Smart Super Hybrid Sensor (Smart SHS)
In the past, A&D developed a weighing sensor called the Super Hybrid Sensor (SHS) for the GX/GF series─predecessor to the newly-developed GX-A/GF-A series of multifunctional precision balances. The SHS is a sensor that combines the technology of the electromagnetic force restoration method and a spring-material Roberval structure used for load cells using strain gauges. The SHS takes advantage of both the high resolution of electromagnetic force restoration balances and the high stability of strain gauge load cell balances when loading an object on the weighing pan.
Verification of a Method for Testing Repeatability of Electronic Balances Without Using a Weight
Recently, balances are increasingly used in unfavorable environments such as inside a fume hood or enclosure where airflow is generated. Under such circumstances, it is essential to correctly evaluate the performance of the balance at the actual location of installation, which requires calculating repeatability using a weight. However, in many fields, use of weights is a cumbersome and time-consuming operation. Solution: Load/unload the balance without using a weight by electronically controlling and altering its internal settings. In this application note, this method for evaluating the performance (repeatability) of a balance, called Electronically Controlled Loaded or ECL, is proposed and tested.
ECL and the USP Minimum Weight Standard
ECL, which stands for Electronically Controlled Load, is A&D's unique technology (patent pending) of generating a minute load (0.3 to 3% of the balance capacity) by purposely altering the equilibrium state of the electromagnetic force restoration sensor. A balance with this technology, such as the GX-A/GF-A series, allows the user to test its repeatability performance without using an external weight by automatically calculating the standard deviation from 10 repeated measurements with the said artificially generated load. Further, based on the result of this repeatability test, the balance indicates the minimum weight
in accordance with the United States Pharmacopeia (USP) standard. Currently, ECL can complete a repeatability test and minimum weight calculation in about a minute and a half.
Precise Measurements of Flow Rates of Liquids and Powders with Only a Balance
Balances are often used for measuring flow rates. For example, they are found in production lines where they are used to improve the accuracy and stability of transfer pumps or constant supply devices. They are also used in laboratories to control the flow rates of solutions added to culture media for cell cultures.
