BARS - Bay Acquisition & Recording System

Smaller, Lighter, Faster and Best Value For Money was the request.

BARS is a solution for both low, mid and high channel count data acquisition, importantly our offer is at a purchase and through life price that every user can afford.

Exceptional Quality
Very high performance 24 Bit Analogue to digital and digital to analogue conversionHigh quality branded micro-PC with genuine daylight readable 1024 x 600 screen Easy to use recording software designed for the small screen size Ruggedly packaged in strong, military grade leather cases to protect the micro PC and acquisition system.

  • BARS Micro System
  • 24 bit ADC
  • Parallel sample and hold
  • IEPE 4ma transducer power
  • Anti-alias protection
  • AC/DC coupling
  • Tachometer input
  • Trigger input
  • Analogue output

Channel counts from 4 to 32 and a card configuration to suite most applications.

BARS is a battery powered, ultra portable data recording system that lets you inspect and analyse your data whilst in the field.
It is the natural successor to the instrumentation tape recorder, with more storage space and channels while costing less.
All of the post processing and specialist modules work both with the BARS micro-system and larger format USB II connected systems. For customers who have Sony EX systems the BARS system will integrate with the Sony PCscanIV post processing software.

Sample rates on all channels up to 225,000 samples per second per channel written to disk on a standard note book PC.

The slowest system samples at 52kHz per channel – fast enough for all NVH work. All cards sample at many lower rates to suite all applications and conserve disk space.
