacity: 150% FS
• Stability: ±0.1% FS/year
• Response Time: <10ms
• Operating Temperature: -40℃～125℃
• Power Supply: 12～36V DC
• Output Signals: 4-20mA/0-10V/0-5V/RS485 (Modbus protocol)
• Protection Rating: IP67 (dustproof and waterproof)
• Process Connection: G1/4, G1/2, NPT1/2 international standard interfaces
• Diaphragm Material: 316L stainless steel, Hastelloy, tantalum alloy (optional)
Application Fields
• Petroleum Pipelines: Pipeline pressure monitoring, leak detection
• Water Conservancy and Hydropower: Water pump pressure monitoring, water level measurement
• Rail Transportation: Braking system pressure control
• Intelligent Buildings: Central air conditioning system monitoring
• Industrial Automation: Process control, equipment protection
• Military Equipment: Aerospace pressure measurement
• Petrochemical Industry: Reactor pressure control
• Power Energy: Boiler pressure monitoring
• Shipbuilding: Cabin pressure monitoring
• Machine Tools: Hydraulic system pressure control

Application Cases and Data
• In a major West-East Gas Pipeline project, over 2,000 units of our high-pressure sensors (range 0-60MPa) were deployed. They have been operating continuously for over 36 months with an average accuracy deviation of less than ±0.2% FS, significantly enhancing pipeline safety and leak detection capabilities.
• For a leading automotive brake system manufacturer, we supplied 50,000 vacuum sensors for brake boosters. The products achieved a 99.97% on-line pass rate and reduced the system failure rate by 32% compared to previous solutions.
• In a chemical plant’s reactor pressure monitoring application, 120 units of our corrosion-resistant sensors (Hastelloy diaphragm) have withstood highly corrosive environments for 24 months without a single failure, ensuring continuous production safety.
• A municipal water supply company adopted our pressure sensors for city-wide pipe network monitoring. Over 5,000 sensors helped reduce water leakage by 18% annually and cut energy consumption by 15% through optimized pump control.
• In semiconductor manufacturing, our high-vacuum sensors (-100kPa to 0kPa) achieved stability of ±0.05% FS under continuous 24/7 operation, meeting the extreme requirements of cleanroom environments.
