Overview
The ACI16 is an Integrated Electronics Piezoelectric (IEPE) sensor capable of simultaneously measuring vibration signals in three directions. With stable performance, it is suitable for long-term vibration monitoring, outputting voltage signals that change according to the vibration state.
Key Features
- Triaxial Measurement: The ability to measure vibration signals in the X, Y, and Z directions simultaneously provides a more comprehensive understanding of the vibration state of the monitored object. This is particularly useful in industrial equipment testing and structural analysis.
- IEPE Three-wire Output: The three-wire IEPE voltage output simplifies the connection to data acquisition systems and helps in reducing signal interference. It enables efficient transmission of the measured signals.
- Proper Grounding: Connecting the signal ground to the housing helps in stabilizing the electrical potential and reducing electrical noise, ensuring more accurate measurement results.
- Metal Welded Package: The metal welded package offers excellent protection against external mechanical impacts, moisture, and dust. With an IP65 waterproof rating, the sensor can operate reliably in harsh environments.
- Lightweight Design: Weighing only 48g, the sensor can be easily installed on various objects without adding significant additional load, making it suitable for a wide range of applications.
Applications
- Industrial Equipment Triaxial Testing: Used to monitor the vibration of industrial machinery from multiple directions. This helps in detecting potential issues such as misalignment, unbalance, or bearing failures more accurately, enabling timely maintenance and preventing unexpected breakdowns.
- Experimental Testing: In research and development laboratories, the ACI16 sensor can be used for triaxial vibration testing of prototypes, components, or materials. It provides valuable data for analyzing the dynamic behavior and performance under different vibration conditions.
