Pressure Sensors, Transducers

1. Overview

Pressure sensors and transducers are devices that convert mechanical pressure signals into electrical outputs. They serve as critical components in monitoring and controlling pressure in various systems. Modern industrial automation, medical diagnostics, and automotive safety systems rely on their precise measurements to ensure operational efficiency and safety.

2. Main Types and Functional Classification

TypeFunctional CharacteristicsApplication Examples
Strain GaugeHigh accuracy, stable output, requires bridge circuitIndustrial machinery, load cells
PiezoresistiveMiniaturized design, high sensitivity, temperature-dependentMedical blood pressure monitors
CapacitiveLow power consumption, corrosion-resistant, nonlinear outputAerospace altitude sensors
PiezoelectricSelf-generating, dynamic pressure measurementEngine combustion analysis
Optical FiberImmune to EMI, suitable for harsh environmentsOil well downhole monitoring

3. Structure and Components

Typical components include:

  • Pressure port (stainless steel/ceramic diaphragm)
  • Sensing element (MEMS silicon chip, strain gauge)
  • Signal conditioning circuit (amplifier, ADC)
  • Output interface (4-20mA, I2C, CANbus)
  • Environmental sealing (IP67 rating standard)

4. Key Technical Specifications
