6.1 Two-wire transmitter
Installation
variations The transmitter type 202610 has a G1 A (1" pipe) thread (1) (underneath the
blue cap) and can be screwed into suitable immersion or flow-through fittings.
Operating
position Preferably vertical, with the membrane (2) pointing down.
Alternative transmitter positions are allowed under unfavorable flow
conditions, but not beyond the horizontal position.
An upwards orientation of
the membrane is not permitted!
Measurement
point The location for the fitting has to be chosen so as to enable easy access for
calibration at a later time. Care has to be taken that the support columns and
fittings are safely secured and largely free from vibration. For submerged
operation in activation basins, a location has to be chosen that is
representative of the typical oxygen concentration.
Pre-assembly For submerged operation it is advisable, for safety reasons, to pre-assemble
the individual modules at some distance from the basin, on a firm surface.
Only then can the final assembly be performed at the desired location.
Screwing in and
unscrewing the
transmitter The connecting cable must be able to rotate freely!
The cable must not be twisted!
Avoid strong tension on the cable. In particular, avoid tugging on the cable.
