Title (EN) STRAIN GAUGE AND ELECTRICAL CIRCUIT FOR ITS ADJUSTMENT AND CALIBRATION
(FR) JAUGE DE CONTRAINTE ET CIRCUIT ELECTRIQUE POUR SON REGLAGE ET SON CALIBRAGE
Abstract: front page image
(EN)A strain gauge comprises a resistor strain sensitive element (1), a mechanical compensating element (10) and a separating element (9) made of a material having a linear expansion coefficient which is substantially lower than that of the material of the mechanical element (10). The latter carries a heating element (15) and a resistor strain element (16) intended both for programmed presetting of the deformation of the mechanical element (10) during the process of adjustment and calibration of the gauge. The electrical circuit for adjustment and calibration of the gauge represents in itself a bridge network, each of its arms comprising a resistor strain (3, 4) of the sensitive element (1). The heating element (15) is connected to one apex (32) of the halfbridge network and the resistor tensor element (16) - to its other apex (37).
(FR)Une jauge de contrainte comprend une resistance (1) sensible a une contrainte, un element de compensation mecanique (10) et un element de separation (9) fabrique en un materiau dont le coefficient d'expansion lineaire est sensiblement inferieur a celui du materiau de l'element mecanique (10). Ce dernier porte un element de chauffage (15) et un element a resistance (16), tous deux destines au prereglage programme de la deformation de l'element mecanique (10) pendant le procede de reglage et de calibrage de la jauge. Le circuit electrique de reglage et de calibrage de la jauge represente en soi un reseau en pont dont chaque branche comprend une resistance (3, 4) de l'element sensible a la resistance (1). L'element de chauffage (15) est connecte a un sommet (32) du reseau demi-pont et l'element a resistance (16) est connecte a son autre sommet (37).
