MEMS ac­celerom­e­ters, force and pres­sure trans­duc­ers and as­so­ci­ated elec­tron­ics, show­case the Vi­braS­cout 3D Vi­bra­tion Mea­sure­ment asure­ment Sys­tem, which in­cludes a USBB dig­i­tal di it l tri­ax­ial ac­celerom­e­ter com­bin­ing a MEMS ac­celerom­e­ter with a mi­cro­con­troller to cre­ate an in­tel­li­gent sen­sor.

WHAT I T DOES

The model 5340B2 is a unique and in­no­va­tive so­lu­tion for fast, por­ta­ble, 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, log real-time data to a de­lim­ited file for im­port­ing into Ex­cel, has auto and smart trig­ger­ing modes and dig­i­tal fil­ters to im­prove sig­nal/noise ra­tio, per­forms real-time com­pres­sion to Fast Fourier Trans­form (FFT).

Other fea­tures of the 5340B2 in­clude:

• Ap­ply post-pro­cess­ing anal­y­sis 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.

• One click ex­port of all plots and text files to data file di­rec­tory.

HOW I T WORKS

The ac­celerom­e­ter con­tains a vari­able ca­pac­i­tance ( VC) MEMS chip (200g range) with USB in­ter­face. Load the soft­ware onto your PC or lap­top (con­tact sup­plier for min­i­mum com­puter sys­tem re­quire­ments). The stan­dard USB pro­to­col han­dles all the sen­sor com­mu­ni­ca­tions with the PC; no ex­ter­nal power is re­quired for the sen­sor, sim­ply plug it in to 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.
