VPS21-A002 Triaxial Vibration Sensor
The VPS21-A002 triaxial vibration sensor is designed to measure vibration along three mutually perpendicular axes: horizontal, vertical, and axial, using three integrated sensing elements housed within a single enclosure. By capturing a complete range of dynamic vibration data from a single mounting location, this sensor enhances data acquisition speed, ensures measurement consistency, and reduces installation, wiring, and maintenance costs.
Engineered for monitoring mechanical vibrations in confined spaces, the sensor features epoxy resin sealing and a durable integrated cable, ensuring a secure connection and reliable data transmission even in demanding environments.
- Three-axis vibration measurement (A, B, and C directions) with a range of -2g to 2g (customizable up to -6g to 6g)
- Integrated three-sensor system (accelerometer, 0.05–100 Hz)
- Supports independent monitoring of single or multiple frequency bands (up to 12) per measurement channel
- Capable of measuring RMS values, maximum values, peak values, and peak-to-peak values
- Three independent 4-20mA industrial-standard outputs for seamless integration with control systems
- Two programmable alarm relays with set/break functions and an additional system fault relay
- Each alarm relay has individually programmable thresholds and delay settings.
- Built to withstand extreme temperature, humidity, pollution, salt mist, and electrical noise interference
- Supports customizable communication protocols, output formats, and alarm conditions based on user requirements
- RS-485 communication enables fast and efficient data transmission to other modules
The VPS21-A002 triaxial vibration sensor is used for monitoring low-frequency structural vibrations, providing real-time vibration status data to prevent potential system damage. Key applications include:
