Probe Installation

NOTE: For units with remote electronics, the probe connections are

made to the preamplifier. There is a two wire connection

between the preamplifier and the main electronics. Refer to

Section 1.6, Installing a Remote Unit, for details of installing

the remote electronics. Follow Section 1.5, Probe Installation

directions for details in installing the probe.

1.5.1 Installing a Standard Probe

Before installing, ensure the:

• Probe has adequate headroom for installation and has

unobstructed entry in the vessel.

• Process temperature, pressure, dielectric, and viscosity

are within the probe specifications for the installation.

See Section 3.2, Specifications.

To install a probe:

1. Thread probe into mounting bushing on tank.

2. Tighten securely, being certain that the wrench is applied

ONLY to the mounting gland. Refer to Figure 9.

3. Screw the amplifier housing onto the probe. Refer to

Figure 9.

4. Screw housing on the probe until hand tight. Housing

can be wrench tightened to align conduit connection

with conduit.

5. Locate the white wire which is fastened to the probe

terminal (P), Connect the free end of this wire to the

probe connection screw.

6. Proceed to Section 1.7, Wiring.

1.5.2 Installing a Flexible Probe

Caution: Insulated flexible probes are shipped with the cable clamp

and the packing gland nut hand tightened. 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.
