瑞士奇石乐Kistler9257B三向测力仪

Type9257B
 
Quartz  three-component  dynamometer for  measuring  the three  orthogonal componentsofaforce. Thedynamometer hasagreatrigidity andconsequentlyahighnaturalfrequency. Itshigh  resolution  enables  the  smallest dynamic  changes  in largeforcestobemeasured.

Description
The dynamometerconsists  of  four  three-componentforce sensors  fitted  under  high  preload  betweenabaseplate and atopplate. Eachsensorcontains three  pairsofquartz  plates, onesensitivetopressure inthezdirectionandtheother two responding toshearin thex andy directionsrespectively.The forcecomponents aremeasuredpracticallywithout  displace- ment.
Theoutputsofthe  fourbuilt-inforcesensors areconnected insidethe  dynamometerinaway to  allowmulticomponent measurementsofforcesand momentstobeperformed. The eight  outputsignalsare available at the  9-conductor flange socket.
The  four  sensors  are  mounted ground-insulated.Therefore ground  loopproblemsarelargelyeliminated.
Thedynamometerisrustproof  andprotectedagainstpenetra- tionofsplashwaterandcoolingagents.Togetherwiththecon- nectingcableType1687B5/1689B5andType1677A5/1679A5 itcorrespondstotheprotectionclassIP67.
Aspecial thermal  isolation  coating  isintegratedinthe  top plate  which  renders  the  dynamometerlargely insensitive  to temperatureinfluences.
