VM-6370T Vibration Tachometer Meter
Professional piezoelectric sensor instrument for measuring RPM (r/min), frequency (Hz), and vibration in rotating machinery. Combines photo tachometer and contact tachometer functionality in one versatile device.
Applications
Used for measuring periodic motion to detect imbalance and deflection in moving machinery. Specifically designed for on-site vibration measurement of rotating equipment, providing essential data for quality control, runtime monitoring, and predictive maintenance.
Key Features
- Compliant with ISO 2954 for periodic measurements and mechanical fault detection
- Dual functionality: combines Photo Tachometer & Contact Tachometer
- Measures rotation rate (RPM/r/min) and frequency (Hz)
- Wide frequency range: 10Hz~10kHz in acceleration mode
- Optional headphones for use as electronic stethoscope
- USB data output for PC connectivity
- Bluetooth data output option available
