Abstract:
A device for monitoring the integrity of a diaphragm (1) of a diaphragmed transport unit, having at least one layer, the device comprising: a resistance device (3) connected to one layer and having a measuring device interconnected to a current source (15) via a connecting arm (20),wherein the measuring device is a Wheatstone bridge (2) in which the resistance device (3) forms a bridge resistance (S1, S2, S3, S4) in at least one bridge arm, and an incipient rupture of a layer of the diaphragm has the effect of altering the galvanometer arm voltage (B-D), wherein the resistance device (3) includes four electrical resistances (S1, S2, S3, S4) of a surface conductor loop (19), the electrical resistances interconnect with each other and adjacently connected to one layer of the diaphragm (1) forming the Wheatstone bridge on the diaphragm.
