Mounting to telescopic rod immersion holder
• Mount the flexible mounting bracket on an existing handrail or on a separate holder, diameter
32...50 mm / 1.3...2.0" or square 28...42 mm / 1.1...1.7". The bent lip on the mounting plate
shall be on top and faced toward the liquid or tank.
• Adjust the mounting bracket to the correct angle and tighten the nuts.
i The bracket shall be fixed to the rail, and must not be able to rotate around it.
• Adjust the length of the telescopic rod as necessary by twisting the nuts while holding the rod.
Do not extend the rod sections beyond the black lines. This could lead to rod damage.
• Insert the PVC rod holder with the telescopic rod into the mounting bracket. Make sure that
the guide tracks of the rod holder are properly seated in the bracket.
• Fasten the safety-locking clamp.
• Check that the mounting bracket is safely fixed to the rail for the spring to work the way it is
intended.
3.3.3 MAA 2000 sensor holder and telescopic rod
In standard applications the PAS 2000 telescopic rod version gets delivered pre-assembled. In
case the assembly needs to be done on side, the sensor is inserted into the telescopic rod and
fixed with two POM half shells, which additionally integrate the flushing system (see chapter 8).
NOTE!
To ensure easy access to the electrode in case of maintenance, make sure that the removable
part of the electrode holder is fixed clearly outside of the POM sensor holder.
