Achieving Both Precision andSpeed in a Cost-eﬀective Way

www.aandd.jp

What Is the Most Essential Elementof a Weigh Module to You?
The level of control required for ﬁlling, coating, or dispensing amounts inhigh-tech industries has become progressively stricter and stricter. A&D’s weighmodules, the AD-4212A/B series, provide the precision and speed required forbuilding automatic weighing systems for use in such applications, while realizing
cost-eﬀectiveness by various means, including the aﬀordability of the weighmodules themselves. Precision, speed, and cost-eﬀectiveness ― these threeelements are essential to most users, and yet, it has been diﬃcult to achieve all ofthem at the same time.

Adjustable response characteristics

Depending on the amount of drafts and/or vibration at the location of use, you can trade
weighing speed for higher display stability, or vice versa, by selecting one of three preset
response characteristics (FAST, MID, or SLOW). Further, with the AD-4212A, more detailed
settings are possible using its extended function.

Installation ﬂexibility
Wall/panel-mountable display unit
The provided stand can be used to attach the display unit to a wall.
The size of the display unit is also suitable for panel mounting (panelcutout dimensions: 186 mm × 92 mm).

Space-saving with an 80 mm width
The slim separate weighing unit facilitates the compact arrangementof your system.

Securable directly to a base
The weighing unit can be ﬁrmly ﬁxed to a base by removing theleveling feet and using the provided mounting ﬁxtures.

Wall/panel mountingCustomization of the weighing pan
It is possible to design and attach (to either the pan support or the pan boss) a special
weighing pan/receptacle that suits the speciﬁc needs of your system.

Weighing unit

Weighing in vacuum chambers
You can safely install and use the weighing unit in a
vacuum chamber, as it is isolated from the delicate
electronic parts in the display unit.

Data management solutions
Various input/output methods
The following three choices are available:
1. Standard interface: RS-232C, comparator contact output with buzzer (AD-4212A: 3levels*iv / AD-4212B: 3 or 5 levels), and external contact input for RE-ZERO and PRINT
2. AD4212A-01 (optional): BCD output and external contact input for RE-ZERO and ON/OFF
3. AD4212A-08 (optional): Ethernet interface with WinCT-Plus software*iv For 5 levels, the AD4212A-04 (factory-installed option) is available.

Data memory function*vThe display unit stores up to 200 weighing results (or 100 with a timestamp) or the 50
latest calibration results without need for an external memory device. It can also save 20
unit masses to be used in counting mode, or 20 comparator limit settings for laterchangeover.
*v Not available when the AD4212-01 is installed

Durability and protection
Guarded against vertical and transverse overloading
A&D’s patented shock absorber*vi under the weighing pan copes with movement in all
directions so that the sensor is protected from actuator malfunctions.

*vi Not designed to handle impact loads

Chemically resistant, stainless steel construction (AD-4212B)*vii

The splash-proof, IP54 weighing unit with a SUS304 body (SUS316 weighing pan) protects
the sensor from accidental spillage of medical agents, resist ink, coating materials, etc.
AD-4212A has a die cast aluminum body (IP54) with a SUS316 weighing*vii Thepan, but it can be changed to stainless steel by special order.

Auto power ON function
The weighing mode display is automatically activated with AC power, so there is no needto press the ON/OFF key, which is useful when the display is turned oﬀ due to blackout orother accidental power failure.
