Parts Counting Scales are useful in a wide variety of different industrial applications. These industrial scales are used when a large quantity of identical parts has to be accurately counted. This is suitable for the hardware industry where nuts, bolts, washers, rivets and other items are counted. Similarly, the electronics industry used counting scales for resistors, capacitors, diodes, and integrated circuits. Printed items are yet another area.
Standard operation requires a small number of parts to be placed on the scale platform. The quantity of the sample parts are entered by the user, so the scale can determine the weight of a single piece. Now, when a large quantity of parts is placed on the platform, the scale can calculate that quantity.
One of the most important specifications for a counting scale is the resolution, or readability. If small parts are being counted, a large percentage error can occur if the scale does not have enough resolution. In this case, either a larger number of sample parts should be used, or a scale with higher resolution should be chosen.
Most of the lower cost counting scales use standard strain gauge technology. This includes Scale Compare’s selections of the A&D FC5000i, Arlyn 820X, CAS SC-05P, and Digi DC-788-10. The A&D FC5000i and the Arlyn 820X have a superior readability of 0.001 lb. The other two fall slightly behind at 0.002 lb. All of these scales will accurately count parts that are not too light. Generally, the load sensors of all of these scales are fabricated from aluminum. An exception is the Arlyn 820X, which uses stainless steel. This will protect the scale from accidental damage from shock loads caused by dropping items onto the scale platform.
For much better accuracy, the A&D FC5000Si uses force motor technology, and increases the readability by a factor of 2. The Arlyn SAW-X uses their patented Surface Acoustic Wave technology to increase the readability by a factor of 10, resulting in exceeding accurate results. The SAW-X has an overload factor of 500%, far exceeding the other technologies. This provides excellent protection from shock load and overload.
