Overview
The ACV12 Piezoelectric Acceleration Sensor exploits the piezoelectric effect of piezoelectric ceramics. When the sensitive core is vibrated, it generates electric charges on the material’s surface. When the vibration frequency is much lower than the sensor’s natural frequency, the amount of charge is proportional to the acceleration. By measuring the charge, the acceleration value can be obtained.
Key Features
- Self-powered Operation: Eliminates the need for external power supply, simplifying installation and reducing costs.
- Wide Frequency Range: Offers a broad frequency response from 1 to 10000Hz, making it suitable for a wide variety of vibration monitoring tasks.
- Cost-effective: Provides high performance at a reasonable price, offering excellent value for money.
- Reliable Grounding: The signal ground is connected to the housing, ensuring stable signal transmission.
Applications
- Industrial Machinery: Used for vibration monitoring in industrial equipment to detect potential failures and ensure smooth operation.
- Vehicle Monitoring: Applied in vehicles to monitor the vibration of components, helping to improve vehicle performance and safety.
