Using Smarter Sensor Technology for Weighing Applications

In every industry, it has always been true about weighing that without a user-friendly, efficient, and accurate scale, customer satisfaction and profitability are compromised. Reliable product measuring is very important not just for supervising and monitoring sales and inventory but also for guaranteeing compliance with industry regulations.

At A&D Weighing, the pursuit for the most reliable and accurate scale continuously gives rise to features and advantages to its customers that enable them to better run their businesses. The Smart Super Hybrid Sensor (SHS) is the most recent advancement to that commitment to excellence.

What does “Smart Super Hybrid” mean? To put it simply:

  • Smart: It makes use of the best features of its predecessors and integrates high resolution and fast stabilization.
  • Super: It outperforms its predecessors in every aspect of accuracy and performance.
  • Hybrid: It combines the best qualities of two technologies: To realize the renowned results of the SHS, they integrated magnetic force restoration and single-point parallelogram load sensing technologies.

An Evolution in Design: The Advancement of SHS Technology


The SHS was initially developed as part of the GX/GF series of precision balances. It is a sensor that integrates both the high stability of strain gauge load cell balances and the high resolution of electromagnetic force restoration balances when loading an object on the weighing pan.

Compact SHS

After the triumph of the initial design, A&D subsequently developed the Compact Super Hybrid Sensor (C-SHS) for the FZ-i/FX-i series of more economical precision balances, incorporating a miniaturized design achieved by using a double-lever system.

Smart SHS

The Smart SHS for the GX-A/GF-A series of balances was developed by A&D and was launched only recently. The most recent advancement includes the best features of the C-SHS and SHS and integrates high resolution and fast stabilization while decreasing the number of parts (to reduce time and cost of repair).

Smarter All Around: Construction and Features

Easier Corner-Load Adjustment

With adjustment screws, corner-load adjustment is possible and can be reversed whenever needed. The GX-A/GF-A series enables the adjustment screws to be accessed without removing the sensor from the balance.

Wider Range of Readability and Capacity with One Sensor

Since the double-lever system has a higher lever ratio, it can now obtain a resolution of up to 1/3,000,000 and a capacity of 10 kg for the Smart SHS.

Increased Display Stability

The force motor creates a stronger magnetic force using two small magnets. Upon integration with the double-lever system, balancing needs a considerably weaker electronic current. As a result, the force coil produces less heat and the display stability is increased.

Furthermore, the force coil is molded by using liquid crystal polymer (LCP), which offers increased protection against moisture and decreases the negative impacts of variations in humidity on the measurement stability.

Reduced Cost of Repair and Maintenance

The number of components in Smart SHS is less when compared to the C-SHS, which, in turn, decreases the repair/maintenance cost.

The technology base offered by Smart SHS has enabled A&D to launch the Apollo series of balances with a host of new advantages.

Case in Point: The Apollo (GX-A/GF-A) Series of Balances

The Apollo series is powered by Smart SHS technology and includes three important advances to offer ideal weighing results, even under the most demanding lab or production settings. These new aspects include Electronically Controlled Load (ECL), Impact Shock Detection (ISD), and Flow Rate Display (FRD).

Electronically Controlled Load

The Apollo series incorporates a patent-pending ECL technology that enables the user to carry out a diagnostic check and repeatability test without using an external test weight. With Dia-Check, users gain a daily precision verification test at the touch of a button and within 2 minutes. Furthermore, Apollo can smartly determine a standard deviation and estimate the minimum sample weight with Quick-MinS. It enables users and service technicians to make sure operations are USP 41-compliant with Min-S-Alert.

This attribute offers an innovative diagnostic tool that guarantees critical measurements are in accordance with industry standards such as USP 41 and 1251. The ECL feature performs this with the single touch of a button and in an adaptable and flexible way to meet the SOP frequency needed for sensitive or risky materials.

Impact Shock Detection

Impact-Alert — the patented ISD function on the Apollo range — shows the magnitude of impact shocks to the weight sensor at four levels. It also gives audible notification for higher impact levels, which should be prevented. The ISD feature also records impacts through the Shock-log that records time, date, operator ID, and shock level, rendering it easier for quality control to pinpoint.

When vertical and transverse environment forces are non-predictable, the new feature for detecting impact shock becomes essential. This real-time feedback mechanism avoids equipment damage and helps managers to change in-line or manual processes similarly. ISD offers the information needed by workers in lab or production environments to prevent repetitive impacts.

Flow Rate Display

The Apollo series incorporates an FRD function to eliminate irregularity that can happen in conventional filling and dosing applications. The FR-Calc feature computes and shows the mass or volume flow rates to eliminate the “time-clock disparity” present in conventional PC techniques. The series also incorporates an FR-comparator, which enables monitoring of flow rate data to make sure that it is maintained within specified limits. Furthermore, the tare value can be saved in non-volatile memory so that the remaining amount of the material in the container can be shown again, even if power is interrupted for any reason at the time of loss-in-weighing measurement.
