Piezo Ceramic Sensor are high-precision sensing elements based on the piezoelectric effect. They utilize the characteristic of specific ceramic materials (such as PZT lead zirconate titanate series) to generate electrical signals when subjected to mechanical stress, enabling precise measurement and conversion of physical quantities such as pressure, vibration, and acceleration.
Excellent Mechanical Properties Piezo Ceramic Sensor for Industrial Equipment
Product Description
Ceramic Sensor use PZT ceramic as their core material, relying on the piezoelectric effect to achieve bidirectional conversion between mechanical and electrical energy. With advantages such as high sensitivity, fast response, and resistance to harsh working conditions, they are widely used in vibration, pressure, and shock detection scenarios in industrial automation, automotive electronics, medical equipment, and aerospace. Different formulations of piezoelectric ceramics (such as PZT-4/5H/8) exhibit significant performance differences. Hard ceramics are suitable for high-power, high-stability applications, while soft ceramics focus on high-sensitivity detection. High-power ceramics are suitable for strong impact/high-power ultrasonic applications. Their customized structural forms (discs, tubes, rings, etc.) and packaging solutions can meet the installation and operating condition requirements of different industries, making them one of the core components in the industrial sensing field.
Core working principle
Piezoelectric Ceramic Sensors operate based on the direct piezoelectric effect: when an external mechanical force (pressure, vibration, or acceleration) is applied to the piezoelectric ceramic element, polarization occurs within the material, and a charge proportional to the external force forms on the crystal surface. A high-impedance charge amplifier or voltage amplifier converts the weak charge signal into a standard voltage signal output, achieving high-fidelity conversion from a non-electrical physical quantity to an electrical signal.
Q = d⋅F where Q is the output charge, d is the piezoelectric constant, and F is the applied external force.
