3. Carefully place the probe into the vessel. Properly align the
gasket on flanged installations.
4. Align the probe process connection with the threaded or
flanged mounting on the vessel.
5. For threaded connections, tighten the hex nut of the probe
process connection. For flanged connections, tighten flange
bolts.
Model 7y7 Twin Flexible probes contain a TFE weight at
the bottom. This TFE weight has a 0.5" (13mm) hole in it
that can be used to “u-bolt” to the bottom of the vessel or
hang additional weight (up to 100 lbs. [45 Kg.]) to it. This
may be necessary in turbulent applications to limit move-
ment of the probe within the vessel.
Twin Flexible Probes can be shortened in the field:
6. a. Raise the Teflon TFE weight (1) to expose the two secur-
ing devices (2).
b. Loosen the two #10-32 set screws (3) on both securing
devices using a
3
⁄
32
" hex wrench and slide the securing
devices off of the probe.
c. Slide the TFE weight off of the probe.
d. Cut and remove the required cable (4) length.
e. Remove 3
1
⁄
2
" (90 mm) of the rib between the two cables.
f. Strip
5
⁄
8
" (16 mm) of coating from the two cables.
g. Slide the TFE weight back on to the probe.
h. Re-attach the securing device and tighten screws.
i. Enter new probe length (in the appropriate Level Units)
into the transmitter.
NOTES:
1) If the transmitter is to be installed at a later time, do not
remove the protective cap from the probe.
2) Do not use sealing compound or TFE tape on probe con-
nection to transmitter as this connection is sealed by a
Viton
®
O-ring.
2.4.5.2 To install a Model 7Y5 bulk solids flexible twin rod
probe:
The Model 7Y5 bulk solids probe is designed for a 3000 lb.
(1360 kg) pull-down force for use in applications such as
sand, plastic pellets and grains. It is offered with a maxi-
mum 100-foot (30-meter) probe length.
