Pressure transmitters&and sensors come in many types; classifying them by their working principle (sensing technology) is the most essential approach. The following are the main types of pressure sensors and their characteristics:

Type Core principle Main advantages Typical application scenarios
Piezoresistive resistance change (piezoresistive effect) high accuracy, high sensitivity, fast response, small size, low cost most widespread: industry, automotive, medical, consumer electronics
Capacitive capacitance change low power consumption, good temperature stability, high sensitivity, strong overload capability low pressure, differential pressure, liquid level, medical respiratory equipment
Piezoelectric charge generation (piezoelectric effect) extremely fast response, rugged, wide temperature range dynamic pressure, impact, explosion, engines, acoustics
Strain gauge resistance change (strain effect) mature and reliable, wide measurement range, strong output industrial weighing, hydraulic/pneumatic, structural testing
Resonant frequency change extremely high accuracy, extremely high resolution, long-term stability, digital output precision laboratories, aerospace, high-end industry
Optical change in optical properties immune to electromagnetic interference, intrinsically safe, corrosion-resistant, distributed oil wells, electric power, aerospace structures, strong EMI
MEMS mostly piezoresistive/capacitive miniaturization, low power consumption, low cost, high integration, mass production consumer electronics, automotive tire pressure, medical catheters, IoT

Which type of pressure sensor to choose depends on the specific application requirements, including measurement range, accuracy requirements, working environment (temperature, medium, electromagnetic interference), response speed, output signal requirements, size constraints and cost budget, etc. Piezoresistive types (especially MEMS) are the mainstream in the current market due to their comprehensive advantages, but in specific occasions requiring extremely high precision, EMI resistance, intrinsic safety or ultra-fast response, other types are indispensable.
