Dytran 5340B2 for simplified vibration testing

The VibraScout 3D vibration measurement system from Dytran Instruments,
Inc. features a USB digital triaxial accelerometer combining a MEMS
accelerometer with a microcontroller to create an intelligent sensor. Dytran is
a leading manufacturer of piezoelectric and DC MEMS accelerometers, force and
pressure transducers and associated electronics.

VibraScout’s Model 5340B2 is an 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) along with real-time temperature monitoring. The
system will store acceleration and temperature information, display real-time
scrolling plots of acceleration data in Min, Max and Mean, and log real-time
data to a delimited file for importing into Excel. Additionally, the vibration
measurement system has auto and smart triggering modes and digital filters to improve
signal/noise ratio, and also performs real-time compression to Fast Fourier
Transform (FFT).

Key features of Model 5340B2 3D vibration measurement system include post-processing
analysis applied to record data from VibraScout sensor; test log to display
RMS, Max, Min, and pk-pk plots for overall recorded data; ‘Scope Preview’
feature for data playback; single and double integration for velocity and
displacement calculation; user defined filters for each individual channel; FFT
and octave analysis; multi-channel overlays; and one-click export of all plots
and text files to data file directory.

The accelerometer contains a variable capacitance (VC) MEMS chip (200g
range) with USB interface. Once the software is loaded onto the PC or laptop, the
standard USB protocol handles all the sensor communications with the PC, with
no external power required for the sensor, which is simply plugged into the USB
port. The sensor is hermetically sealed in a titanium housing weighing just 17
grams, allowing it to be used in harsh environments from test tracks to field
monitoring. The frequency range of the VibraScout is 0 Hz (DC) to 1,100 Hz.
Units can withstand 10,000g shock.

The Model 5340B2 system consists of: Model 7543B2, USB powered triaxial
accelerometer, 200g; Model 6330A15, 15-foot cable assembly, 4-pin to USB; Model
6247A1 mounting screws (6-32); Model 6688 mounting screws (M3); and Model 9008
Software Toolkit.

Applications of VibraScout 3D vibration measurement system: Develop ‘Pass/Fail’
criteria for vibration or shock-based ‘end of line’ acceptance testing; Product
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 a simplified
machinery condition monitoring program; Quickly quantify and pinpoint sources
of unwanted vibration; Measure tilt angles on heavy equipment, construction
sites, and structures.
