2.5.3 Remote Mount with Rigid Probe

2.5.3.1 Main Amplifier

Remote amplifier assemblies are normally shipped from

the factory assembled into an “L” mounting bracket.

Refer to Figure 8 while following instructions.

1. Remove amplifier from mounting bracket.

2. Install bracket in a location which will isolate unit from

temperatures below -40° F (-40° C) and over +160° F

(+71° C) or vibration/mechanical damage. Unit can be

mounted up to 5000 feet (1500 meters) from probe

assembly. Location should also offer easy access for wiring,

calibration and maintenance.

3. Re-install amplifier onto mounting bracket.

4. Screw housing on mounting bracket until hand tight.

Housing can be wrench tightened to align conduit

connection with conduit.

2.5.3.2 Preamplifier

1. Thread probe into mounting bushing on tank.

2. Tighten securely being certain that the wrench is applied

ONLY to the lower probe nut. Refer to Figure 8.

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

Figure 8.

4. Screw housing on probe until hand tight. Housing can be

wrench-tightened to align conduit connection with con-

duit. Proceed to Section 2.7, Wiring on page 8.

2.5.4 Remote Mount with Flexible Probe

2.5.4.1 Main Amplifier

(+71° C) or vibration/mechanical damage. Unit can be

mounted up to 5000 feet (1500 meters) from probe

assembly. Location should also offer easy access for wiring,
