The resultant signal from the combination of the normal output from the load cell and the output from the accelerometer compensates for errors introduced by the mass of the moving grip used to grip the specimen in the apparatus.Field of SearchDYNAMOMETERSElectromagnetic Specified load or strain transmission device from specimen to electrical detector Plural sensors at single location (e.g., diverse orientation, plural level) Coupling circuit for specific additional purpose (e.g., noise suppression) or having specified structure SPECIMEN STRESS OR STRAIN, OR TESTING BY STRESS OR STRAIN APPLICATION Machine tool | |
