Type9257B

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

•Universalapplicable

•Forcuttingforcemeasurements

•Stableandreliable

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.
