MTN/VM330D Portable Vibration Meter
- Manufacturer: Monitran
- Category: Handheld Equipment, SENSORS
Predictive maintenance management in industrial plants requires rapid diagnostic tools that allow for the assessment of vibration severity in rotating machinery without the need for complex analytical equipment. This portable meter solves this problem by providing an inspection system that complies with ISO 10816-3, enabling instant identification of whether a machine is in a satisfactory or unacceptable condition through a clear display on its color TFT screen.
This high-performance instrument integrates an adaptive amplifier that ensures maximum accuracy in acceleration, velocity, and displacement readings. Beyond standard RMS values, the unit allows for crest factor and bearing condition analysis using specific acceleration and velocity modes. Its internal memory stores up to 100 timestamped records, which can be exported via USB in CSV format for direct integration into spreadsheets and asset tracking software.
Designed for heavy-duty use in industrial environments, the device is protected by a reinforced rubber casing and powered by a rechargeable Li-ion battery with over 18 hours of runtime. It incorporates advanced features such as selectable low-pass filters and a headphone audio output that allows the technician to listen to the vibration signature of the asset, facilitating the detection of abnormal noises or bearing impacts that might otherwise go unnoticed in numerical readings.
- Automatic evaluation according to ISO 10816-3 for machine classes I to IV.
- Multivariable measurement: RMS, Peak, Peak-to-Peak and Crest Factor.
- Advanced data management with the ability to download to PC via USB.
- Integrated audio and AC output for hearing diagnosis and external analysis.
Technical Frequently Asked Questions
1. How does compliance with ISO 10816-3 help the user?
The system automatically evaluates measured vibration levels against the limits established by the standard for different types of machinery. This allows non-expert personnel to immediately determine the severity of the vibration using status indicators: Good, Satisfactory, Unsatisfactory, or Unacceptable.
2. What advantage does audio output offer in a vibration meter?
It allows you to connect headphones to listen directly to the accelerometer signal. This auditory diagnostic technique is extremely useful for identifying bearing faults (knocking, squeaking) and lubrication problems that digital algorithms sometimes mask, providing an additional layer of safety.
3. How is the stored data exported to the PC?
The integrated USB connection and included cable are used to download data from all 100 memory slots. The data is exported to an Excel-compatible CSV file, facilitating the creation of vibration histories and trend tracking for each machine in the plant.
