ABSTRACT:
The load cell, in particular for weighing systems, consists of a compressively loaded member which is provided with strain gauges. In order to prevent measurement errors caused by elevated temperatures or other environmental influences on the connection between said strain gauges and said member, the strain gauges are deposited on a separate support by means of thin-film techniques, and the support is welded to the center of the member.
