1.4.2 Non-Metallic and Glass-Lined Tank Construction
With plastic, concrete, wood, or any other non-conductive
walled vessels, a ground reference is required. Most com-
monly, this electrode will be in the form of a concentric
ground tube (i.e., stilling well). In questionable circum-
stances, consult the factory. In all cases, a good electrical
connection must be made between the ground surface and
the probe housing.
1.4.3 Transmitter/Probe Assembly
Transmitters with probes up to and including 12 inches
(300 mm) in length are shipped pre-assembled. All other
transmitters are shipped unassembled to avoid damage
during transit. These transmitters must be assembled prior
to mounting. Choose your particular configuration from
the following sections and follow the instructions carefully.

Probe Installation
1.5.1 Rigid Probe
1. Thread the probe into the mounting connection on the
vessel. Tighten securely, making sure that the wrench is
applied ONLY to the mounting nut. Refer to Figure 1.
2. Screw the transmitter housing onto the probe until hand
tight. The housing can be wrench-tightened to align the
conduit connection with the conduit. Refer to Figure 2.
1.5.1.1 Integral Electronics
1. Remove the housing cover. Locate the white wire which
is fastened to the (+) probe terminal. Refer to Figure 3.
Connect the free end of this wire to the probe connection
screw. Refer to Figure 1.
2. Proceed to
Wiring, Section 1.6
.
1.5.1.2 Remote Electronics
1. Connect the positive lead of the interconnection cable
(supplied by MAGNETROL), to the screw terminal at the
top of the probe. Connect the negative lead to the green
ground screw at the base of the housing. Cut the shield;
do not connect it at probe end. Refer to Figure 4 on
page 7.
2. Install the transmitter housing using the bracket (supplied
by MAGNETROL). Make sure to provide adequate clear-
ance to remove the housing cover.
