4.4 ACCESSORIES
4.4.1 Diaphragm leakage detector
The diaphragm leakage detector is an electrical conductivity sensor capable of detecting the presence of
liquid when its conductivity is 0.05 mS or higher. The pump must be provided with the specific diaphragm
flange for housing the detector.
Fit the detector Ref. 29-056 in the lower opening of the diaphragm and
connect pins 8 - 9 as shown in the drawing.

4.4.2 Pressure sensor
The pressure sensor protects the pump from working in overpressure conditions, when the pressure
alarm is activated. Connect the 4 - 20 mA 10 bar pressure sensor Ref. 18705 as shown in the drawing.

The pulse output isolator allows any device to be securely
connected to a pulse output.
The pulse output is a voltage free output. The isolator is not
necessary when the output is connected to a 38 39 40 41 pulse
input of another DOSmart AC.
