The Benefits of Weighing Processes

If you are considering weighing samples for quality control, you will first need to know the basic principles behind weighing. Weighing is a noncontact process that uses a scale to determine the weight of each sample. This is important because many volatile chemicals and substances may cause harmful chemical reactions if they are exposed to the open air. It is also important to keep in mind that weighing paper must be kept in a drawer below a top loading balance in order to avoid sticking to it, which can result in a low side error.

The GWP (r) provides documented evidence that a weighing process is reproducible. It aligns with current quality standards in manufacturing and laboratory environments. It can serve as a benchmark for users focused on stable processes and constant product quality. It also enables users to focus on lean manufacturing and regulatory compliance to ensure quality in weighing. For more information, download this white paper. There are many benefits to weighing processes. It can also reduce costs and improve productivity.

Another advantage of weighing is its ability to measure dry bulk materials and flowrates. This method is particularly useful when volumetric correction factors are not necessary. It is also ideal for corrosive materials because it does not require direct contact with the material. In addition to being an excellent choice for packaging and weight control, weighing is also an accepted way to measure products, especially those in bulk. You can use it to measure the contents of a bag, drum, or a tank.

Whether a process is low-volume or high-volume, a weighing process is critical to the quality and consistency of the final product. If a batch fails a quality inspection, it can not only lead to wasted time, money, and resources, but can compromise human health and safety. As a result, pharmaceutical goods must meet strict quality standards. Moreover, if the process fails to meet the standards set by a third party, the potency of the final product could be negatively affected.

Manual weighing processes are still a vital part of many facilities. The human element contributes flexibility to manual processes and allows them to adapt quickly to changing markets. However, there are many inefficiencies in manual weighing processes. The ICS series of scales by Mettler Toledo reduce the variables that lower efficiency and maintain the flexibility of manual processes. With the ICS mode, quick portioning and zeroing without manual adjustments is made with the click of a button. Its ICS mode also eliminates the need for keystrokes and tare weights.

For direct weighing, the weighing instrument should be zeroed properly. Clean weighing paper is then placed on the balance. The substance to be weighed is then placed on the weighing paper. The weight of the substance is then read again and the mass is calculated by subtracting the first reading from the second. The difference between the two readings cancels out the errors made in the first reading. Regardless of the method used, careful zeroing of the balance is important to avoid errors in weighing.

Load cells, also known as load sensors, are made from machined metal. Load cells bend with the mechanical force of a load and convert the force into an electrical signal. Strain gauges bonded at various points on the cell provide a proportional electrical signal when the right spot is applied. The hysteresis factor is typically 0.025 percent. If you want to achieve the highest accuracy possible, choose a high-quality load cell.

Temperature changes can cause weighing errors. Outdoor weigh vessels are commonly exposed to extremes of temperature. The sun heats them up quickly during the day. In the winter, the temperature changes may be low at night and high during the day. Seasonal temperature changes can cause large changes in the temperature of the weigh vessel. If temperatures fluctuate dramatically, they could result in inaccurate weighing results. These environmental factors are another reason to ensure the accuracy of weighing instruments.

Humans have been measuring mass and force for a very long time. Archaeologists have found scales as early as 2000 B.C., indicating that the process was already widespread. Because of trade, people accumulated goods and used them for money. Knowing how much something weighed enabled them to plan events and deal with droughts more efficiently. Ultimately, this knowledge of mass and weight helped us understand the nature of gravity and how it could be used to transport goods. It also helped us develop transportation and aviation.
