Medical monitoring system SiSMoS-4

portable

The SiSMoS-4 provides a PC-based, fast, four-channel, 24-bit data acquisition system with data-logger and spectrum analyzer for Bartington Instruments fluxgate sensors and industry standard ICP accelerometers. Applications include environmental monitoring (of EMI and vibration) for pre-installation surveys for MRI systems, electron microscopes and similar sensitive equipments. The SiSMoS-4 performs data acquisition in three channels for a triaxial sensor fluxgate or a one channel for a uniaxial accelerometers and produces both time domain and frequency domain plots showing either slow or fast trends for magnetic and vibration data in three axes. The conversion of time-varying information into a frequency spectrum is accomplished using Fast Fourier Transforms referred to as FFT in the text. When used as a data-logger, time-stamped data can be logged (for extended periods) then retrieved and post-processed in both time and frequency domain. The system is software controlled and connection to the user’s PC is via a USB interface. Prior to data acquisition, system configuration is accomplished using the SiSMoS-4 software (Device configurationDevice configurationDevice configuration). Additional functions provided by the SiSMoS-4 system include: Selectable plot of time or frequency data Data post-processing (selectable filtering and averaging) Availability of cursors and markers for effective measurements Exports the graph data to excel file or to the clipboard in a tab-delimited format, which is accepted by most spreadsheet applications Saving of plots (images) in .bmp, .eps and .emf formats for use in reports
