Analytical Weighing Balance

1. Feedback control:
This function outputs the difference from the target value in filling and packing machines when there is a difference between the target and actual values (pulse width output method using DO output and zone output method using multiple DO outputs).

2. Weighing Mode:

• Addtion of Optimal Mode
• Optimal mode extends the sampling time to ensure accuracy.
• This mode is effective for measurement of small, light products and long (dimension) products.
• Note: The judgment timer is extended leading to a throughput that is lower than standard judgment processing.
• Additionally, rejection processing may not be received in time due to delayed judgment output of rejectors connected at subsequent stages.

3. Target weight tracking:
The target weight tracking function calculates a moving average for weighing values and sets a new target value based on the target, high limit and lower limit values and the settings for the target weight tracking. This function allows the checkweigher to perform checkweighing while tracking changes in weight of the products. Select “Enable” to use the target weight tracking function.

4. Reject confirmation:
Reject confirmation is a function for monitoring products using a photosensor that is attached to the ending side of the flow, such as the passing or discharging side of a rejector. Allows users to check for errors in which products other than those specified pass as OK.

5. DO (Digital Output) additional features:
Consecutive Fail, Error Output, Total Number Count, Conforming Item Count Bin Full, Reject Confirmation

6. DI (Digital Input) additional features:
Air Pressure Error, Bin Full, Emergency Stop, Reject Confirmation

7. Dump Printing:
Print raw data summary results or statistical data on an RS-232C connected printer capable of dump printing (such as the AD-8126). Print the raw summary data or weighing data from processing small numbers (approximately 100pcs/min or less). Data can be sent to a serial connected computer if desired.

8. Serial connection:
Weighing results transmitted by RS-232C after each measurement.

Static electricity, while often overlooked, can be a fatal source of error in precise weight measurements. With the BM Series, A&D seek in various ways to help you perform sometimes-tricky analytical weighing with simplicity and accuracy, including the elimination of static electricity. The world of micro grams (µg) is now accessible to all researchers!

Motor-driven Internal Calibration Mass:
The internal mass of the BM Series allows you to perform calibration quickly and correctly even if you are not skilled at calibrating balances using external masses.

Automatic Self Calibration:
The balance can self-calibrate automatically when it detects a change in ambient temperature.

Automatic Response Adjustment:
The balance automatically adjusts its response characteristics (FAST, MID, or SLOW) by analyzing the influence of drafts or vibrations on the stability of the display value. (Manual adjustment is also possible.)

Special Pans and Holder:
The BM-20/22 includes three sizes (10 pieces each) of aluminum analytical pans, two pans for weighing PM filters , and a microfuge tube holder as standard.

One Touch Automatic Calibration:
The accuracy of your balance is assured with one key press.

Large Weighing Chamber for Improved Usability:
To block drafts, A&D adopted a double-ring structure around the weighing pan and two vertical shields under the separation plate. This offers more space and easier operation than conventional 1 µg balances with a secondary breeze break in the chamber.
