A&D Checkweigher
Checkweigher with best -in-class 0.01 g resolution and high level 0.08 g (3σ) accuracy
Better accuracy in high speed range improved by increased environmental resistanceand newly equipped HPDF (High Performance Digital Filter)
A&D’s Checkweighers are used by customers in a variety of industries around the world,
especially in the food industry. As a weighing product manufacturer that is well received
by a wide range of customers, we have developed a Checkweigher that has evolved toenable faster processing. It is equipped with a load cell developed specifically for
Checkweighers and a new CPU, as well as being waterproof (IP65 grade) as standard
while being priced reasonably.

High accuracy (3σ): 0.08 g
A&D has achieved high accuracy (0.08 g, 3σ) by installationof a newly designed digital load cell unit and a CPU whichenables high speed processing.

Accuracy in high speed range is improved by max. 80%.*
Contributes to increased productivity
The design has evolved to be less susceptible to wind and vibration than previous models, and environmental
resistance has been greatly improved.
AD-4961A series is equipped with a new CPU which has increased processing power, and the newly implemented
vibration elimination filter HPDF (High Performance Digital Filter) has been optimized to increase accuracy by up to
80% at high speeds. *Checkweighing process can be performed better at high speed range than conventional models, contributing to
improved production capacity and efficiency.

High repeatability checkweighingby optimizing checkweighing settings
The optimum checkweighing settings are automatically set when the weight and length of weighed products, andthroughput or conveyor belt speed are input.
Setting for vibration elimination filter (HPDF) is also automatically selected. So, checkweighing can be performed easily
regardless of the operator. Also, dynamic compensation can also be set easily by passing products through repeatedly.

* When compared to data from A&D’s conventional models

Assures consistent quality by way of the Operation History function
and restricting operation according to user level
Each user is registered and user level function allows you to restrict
operations for each registered user.
The Operation History, which records users and operation details,
as well as Weighing History can be saved onto a USB flash drive.
Weighing History can be summed up as a record for HACCP
management by receiving signals of inspection results from an X-ray
inspection system or a metal detector.

A&D Checkweigher
Touchscreen has evolved to be even easier to read and use, making it easy to set up even for first-time users.
Waterproof (IP65) as standard.
Easy to install Checkweigher that can easily be integrated with other equipment.
Waterproof structure: IP65
Stainless steel cover for display unit is available as an option.

PDF output function reduces report creation time.
Screenshots can also be saved.

Equipped with a 7-inch color touchscreen and a new CPU, operability has been improved and
AD-4961A series is easier to use.
AD-4961A series have high visibility and operability, and even first-time users can easily set up the system.
By registering and displaying a photo of the weighed product, a user can immediately check what product isbeing produced. The standard display unit is made of a reasonably priced, waterproof resin. If preferred,a stainless steel cover is also available as an option.

Summary results, control charts, and histograms can be displayed.
After checkweighing is complete, press the "PDF output" or"CSV output" key on the Summary screen of the data you wantto save, and each file will be output to a USB flash drive.
A screenshot of the touchscreen can easily be saved to a USB
flash drive by pressing the camera icon in the upper right corner.
You can use this function to create work instructions, manuals,
and various reports.

Wireless LAN as standard feature enables remote monitoring.
Also, remote maintenance is available.
Wireless LAN function is equipped as a standard feature. *1 *2 Various data such as Summary Data can bemonitored on tablets, etc., in another room, even during weighing.
Also, you can operate a Checkweigher from a PC by connecting it to a PC.
In addition, the AD-4961A can be used for offsite maintenance by "remotely operating *3" a PC connected to theAD-4961A via LAN from another PC in a remote location via an Internet connection.
USB interface as standard specification

A wide variety of external interfaces for various types of communication.

*1 The standard wireless LAN is for monitoring only and cannot be used for remote operation.
*2 Wireless LAN can be used depending on the regulations in your region.
*3 In addition to the AD-4961A, other necessary equipment such as a PC and an Internet connection
must be provided by the customer.

The provided contact points can be used to connect the outputs of Rejector and/or alarm, and also for the inputs
from a metal detector or an X-ray inspection system, etc.
RS-232C or RS-485 (selectable) interface (for connecting to Modbus RTU, barcode reader, PC, PLC, etc.),
wireless LAN functionality (for remote monitoring), wired LAN interface (for remote operation, Modbus TCP/IP, etc.),
and USB interface are provided as standard features. These various connection interfaces enable a Checkweigher
to be connected to an X-ray inspection system and/or metal detector.
Furthermore, data can be saved to a USB flash drive and output to a printer.
In addition, the communication function enables interlocking and linking to other devices in the production line.
