Solid-state digital-multimeters are being used in multichannel automatic data-acquisition systems to determine strain values from strain-gage resistance evaluation rather than using conventional Wheatstone bridge. Both the direct-resistance method and the reverse current one are examined in two tests. Each one lasted for two weeks. Irrelevant differences were observed between the two methods in spite of the adopted general-purpose low-cost switch-control unit.

Abstract
Solid-state digital-multimeters are being used in multichannel automatic data-acquisition systems to determine strain values from strain-gage resistance evaluation rather than using conventional Wheatstone bridge. Both the direct-resistance method and the reverse current one are examined in two tests. Each one lasted for two weeks. Irrelevant differences were observed between the two methods in spite of the adopted general-purpose low-cost switch-control unit.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
