Product Details
High performance piezoelectric accelerometer for PCB in the United States740A02Our Advantages：PCB Piezotronics, as a piezoelectric sensor manufacturer, is known for its high reliability, wide frequency response characteristics, and environmental adaptability in its products. among which,PCB 740A02It is a piezoelectric accelerometer widely used for dynamic vibration and impact measurement. Although "740A02" was not directly mentioned in the search results, through cross comparison of its series models (such as 740B02) and related technical documents,
High performance piezoelectric accelerometer for PCB in the United States740A02 provides various product information services:Core performance characteristics
1. High sensitivity and wide dynamic range
Using high-performance piezoelectric crystal materials, it responds sensitively to small vibration signals and can detect acceleration changes as low as 0.001g.
Supports full range measurement from slight vibration to high-intensity impact, suitable for laboratory research and on-site monitoring.
2. Excellent stability and anti-interference ability
Internally integrated signal conditioning circuit (IEPE design), with strong anti electromagnetic interference capability for output signals, suitable for complex industrial environments.
Low drift design ensures data consistency for long-term continuous monitoring.
3. Durable and sturdy, with strong environmental adaptability
Stainless steel shell, with good waterproof, dustproof, and anti-corrosion performance (IP67 or above).
It can operate stably under harsh conditions such as high temperature, high humidity, and strong electromagnetic interference.
4. Easy to install and integrate with the system
Standard M5 or 1/4-28 threaded installation interface, supporting multiple fixing methods such as magnetic seat, adhesive, screw, etc.
The cable adopts a shielded design and comes with an aviation plug as standard, making it easy to connect with the data acquisition instrument and vibration analysis system.
5. Factory calibration and traceability
Each sensor comes withFactory calibration reportProvide key parameters such as sensitivity, frequency response, and phase characteristics.
Compliant with ISO/IEC 17025 standard, supporting metrological traceability, suitable for testing scenarios that require certification.
Typical application areas
Mechanical equipment status monitoringVibration trend analysis and fault warning of rotating machinery (fans, pumps, compressors). Early damage identification of bearings and gearboxes.
Impact and Drop TestingProduct transportation safety assessment. Verification of impact resistance performance of consumer electronics and devices.
Structural Dynamics TestingModal analysis of bridges, buildings, and tower structures. Seismic response simulation and seismic performance evaluation.
Automobiles and Rail TransitVehicle NVH (noise, vibration, and acoustic roughness) testing. Dynamic response measurement of suspension system.
Aerospace and DefenseEngine vibration monitoring. Load measurement during rocket launch process.
Precautions for use
Avoid using beyond the rangeInstantaneous impact exceeding acceleration may cause sensor damage.
correct installationEnsure that the installation surface is flat and clean, and that the tightening torque meets the specifications (generally 1.5-2.0 N · m) to prevent looseness from affecting the frequency response.
Cable protectionTo avoid cable bending and compression, it is recommended to use armored cables for mobile or high-risk environments.
Regular calibrationIt is recommended to recalibrate every 12 months to ensure measurement accuracy.
Not applicable for static measurementPiezoelectric sensors cannot measure constant acceleration (such as gravity) and are only suitable for dynamic signal acquisition.
