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 4.

2. Install the transmitter housing using the bracket (supplied

by Magnetrol). Make sure to provide adequate clearance to

remove the housing cover. Refer to Figure 3.

2. Proceed to Wiring, Section 1.7.
