Containers are often filled by weight. These can include drums, cylinders, tanks, pails, cartons, totes, and almost any other type of box. While it may be more convenient to fill by volume, there are a number of parameters that can affect the accuracy. Depending on the type of material being filled, it may compact differently depending on the temperature or the relative humidity. The particles may cling to each other by static electricity. The filling force may push the material together, or may allow it to incorporate air. The density of the material may differ. Therefore, filling scales may be needed to increase the level of accuracy obtained. The weight can be independently determined by use of the scale, which will generally be underneath the item being filled. Of course it is important to de-couple the filling tube or hose from [+]

Counting the number of items in a batch can be time consuming and inaccurate. If all the parts in a batch weigh the same, then counting scales are an excellent solution for this industrial problem. This type of scale can accept a sample part, and accurately determine its weight. Then, a batch of these parts may be placed on the scale, and it will calculate the number of parts in that batch. This type of device is found in many industrial applications. Counting hardware is one of the most common situations. Bolts, washers, nuts and screws are items that are very standard. So within a batch of bolts, each one will be virtually identical to every other one. Similarly, other hardware items such as hinges, fittings, clips, and tabs are good candidates for counting by weight. Electronic components such as resistors, capacitors, transistors [+]

For industrial applications, it is often important to weigh various items, even in very difficult environments. Difficult environments for electronic scales would include areas that are very wet, or that are exposed to a variety of corrosive chemicals. Depending on the material that is used to construct a scale, water can cause the scale platform, or even more importantly, the load cell, to rust. Even when oxidation just begins on a load cell, it can cause the electronic strain gage to begin to separate from the cell itself. A typical environment that would be considered to be corrosive would be in water and wastewater treatments plants. Corrosion resistant scales should be able to resist a wide variety of chemicals found in such locations, such as chlorine, sulfur dioxide, fluoride, sodium hypochlorite, phosphate, alum, caustics and many others. These chemicals may spill, or [+]
