VibraAS - Complet Set for Vibrational Analysis

VibraAS Complete Set consists of:

• VibraAS Control Unit

Power and control unit serves as necessary interfaces for various VibraAS instruments used for experiments in the field of sound and vibrations. The unit contains analog-to-digital converter and it provides power supply for particular modules, as well. Modular concept of VibraAS set, where the control unit works as a central hub, let the users to modulate the set according to their preference and convenience. Users just pick the experiment they want to perform and plug appropriate module to PCU. PCU and all modules are sold separately, but there is also possibility to order full VibraAS package.

• VibraAS Kundt´s Tube

Kundt´s tube is used to determine the parameters of vibrations of sound within the tube. Due to movable piston and microphone, along with a generator of sound waves, the tube offers the possibility to measure the parameters of standing waves. The software analyzes and processes the data to determine the vibration of sound inside the tube. The signals are recorded and processed digitally. Bundled software can analyze the measured data from vibration sensors and export either raw data or simplified image bitmap. The software also includes functions for calculating the spectrum of measured vibrations. NOTE: For proper functionality the control unit is necessary device. Software is included. Kundt tube is a suitable tool for:

- determining sound speed in tube

- propagation of sound waves

- frequency of sound waves

• VibraAS Laser Vibrometer

The Laser vibrometer is used for non-contact vibration measurements of solid objects. The laser beam is projected onto the surface of the measured object (tuning fork, DC motor, etc.) at an approximate angle of 45 °. The position of the laser spot is then recorded by sensitive optoelectronic sensor. Software processes and visualizes the measured data and offers the tools for advanced analysis, including spectral analysis. The software features allow students to determine determinate deflections, character of vibrations or dominant frequencies of vibrations. Bundled software can analyze the measured data from vibration sensors and export either raw data or simplified image bitmap. The software also includes functions for calculating the spectrum of measured vibrations. NOTE: For proper functionality the control unit is necessary device. Software is included. The Vibrometer is primarily inteneded for school demonstrations (rather slow, demonstrative movements). The parameters of the vibrometer are as following: Measurement range - 30 mm Resolution - 20 um Sampling rate up to 6kHz usable (max 12kHz) Laser vibrometer is a suitable tool for the detection of:

- determinate deflections

- character of vibrations

- dominant frequencies of vibrations

• VibraAS Accelerometer

The Accelerometer extends the VibraAS possibilities to contact vibration measurements. With the accessory the VibraAS is able to measure vibrations on machines, oscillators, motors or any another source of vibrations in laboratory environment. Students can obtain valuable experience with measurement of vibrations and learn basic work principles with regard to accelerometers. Bundled software can analyze the measured data from vibration sensors and export either raw data or simplified image bitmap. The software also includes functions for calculating the spectrum of measured vibrations. NOTE: For proper functionality the control unit is necessary device. Software is included. The accelerometer is a suitable tool for the detection of: :

- determinate deflections

- character of vibrations

- dominant frequencies of mechanical oscillators

- determining stiffness of spring
