The diaphragm monitor monitors the multi-layer diaphragm for leaks and
faults. The middle diaphragm layer of the multi-layer diaphragm has slots.
The slots are connected by a channel in the dosing head (1) to the dia‐
phragm monitoring sensor (2). As soon as one of the outer diaphragm
layers ruptures, feed chemical or hydraulic oil will reach the diaphragm
monitoring sensor. The diaphragm monitoring sensor generates a signal.
