With visual diaphragm rupture sensors, in the event of a diaphragm rup‐
ture, the lowered red cylinder (6) springs forward beneath the transparent
cover (7) so that it then becomes clearly visible - see Fig. 9.
With the electrical diaphragm rupture sensor, a switch is switched. A sig‐
nalling device must be connected to signal the diaphragm rupture.
