connection which is suitable for integral electronics or conduit connection.
The insertion length is fixed, but may be shortened in the field.
Model P42T, Y & G
This is a rugged heavy duty unit for the toughest and most corrosive services.
It is also suitable for high pressures. The strong metal body is suitable for
rough services. The electronics unit can be integrally mounted on the gland
head. The insertion length is adjustable.

Model P43 Probes
Cable
Supported Electrode Upper Unit, Plastic Body
NOTE: The length of all electrode cables can be changed in
the field and resealing the cable(s) to the process connection is easily accomplished.
Model P43A
This assembly is equipped with a plastic body, cable jacket, and shield. Seals
are EPDM rubber. It is suitable for most applications at moderate temperatures
and pressures. Up to 4 electrodes may be accommodated. Cable jackets extend
into the body and are clamp sealed. This prevents failure due to shorting out
by buildup and moisture which commonly occurs at the old fashioned cable to
rod connections used on some competitive low cost OEM designs. There is no crack
or overlap to allow moisture to contact the cable. The basic PVC housing provided
(140°F limit) is Type 4X. Plug kits are provided for spare holes. The trim is
stainless steel.
Model P43C
This unit is a larger version of the Model 43A, and can accommodate up to 7
electrodes.
Model P43J
This probe assembly is equipped with a nylon blend plastic body, and Buna-N
cable seals. It is not available with a head housing. Cable wires must extend
to the remoted electronics unit or to a junction box.

Model P44A-D Probes
For
Water & Other Conductive Liquids
Rod Electrode Probe, Regular Duty, Plastic Body, Multiple Rod Type, Tip Sensitive,
Pressure Tight, ANSI Pipe Connection
Model P44A
This unit has a plastic body, Teflon® jacket, and EPDM rubber seals. It is used
for both general purpose and corrosive applications. The electrode rod is continuous
and clamp sealed into the body. It does not have a small weak joint where it
can break off as do common light duty designs, neither can the rod vibrate loose,
unscrew, and fall off. A type 4X PVC hoseproof housing for the remoted electronics
is provided. Plugs are provided for spare holes. Trim is stainless steel.
Model P44B
This unit is same as the Model P44A, except each rod has a full length Teflon®
jacket that extends to within 1" of its tip. The jacket is continuous and
is clamp sealed inside the body. There is no gap in or "lapping" over
the jacket seal; low cost designs such as those commonly allow buildup material
or condensed moisture to short out the probe and cause false switching to occur.
Model P44C
This unit is larger version of the Model P44A; it can hold 5,6, or 7 bare electrode
rods.
Model P44D
Same as Model P44C, except equipped with Teflon® jackets to within 1" of
the electrode rod tips.

Model P44F-G Probes
For Steam, Water & Other Conductive Liquids
Electrode Probe, Heavy Duty, Metal Body, Multiple Rod Type, Tip Sensitive Pressure
Tight, ANSI Pipe Connection
Model P44F
This assembly is heavy duty for severe services or when the highest reliability
is required. Electrodes are one piece rods passing completely through the body
and then clamp sealed inside the body. Seals and electrode jacket are PTFE Teflon®
(jacket extends 1" below the process connection). Safety stops prevent
rod blowout even at 3000 PSIG pressure. Both upper and lower rod jackets are
clamp sealed to prevent failure due to shorting by moisture condensation and
deposits. A type 4X hoseproof housing for remote electronics unit is provided.
Model P44G
Same as Model P44F,
except the lower sensing electrode jacket extends to within 1" of the rod
tips.
Model P44H
Same as Model P44F, except the electronics are integral to the unit. A type
4X hoseproof housing for integral electronics unit is available.
Model P44J
Same as Model P44G, except the electronics are integral to the unit. A type
4X hoseproof housing for integral electronics unit is available.

sizes, as well as those mating with "Acme Nut". "APC", "Cherry-Burrell",
etc.; are available. The electronics unit may be mounted directly on the head
of the probe body, or remotely, as desired.

Model P46 and P47 Probes
For
Sumps, Vented Tanks, And Atmospheric Pressure Services, (Vapor Seal Only, Not
Pressure Tight)
Upper Mounting Support Units For Cable Supported Electrode Probes, Adjustable
Knot; Multiple Cable Style
Each probe wire is equipped with a rubber "O" ring and a 300 SS plate
which provide a vapor seal where the cable exits the body. These units are not
suitable for pressure services or where the liquid is fuming or boiling. The
length of each electrode cable is adjusted by changing the position of a simple
overhand knot. Plugs are provided for unused holes. A basic type 4X hoseproof
PVC housing (150°F limit) for use with remote electronics is provided on the
P47 series. The P46 series utilizes a cast iron condulet body for strength.
Integrally mounted electronics are not available with these styles. The cable
wires normally extend to the electronics unit or to a junction box. An optional
clamp type terminal strip for junctioning mounted in the housing is available.
Model P46A
This assembly extends out over an open pit or tank. It attaches to the threaded
end of a rigid 1/2" NPT conduit which supports it. It is made of heavy
cast iron. It can support up to 4 electrodes.
Model P46B
This unit is a larger version of the Model P46B. It mounts on a 1" NPT
conduit thread and can accommodate up to 8 electrodes.
Model P47D
This assembly is mounted on a vertical NPT or flanged pipe connection. It is
equipped with a basic housing and NPT conduit connection. A clamp type terminal
strip, located in the basic housing is optional.
Model P47E
This is a larger version of the Model P47B probe assembly; up to 7 electrodes
may be accommodated.
Model P47F
This is still larger version of the Model P47B probe assembly; up to 13 electrodes
may be accommodated.

Cable Supported Electrode Lower Sensing Unit
TYPE "SE"
This is our most versatile lower electrode unit. The electrode is sealed inside
an insulating body which has a long isolating path to other electrodes, tank
wall ground, etc. The unit is equipped with dual Viton seals for utmost reliability.
It can be used in strong acids, alkalies, etc. at high temperatures. The Teflon®
cable insulation is immune to almost any corrosion.
TYPE "SJ"
This is a compact unit which is equipped with a close fitting Teflon® jacket
around the body. The jacket does not cover the cable connection nut. Isolating
path to ground is much shorter than in the type "SE". It is suitable
for most normal applications where switch points are spaced apart in a medium
or large size tank.
TYPE "ST"
This unit is similar to the "SJ" except that it has a bare stainless
steel cable that has been coated with Teflon®. It is intended for dirty rough
services that are only somewhat corrosive.
