1.5 Probe Installation
1.5.1 Installing a Guarded Probe
1. Thread electronics/probe assembly (pre-assembled) into
mounting bushing on tank.
2. Tighten securely (ensure that the wrench is applied
only to the mounting gland). Refer to Figure 8.
3. Proceed to Wiring, Section 1.7, on page 8.
1.5.2 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
Specifications, Section 2.6, on page 21.
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.
1.5.3 Installing a Flexible Probe
Caution: Insulated flexible probes are shipped with the cable clamp
and the packing gland nut hand tightened to permit length
adjustment in the field. The cable clamp and packing
gland nut must be tightened before use.The end of a flex-
ible 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.
1. Attach the weight or anchor assembly to the end of the
probe. Insert the probe through the vessel’s mounting con-
nection, and feed the cable into the vessel. Do not allow
the probe to scrape against the connection threads.
2. Secure the anchor assembly (if used), to the bottom of
the vessel.
