Purge-air Supply for Purged sender/receiver units
‡ If used with corrosive gases, the sender/receiver units with the next longest nominal
length than that of the flanges with pipe must be used to minimize corrosion (see Section
2.3.1.1).
‡ The purge-air unit must be in operation.
‡ Connect the purge-air hoses.
Mount the hose clamp loosely on the free hose end, connect the purge-air hose to the
purge-air connection on the sender/receiver units, and secure it with the hose clamp.
‡ The purge-air must be supplied from below; the purge air must flow out in the direction
of the gas flow (see Fig. 3.22).

Installation and connection
Warning
The sender/receiver units may only be mounted if it is safe to do so (for example, if the in-
stallation has been shut down, see Section 1.3.3).
‡ Remove the blind plug from the flange.
‡ Insert the sender/receiver units in the flanges with pipe as previously described, and
screw the components together.
‡ Connect the cable to the evaluation unit at the connector on the sender/receiver unit.
