Pharmaceutical Formulation with Precision Scales
Precision scales are able to provide highly accurate readings, which is a necessity in the pharmaceutical industry. In the past however, precision scales were extremely expensive, which is why Arlyn Scales pioneered a new scale technology that is revolutionizing the scale industry.
The Old Scale Technology
For decades, the two most popular scale technologies were strain gage and force motor restoration scales. Both of these scales come with their own shortcomings, which prompted Arlyn Scales to develop their industry leading Surface Acoustic Wave (SAW) technology. Before we delve into the details of our SAW technology, we first will explain a bit more about strain gage and force motor scales to help you understand why our Ultra Precision Scales are superior. The strain gage scale gets its name from its load cell, which is called a strain gage because it measures the strain or stress of an object placed on a scale platform. This load cell is attached to the scale platform and measures the weight of the load when an item is placed on the scale platform. When an item is placed on the platform, the load cell bends and generates an electrical signal that the scale’s digital indicator converts into a reading that is displayed.

One of the main limitations of a strain gage load cell is that it must be constructed with relatively thin metal sections known as flexures, because its sensitivity is directly related to how accurate a reading it can generate. This thin metal is more susceptible to shock loading, which is when an object is dropped onto a scale platform from a height, and overloading, which is simply placing an item onto a scalable platform that far exceeds the scale’s capacity. When either shock loading, or overloading begins to occur, the scale can begin to lose accuracy, and if not detected can cause major errors over time. Removing the scale from production can cost a company significant time and money.
SAW technology
SAW scales feature a load cell that measures displacement as opposed to strain or stress. This way it requires a much smaller amount of movement to generate highly accurate weight readings. Because of this, our designers were able to create a load cell that can be manufactured out of a much thicker metal that helps to prevent it from damage due to shock loading and overloading. In addition, because of how these scales are constructed, they’re not nearly as susceptible to drift inaccuracy due to temperature changes or air currents.
These design changes have allowed our SAW scales to not only offer precision accuracy at low capacities, but at capacities up to 500 lbs. as well. No longer will users have to purchase two different scales if they’re looking for precision readings, as well as high capacity. Our SAW scales can allow organizations to save money by purchasing one scale to meet both of these needs.
As if the benefits of SAW scales listed above weren’t enough, the affordability of these precision scales should also be highlighted. SAW scales are priced comparably to strain gage scales, and much less than force restoration scales.
