Multifeature vibration analyser

March 2002 Analytical Instrumentation & Environmental Monitoring

IOtech now offers a new full-featured vibration analyser, the portable ZonicBook. Available in 4-, 8-, or 16-channel configurations, the compact ZonicBook accepts ICP accelerometer and microphone inputs directly, and simultaneously samples all channels at 51,2 kHz with a separate Sigma Delta converter for each input channel. In addition to ICP inputs, the ZonicBook is capable of measuring standard AC and DC voltages.

Analysis capabilities include FFT analysis, integration/differentiation, averaging, octave analysis, and much more with the Windows-based eZ-Analyst software. The combination of the ZonicBook, eZ-Analyst software and a notebook computer provide a full featured, portable sound and vibration analyser.

This system can acquire continuous, gap-free data into the PC's memory and hard drive while viewing the data in time- or frequency-domain on the PC. Its makers say that the ZonicBook is unique in its ability to measure vehicle network parameters, concurrent with sound and vibration measurements. Using the optional IOtech DBK70 vehicle bus interface, the system can simultaneously acquire vehicle network parameters such as speed, RPM, engine temperature, etc, while making sound and vibration measurements directly from transducers in the vehicle. Supported vehicle networks include J1850 VPW, J1850 PWM, ISO-9141, and CAN.

The ZonicBook can be operated from 12 V d.c. battery for in-vehicle and portable sound and vibration applications, as well as AC-powered for lab applications. An optional battery/UPS option is available for over 6 hours of operation.
