Device Features:
Dytran model 7543A is a unique and innovative solution for fast and cost effective data acquisition. The only addition that is required Supplied Accessories:
is a personal computer and it is ready to take data. Model 7543A is USB powered, so no additional external power supply is required. 1) Accredited calibration certificate (ISO 17025)
The software package supplied with each sensor allows for real time, three directional acceleration acquisition along with 2) Mounting screw model 6935, qty 2
temperature data and pitch/roll data. The standard USB protocol handles all the sensor communications with the PC and provides the
following information: storage of the acceleration and temperature information, storage of pitch/roll data, real-time scrolling plots of Notes:
acceleration data with display of min, max, mean, real-time logging of data to delimited file for importing into spreadsheet, both auto [1] Over the rated Temperature Ramp Rate .
and smart triggering modes, digital filters to improve signal/noise ratio, real-time data compression to FFT, and many more. [2] Mates with Dytran cable assembly 6330AXX ("XX = Length in FT)
[3] Accelerometer bandwidth is 1.1KHz. Data can be reconstructed using the VibraScout Post Processor
Software using the Whittaker-Shannon Interpolation method.
