Title:
STRAIN GAUGE AND ELECTRICAL CIRCUIT FOR ITS ADJUSTMENT AND CALIBRATION
Document Type and Number:
WIPO Patent Application WO1982000054
Kind Code:
A1
Abstract:
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).
