Joint ring 21 x 26 form D to DIN 7603, made from 1.4301, bright annealed
Note
The conductivity electrode is designed for installation in pipes.
The conductivity electrode is installed in a socket end, a measuring chamber or a
mounting flange.
When installing the conductivity electrode please consider a min. space of 50 mm
required for servicing and removing the conductivity electrode.
Installation
Attention
Install conductivity electrode horizontally or with a vertical inclination. The measuring
surface must be permanently submerged.
Make sure that the sealing surface of the screwed connection is accurately machined.
Use only the supplied ring joint 21 x 26, form D, DIN 7603, made from 1.4301, bright
annealed!
Do not insulate electrode thread with hemp or PTFE tape!
Do not apply conductive paste or grease to the electrode thread!
Observe the specified tightening torque.
Leave a space of
approx. 15 mm
between the lower end of the measuring tube and
the wall of the pipe.
Do not cut the measuring electrode and the measuring tube!
Mounting conductivity electrode
1. Check seating surfaces.
Fig. 3
2. Place supplied joint ring
3
onto seating surface of the threaded standpipe or flange.
3. Apply a light smear of heat resistant silicone grease (e. g. WINIX
®
2150) to the electrode thread
3
.
4. Screw conductivity electrode into threaded standpipe and tighten with an open-end spanner
A. F. 27 mm. The torque required for tightening
when cold is 110 Nm.
