Metrological characteristics
Linearity including hysteresis
Linearity represents the maximum deviation/error between ideal and actual output signal characteristics in relation to the measurand in a specific measuring range. It is expressed in percentage of the range of measurement signal (Full Scale Output).

Questo Sensore di forza-coppia a 6 assi misura tutte le forze e i momenti corrispondenti sui tre assi ortogonali. Tutte le forze e i momenti vengono acquisiti come segnali fisici piezoelettrici e non devono essere calcolati. L'esclusiva configurazione di misura di questo sensore piezoelettrico multiasse consente un design estremamente piccolo e compatto. Pertanto, è possibile realizzare modelli concisi di processi dinamici e quasistatici tridimensionali anche in installazioni strette. Sensori piezoelettrici pretensionati di forza-coppia a 6 assi con due flange di montaggio. Misura forze e coppie di reazione sia in trazione che in compressione. Una forza o una coppia di reazione genera una carica elettrica proporzionale. Questa viene trasferita da un elettrodo al connettore corrispondente. Il Sensore di forza-coppia multiasse è costituito da dischi di quarzo di grande superficie ed è quindi molto rigido. L'elevata frequenza naturale che ne deriva è un prerequisito per misurare forze e coppie altamente dinamiche. I due connettori V3 neg. a 3 poli sono dotati di blocco antitorsione. Un connettore ciascuno per i segnali di forza e di coppia. Una volta installato correttamente, il Sensore di forza-coppia a 6 assi è immediatamente pronto per l'uso senza ritaratura.
