Valve module for compressed air-driven sensor cleaning in the IQ SENSOR NET, System 28X


Design according to the minimum requirements defined by ATV (Waste water association) 
in bulletin M256 for meters to be used at waste water treatment plants.

Dual IQ / valve module for compressed air-driven sensor cleaning in the System 28X.

Requirements for this: dry compressed air, free of oil and dust, 5 bar, approx. 40 NL/min

Power supply:
Directly via the auxiliary voltage of the DIQ/S 28X measuring transmitter

Instrument protection:
IP 66 type of protection

Enclosure material:
Polystyrol

Dimensions:
94 x 94 x 57 mm (W x H x D)
