PC Vibration Measuring System VibroMetra

VibroMetra is a USB based system for typical vibration measuring applications.

Advantages

• The system was designed for typical tasks of vibration measurement. No ballast by unwanted functionality.
• The system is modular which makes it upgradeable and particularly economic with lower channel numbers.
• The necessary hardware is very compact which makes it particularly suited for mobile use.
• Short installation and training time. After a few minutes you may start with the first measurement.
• Off-line measurement: VibroMetra permanently saves the raw data stream of the sensor signal in the background. By this means you may analyze your measurement later again with other settings or other software instruments.
• Data export as graphics, text or binary file
  

Applications

• Vibration measurement and diagnosis at rotating machinery
• Balancing of rotating parts
• Building vibration measurement
• Human vibration measurement
• Production quality control
• Laboratory measurements
• Mobile measurements with notebook PC

Hardware

Software

Signal processing is performed by the software. It consists of independent modules similar to common hardware instruments. The following software instruments are currently available:

• VM-BAL: Balancing System
• VM-FFT: Vibration Analyzer
• VM-TRACK: Run-up / Slow-down Tracking Analyzer
• VM-SCOPE: Oscilloscope
• VM-PLOT: Y/t Plotter
• VM-REC: Data Logger
• VM-METER: General Vibration Meter
• VM-HAND: Hand-Arm Vibration Meter
• VM-BODY: Whole-Body Vibration Meter
• VM-SHIP: Vibration Meter for Ships
• VM-STRUC / VM-PERS: Building Vibration Meter

Trial Software: The latest VibroMetra version including all available software instruments can be downloaded here. The installation becomes fully operational after software registration for the desired instruments. It can also be started in the Simulator mode for testing its functions free of charge with simulated signals.

Software Registration: The latest software versions of the instruments are always available within the VibroMetra package for free downloading. So you have access to the latest updates and added functions without paying again. For using these instruments with your M302 / M312 a software key is needed. This software key can be purchased. A license belongs to one or two channels of a particular M302 with a particular serial number. The registration information is stored inside the M302 / M312. You can connect this unit to any PC - it will always keep its registered instruments. Each VibroMetra instrument can be purchased individually.

Clone Function: The software instruments feature a so-called Clone function which allows to copy an instruments with all its settings up to four times. Thus you don't need to type in all settings again if you want to change one parameter only. Cloning may be useful, for example, if you want to measure vibration acceleration, velocity and displacement simultaneously with one VM-METER instrument.

System Components

1. Piezoelectric sensors with IEPE output are directly connected to the PC by the USB converter M302 / M312. Piezoelectric sensors with charge output are connected with an in-line charge converter.
2. M302 / M312 units are connected to the USB-input of the PC. The PC supplies the M302 / M312 with energy. No external power supply is needed.
3. The instruments work on the PC-screen simultaneously. You can combine them at will.
4. Event messengers enable the instruments to transmit messages about changes of measured values or other events.

Calibration

The VibroMetra package includes a free calibration module which is useful for calibrating the entire measuring chain from the mechanical sensor input to the measuring display. By means of a vibration calibrator the sensitivity of a transducer can be determined easily. The measured sensitivity and the calibration period are stored in a data file.
