to the process. A cable strain relief fitting should be used on the upper end of the pipe. In the kits a
wire bracket is provided to aid in supporting the assembly.
NOTE: An optional protective shroud, Part No. PROTECTOR-3 should be used on the electrode
end of the probe to protect the electrodes from accidental contact with the tank bottom, sides or
objects in the process.
3.6. Submersion Mounting Series 6 Differential Probes
Refer to Dwg# N105-73
a) A submersion mounting kit, STC60-6 is available from Water Analytics which includes 4 ft. of 1”
pipe, 1-1/2” x 1” reducer and a strain relief fitting. Proceed as follows, either with the kit or with your
own hardware:
b) Install the optional protective shroud, Part No. PROTECTOR-6 on the probe by threading the probe
cable through it. The shroud will contact the shoulder on the probe.
c) Install the compression fitting components on the probe in the order shown in the drawing below so
that the pipe thread is towards the cable end of the probe. If you are concerned that the shroud
may get pushed up and expose the electrodes you can lock it down by the positioning of the fittings.
d) Snug up the nut of the compression fitting to locate it in the desired position. Hand tighten as much
as possible, then turn 1/2 turn with a wrench.
e) Apply a thread sealant to the pipe thread portion of the compression fitting and screw a 1-1/4” x 1”
NPT reducer to it.
f) Route the sensor cable through an appropriate length of 1” pipe and using thread sealant, screw the
pipe into the reducer on the probe. The cable end of the probe should not be exposed to the
process.
3.7. Flow-through tee mounting Series 8 Differential Probes
Refer to Dwg# N105-72
a) Apply pipe sealant to the electrode end of the probe and screw it into the AquaMetrix union tee w/
adaptor (Part No. AM-MH538N9A) or any standard 1-1/2” NPT tee.
3.8. Flow-through tee mounting Series 6 Differential Probes
Refer to Dwg# N105-73
a) Take the compression fitting apart. Apply pipe sealant to the 1-1/4” NPT thread and screw this part
into a 1-1/4” tee. A larger tee with an appropriate reducer may be used.
b) Put the compression fitting components on the probe in the order shown in the drawing. They
should be in such a position that the electrodes will be in the pipe stream but not touching the
opposite side of the tee.
c) Remove the protective cap from the probe and place the probe in the tee. Now tighten the nut by
hand as much as possible, then turn 1/2 turn with a wrench.
