Triaxial vibration sensor and analysis software

Dytran’s 5346A2 USB powered, digital, six degrees of freedom sensor combines a three-axis MEMS accelerometer, three-axis gyroscope, and onboard temperature sensor with a microcontroller to create a smart sensor. The VibraScout 6D is a plug-and-play, cost effective, portable data acquisition system. Measure X,Y,Z acceleration, roll, pitch, yaw and temperature using a laptop or tablet.

The Dytran model 5346A2 is a unique and innovative solution for fast, portable and cost effective vibration surveys and data acquisition. Easy to install software allows for real time, three-directional vibration data acquisition (including static inclination), three-directional orientation data acquisition (gyroscope) along with real-time temperature monitoring, says the manufacturer. The system stores acceleration, gyro and temperature information, and the built-in firmware handles USB communication and provides a number of unique features including storage of device serial number and storage of accelerometer, gyro and temperature calibration data.

VibraScout 6D Software Features include: • Real-time display of acceleration, gyro and

temperature data with five seconds of buffer. • Three-channel, multi-channel, scope (rotating machinery) and real-time waterfall plots available at runtime. • Min, max, instant measurement values displayed

for all nine channels at runtime. • User selectable frequency settings for windowing

and frequency range settings. • Imperial or standard engineering units for all

channels; unit conversion is selectable by user. • Embedded post processor for data export to ASCII, UFF58, Matlab compatible. MAT and JPEG files. • Plots overlay for channel to channel comparison. • API available as .NET dll for custom application

development.

HOW IT WORKS

The accelerometer contains a variable capacitance (VC) MEMS chip (200g range) with USB interface. Load the software onto your PC or laptop. The standard USB protocol handles all the sensor communications with the PC; no external power is required for the sensor, simply plug it into the USB port. The sensor is hermetically sealed in a titanium housing weighing 13 grams, allowing it be used in harsh environments from test tracks to field monitoring. The frequency range of the VibraScout 6D accelerometer is 0 Hz (DC) to 1,100 Hz and the gyroscope is 0-250 Hz. Units can withstand 10,000g shock.

Applications for the VibraScout 6D Include: • Develop “Pass/Fail” criteria for vibration or

shock-based end-of-line acceptance testing. • Produce graphics, charts and data for reports and

white papers. • Document “before-and-after” condition to assess

effectiveness of design changes. • Perform ride quality and other whole-body

human response studies. • Complete university engineering degree

coursework and thesis papers. • Establish the basis for simplified machinery

condition monitoring programmes. • Quickly quantify and pinpoint sources of

unwanted vibration. • Measure tilt angles on heavy equipment,

construction sites, and structures. • Survey anything to get a feel for what is happening – the first step toward fixing it! Metromatics is the distributor in New Zealand for Dytran Instruments, Inc.
