Miniature Pressure Sensor

Overview of Miniature Pressure Sensor

The Miniature Pressure Sensor series is the ultimate solution for "in-situ" pressure measurement where size constraints and dynamic response are critical.

• What is it? It is a micro-sized pressure transducer that uses micro-machined silicon diaphragms to sense pressure changes. Designed to be "ultra-thin" and "ultra-small," it can be embedded directly into surfaces or placed within a flow field without disrupting the natural flow characteristics. This allows for the accurate capture of rapid pressure fluctuations that larger, traditional sensors would miss.

• Principles of Operation Based on the piezoresistive effect, the sensor incorporates a high-precision integrated silicon element. When pressure is applied, the silicon diaphragm deforms, causing a change in resistance that is converted into a proportional electrical signal. The "silicon-on-silicon" structure ensures excellent thermal stability and a high natural frequency.

• Main Application Field: These sensors are primarily used in high-tech research environments, including wind tunnel testing, aerodynamic studies of aircraft and engines, fluid mechanics, and underwater weaponry trials. They are also vital in biomedical research and shockwave measurement (chemical or nuclear blasts).

• Key Characteristics The series is defined by its incredibly small physical footprint—the smallest version measures only 2.54mm in diameter and 3.77mm in length. Despite the size, they boast a massive frequency range (up to 2MHz), high accuracy (0.1% FS), and the ability to withstand extreme temperatures from -40°C to +175°C.

Features of Miniature Pressure Sensor

1. Ultra-Miniature Footprint: Minimum diameter of 2.54mm allows for installation in extremely tight spaces and on curved surfaces.

2. Superior Dynamic Response: High natural frequency (up to 2MHz) enables the capture of high-speed pressure transients and shockwaves.

3. Minimal Flow Interference: The ultra-thin profile ensures that measurements are taken without disturbing the boundary layer or flow field.

4. High Accuracy & Stability: Precision piezoresistive elements provide accuracy up to 0.1% FS with excellent long-term stability (±0.1% FS/year).

5. Wide Pressure & Temp Range: Measurement ranges from -100KPa to 60MPa, with operational capability in temperatures up to 175°C.

6. Rugged Construction: Encased in 1Cr18Ni9Ti stainless steel with IP67 protection, making it resistant to harsh environments and extreme vibrations (up to 100g).

Applications of Miniature Pressure Sensor

• Aerodynamics & Wind Tunnels: Measuring surface pressure distributions on scale models of aircraft and vehicles.

• Engine Testing: Monitoring pulsating pressures in intake manifolds and turbine stages.

• Fluid Mechanics: Studying turbulence and boundary layer behavior in hydraulic and pneumatic systems.

• Biomedical Engineering: In-vivo pressure monitoring and medical device R&D.

• Blast & Shockwave Research: Capturing the rapid pressure rise of explosions and aerodynamic shock fronts.
