GENERAL
INFORMATION

2

The Hardy Instruments AnyWeigh™ Series Floor
Scales are designed for applications that require a low
profile weighing surface with high commercial accu­racy and reliability. The Hardy Floor Scales can be
configured with a complete range of accessories. The
scales can also be configured to fit any floor scale
application.

The typical platform height is three (3) inches. Each
corner can be adjusted an additional .275” (7mm) to
compensate for a non-level floor or pit mounting sur­face.

The Any-Weigh Floor Scales do not have bearings,
levels or moving parts that can be damaged or wear

out. The active elements of the floor scales are four
precision strain gauge load sensors, mounted on all
four corners of the scale platform. The unique Blind
Hole Load Introduction technology allows the foot to
move to compensate for uneven floors. This ensures
that the load forces are always applied to the load sen­sor at precisely the same point regardless of where the
load is placed on the scale. This ensures you will get
accurate and repeatable weighments.

Each platform load sensor is initially certified for use
in a C2

UNPACKING The Any-Weigh Series Floor Scales are shipped fully

assembled and wired. Inspect the container for any
signs of damage that might occur during shipment.
Since almost all of the Floor Scales are shipped
F.O.B. factory, such damage is normally the responsi­bility of the carrier and should be reported to them.

Step 1. Remove the banding straps and any ship-

ping res traints.

WARNING DO NOT USE HOOKS OR UNCLOSED EYE-

BOLTS OR ATTEMPT TO LIFT THE SCALE
MANUALLY. FAILURE TO USE THE PROPER
LIFTING TOOLS OR LIFTING METHODS CAN
CAUSE PERSONAL INJURY OR PROPERTY
DAMAGE.

Step 2. Screw 2 closed eyebolts into the threaded

holes on the top plate of the scale. (See
Fig. 1)

• Mild Steel - 1/2 - 13 x 1.5” (Hardy Model
Number HI EB2250-1)

Step 3. Attach a chain, cable or nylon strap to the

eyebolts.

Step 4. Use a forklift or crane with rated lifting

capacity that is equal to or greater than th e
total weight of the platform scale to lift the
scale high enough to remove from the

lifting the platform so that it does not fa ll
on equipment or personnel. It is highly
recommended that blocks be placed under
the platform before working near the plat­form scale.

Closed Eye Bolts

COMPONENT
DESCRIPTIONS

FIG. 1 INSTALLING THE CLOSED EYE-

BOLTS INTO THE TOP PLATE

1. Steel Plate Platform - The platform material is

either low carbon steel plate or 304 stainless steel
plate. The low carbon steel platform cover is
made from a single piece of 1/4" A36 carbon
steel floor plate (skid resistant) or smooth steel
plate. The steel platforms are primed and coated
with a tough weather resistant paint (See Paint
Specifications). The 304 stainless steel platform
is made from a single piece of 1/4" diamond tread
(Conforms to ASTM A793-85) floor plate (skid
resistant) or smooth stainless steel plate with a
bead blast finish.

2. Summing Junction Card Assembly - Accessed

by unfastening the face p late on the center s ide of
the platform. (See Fig.2) The summing junction
card routes the excitation voltage to each of the
four load sensors and sums the weight signal

back from them. The C2

second generation

electronic calibration is included with your scale.

FIG. 2 SUMMING JUNCTION CARD

3. Load Sensors - The AnyWeigh series scales use

four (4) steel Advantage like load sensors with
hermetic seals. The output of each sensor is 2mV/
V with 5 Volts DC excitation. For more specifica­tions see the electrical specification section of
this manual.

4. INTEGRATED TECHNICIAN™ (Option) -

(If IT summing card is installed) A built-in sys­tem diagnostics utility, continuously monitors the
weighing system for possible malfun c tions. This
capability also allows the operator to rapidly
troubleshoot a weighing system from the control­ler or indicator.

5. Leveling Feet - Each AnyW eigh series scale

comes with four (4) 304 s tainl ess st eel ad justable
leveling feet. The leveling feet are adjustable to a
maximum of 7mm (.275"). The leveling feet are
attached to each of the load sensors.

SITE PREPARATION • All mounting surfaces for the floor scale

should be level to within 3º, corner to corner,
end to end. Keep in mind that the adjustable
leveling feet have a maximu m adj u st men t of
7mm (.275”).

Any-Weigh™ Series Floor Scales

• Before welding anything on the floor scale,
contact Hardy Instruments Service Center
for instructions and precautions.

• Proper drainage must be provided to prevent
the load sensors from standing in water.

Precautions • Do not do any electric welding on or near the

platform scale.

• Do not drop items to be weighed on the
scale. Set them on the platform scale.

• Do not set items on the platform scale that
weigh more than the capacity of the scale.

• Do not store or operate the scale in environ­ments out of the specified temperature range.

• Do not store other equipment on the scale
even temporarily when it is not used or in
storage.

• Do not allow debris to accumulate on,
around or under the scale.

• Do not set the scale in water or allow water
to accumulate around the scale. Always pro­vide proper drainage.

• Do not let moisture get on or into any of the
electrical interconnections.

• Do not allow static or other electrical dis­charges go through the scale.

• Do not leave the screws for the summing
junction box cover plate loose so that the
junction box is not sealed.

• Do not drop the scale when moving or
installing.

• When driving heavy equipment on and off
the scale for weighing purposes, make sure
that you drive onto and of f of the p latform in
the direction indicated in Figure 3. Also See
Access Ramp Installation Section.

height is within 3 to 3.275" as measured
from the top of t he cover plat e to the to p of
the floor surface. (See Fig. 4)

NOTE: With the scale in place, the clearance ar ound the edge
