Function

7.2.1 Pumps prepared for a diaphragm breakage indication

❏

Special dosing head flange for inserting the optoelectronic sensor

❏

Optoelectronic sensor, contains

-

infrared sender

-

infrared receiver

In case of a leaking diaphragm:

❏

Dosing liquid penetrates the dosing head flange.

-

The light refraction will be changed.

❏

The sensor produces a signal.

-

The electronics switches two contacts which can be used e. g. for
triggering an alarm device or switching off the pump.
