mounting plate can be made of a flat plate (A) with a 7/8-

inch hole drilled for mounting the transducer. Transducer

mounting plate (B) shown should only be used when

absolutely necessary.

For heights greater than 12 inches, the base plate

dimensions should increase. Also, angle iron braces,

welded between the top of the pipe and the base plate,

should be added.

When the support stand is ready, position it so the

transducer mounting plate is located at approx imately 5/8

inch from the magnet assembly. Secure the support stand

to the floor.

Install the transducer in the mounting plate with two

locknuts. Adjust the gap between the transducer and the

magnet tip to dimensions shown in Figure 2, and secure

the transducer to the mounting plate.

WARNING

A guard must be installed surrounding the

magnet assembly and the transducer to

protect operating personnel. Guards are not

available from Avtron as they must be tailored

for each installation.

WIRING

Interconnection cables specified in the wiring diagram

below are based on typical applications. Refer to

system drawings for specific cable requirements where

applicable. Physical properties of cable such as abrasion,

temperature, tensile strength, solvents, etc., are dictated

by the specific application. General electrical requirements

are: stranded copper, 22 thru 16 gage, braid or foil with

drain wire shielding, 0.05 uF maximum total mutual or

direct capacitance, outer sheath insulator; length: 1000 ft.

maximum. The customer-supplied cable must be retained

to the NEMA 12 box with a watertight fitting.

CAUTION

The rubber jacketed transducer cable has

been selected to provide impact and abrasion

resistance. Also, strain relief is provided at

the transducer cable entrance to the NEMA

12 type terminal box and at the transducer.

The transducer cable, however, should be

protected from severe impact, abrasion, and

chemical stress.
