1.5.2 Flexible Probe
Caution:
Flexible probes are shipped with the cable clamp and the
packing gland nut hand tightened to permit length adjust-
ment in the field. The cable clamp and packing gland nut
must be tightened before use. The end of a flexible probe
MUST be kept taut by attaching the anchor end at the
bottom of the vessel or by using a MAGNETROL supplied
probe weight.
Caution:
Do not discard the Mylar housing insulator.
Caution:
The probe cable must not be in contact with any metallic
surface in its final installation position.
1. Attach the weight or anchor assembly to the end of the
probe. Insert the probe through the vessel’s mounting con-
nection and feed the cable into the vessel. Do not allow
the probe to scrape against the connection threads.
2. Secure the anchor assembly (if used) to the bottom of
the vessel.
3. Apply thread sealant to the mounting nut. Screw the
mounting nut into the mounting connection until tight.
4. Remove the Mylar housing insulator located over the
clamp. DO NOT DISCARD.
5. Loosen both socket head screws from the clamp. Pull the
clamp and Teflon
™
retaining bushing off of the probe.
6. While holding on to the probe cable, loosen the upper
packing gland nut. DO NOT ALLOW THE PROBE
CABLE TO FALL INTO THE VESSEL.
7. Pull the excess cable up through the packing gland nut
until the cable is taut. Tighten the packing gland nut.
8. Cut the cable 1.35 inches (34mm) above the packing
gland nut and strip off 1.25 inches (32mm) of insulation.
9. Slide the Teflon
™
retaining bushing onto the cable and
seat it into the packing gland nut. Slide the clamp onto
the cable and seat it against the Teflon
™
retaining bushing.
