High-Performance Digital Filter (HPDF)
This filter greatly reduces the costs and maintenance required for anti-vibration equipment since
it copes with vibrations without requiring many mechanical measures. What's more, conducting
weighing while applying vibrations, once an extremely difficult task, is now possible.

Vibration-cancelling High Performance Digital Filter (HPDF) Applications
HPDF

HPDF with peak hold● Weighing while using vibrating feeders● Simple checkweigher
A checkweigher (which measures an object while itcontinues to move) can be created.
When weight exceeds near zero, peak hold begins
and is terminated by a timer.

● Weighing while raisingand lowering materials

Scale (load cell)
Scale (load cell)

HPDF with averaging hold● Weighing unsteady objects

When weighing cans and other objects with liquid contents that
tend to shift when stopped, measurement cannot be done quickly as
it takes a long time for liquids to settle. However if HPDF withaveraging hold is used objects can be quickly weighed. Additionally
if a comparator output is used it is possible to determine whether theoutput is acceptable or not.

NEW
Dual HPDF Digital Filter AD-4430A/C/R
When weighing in an environment with large amounts of vibration with only a single filter setting, onlyweighing speed or accuracy can be prioritized.

NEWDual Flow Rate Output AD-4430A/R
The flow rate calculation is performed internally by the indicator then output. This enables smooth control
without delay of the flow rate value. In addition, there are 2 flow rate value output systems which allows
measurement speed to be both balanced and with accurate.

Sequential Weighing Normal batch and Loss-in-weight Functions AD-4430C/R
These models are equipped with sequential filling and dispensing functions for convenient automaticweighing.
When a start signal is received from the device’s F keys or the PLC, signals such as large flow, medium flow,
small flow and weighing end are sent to the PLC by the I/O control and CC-Link (AD-4430C) orModbus (AD-4430R) according to the weight.

USB AD-4430A/C/R
AD-4430A/C/R function settings can be imported and exported
to and from a PC through USB connection.
In the event of device failure, AD-4430A/C/R function settings
can be retrieved from a PC back-up (provided data has been
properly backed-up) and transferred to a replacement
AD-4430A/C/R without delay.
Import/export software (Win-CT or WinCT-UFC) is available for download in
the support section of the A&D homepage.

The AD-4430 series is able to check for disconnected or faulty wires through connection
with a load cell cable. This is convenient for installation or for start-up inspections andperiodic checks.

Up until now, linear correction has
been commonly used, but the AD-4430
series corrects linearity deviations thatlinear correction can't compensate forby using high-order curves, enabling
more accurate weighing.

OutputGravitational Acceleration Compensation
The function compensates for weighing error due to the difference of gravitational acceleration
between the location of calibration and the location of measurement.

Comparator Function
Compares the measurement with HI/OK/LO limits

Hold Function
Select from normal hold, peak hold and average hold.

Remote I/O Function AD-4430C/R
CC-Link or Modbus RTU can be used forremote I/O with control I/O output
settings. You can check inputs of sensors
connected to the AD-4430C/R throughcontrol I/O and turn relays and otherswitches on or off.
