MTN/VM220 Portable Vibration Meter
- Manufacturer: Monitran
- Category: Handheld Equipment, SENSORS
Rapid verification of the health status of rotating machinery is essential to prevent unexpected downtime and optimize predictive maintenance. The MTN/VM220 portable vibration meter provides a compact, high-precision solution for monitoring pumps, motors, and fans, enabling instant assessment of vibration severity according to the limits established by the international standard ISO 10816-3 via an intuitive color visual interface.
This portable instrument stands out for its versatility, allowing measurements of acceleration (up to 20g), velocity (200 mm/s), and displacement (2000 µm). It incorporates specific modes for detecting bearing faults, evaluating the crest factor and vibration signature to identify incipient wear before it becomes a critical failure. Its adaptive amplifier guarantees exceptional linearity across the entire measurement range, ensuring reliable data for technical decision-making on the factory floor.
Designed to withstand daily use in demanding industrial environments, the MTN/VM220 features a reinforced rubber housing that protects it against impacts and accidental drops. Its long-life Li-ion battery provides over 20 hours of continuous operation, enabling full days of inspection without recharging. It also includes a headphone audio output that allows technicians to directly listen to the acoustic signature of the asset, a highly effective auditory diagnostic technique for locating abnormal mechanical noises.
- Integrated ISO 10816-3 Assessment for an immediate interpretation of the risk.
- Measurement of multiple parameters: RMS, Peak, Peak-to-Peak and Crest Factor.
- Internal storage of 100 data points with date and time for trend tracking.
- Complete inspection kit with carrying case, magnetic base and probe.
Technical Frequently Asked Questions
1. How does the MTN/VM220 differ from the VM330D model?
The MTN/VM220 is the portability- and ease-of-use optimized version, ideal for operators requiring a quick "pass/fail" diagnostic according to ISO standards. While it doesn't offer the advanced data export or spectrum analysis of the 330D, its battery life is longer and its interface is simpler for large-scale inspection rounds.
2. Is it necessary to calibrate the supplied external sensor?
The equipment is supplied as a factory-calibrated unit (Meter + MTN/2200 Probe). To maintain the nominal accuracy of ±5%, annual verification of the unit is recommended. The sensor uses a 4-pin Lumberg industrial connector, ensuring interference-free signal transmission.
3. How does the audio output for diagnostics work?
By connecting standard 3.5mm headphones, the user can listen to the sensor's raw signal. This allows for the detection of faults such as lack of lubrication, metal-to-metal contact, or impacts on bearings, which, while not drastically increasing the RMS value, produce a characteristic sound signature that an experienced technician can easily identify.
