Introduction
The cleaning unit is designed for automatically cleaning the sensor cartridge membranes
(refer to
Figure 1 on page 2 ). The streamlined design of the cleaning unit minimises the
points where interferences could occur. Refer to Figure 3 on page 3 for the cleaning unit
dimensions.
The cleaning unit is exactly matched to the sensors so that the sensor cartridge
membranes are kept clean even in difficult inlet applications. The cleaning head requires
compressed air (2 to 3.5 bar (29.01 to 50.76 psi) maximum) that is produced by a
compressor or supplied from an existing compressed air system.
Important Note: The compressed air must be oil free.

charge to the user.

end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.
