The Advanced Guide to Purchasing Ultra Precision Scales

The advanced guide to purchasing ultra precision scales

Does your business need a high precision scale to measure raw materials or delicate substances? You can ensure compliance and accuracy with the right weighing device. Digital scales are one such example. Read our advanced guide to purchasing ultra precision scales to make an informed decision.

Once upon a time, there were only 2 industrial-scale options for consumers to choose from Strain Gage and Magnetic Force Restoration (MFR) scales. With these 2 options, consumers often had to choose between scales capable of delivering reasonable performance and moderate cost for their specific range of scale capacities, or highly accurate readings at very high costs, generally limited to lower capacities. There wasn’t a scale that could provide high accuracy, for multiple capacities, at a reasonable cost…until now.

Arlyn Scales, a leader in design and manufacturing in the scale industry for over 30 years, created a new scale technology that can do both: Surface Acoustic Wave (SAW) technology.

Arlyn’s series of Ultra Precision Scales encompass the new technology, which is unlike Strain Gage and Magnetic Force Restoration scale technologies in all the best ways. These precision scales are available in a range of maximum capacity and readability combinations. For example, maximum capacities range from 5 pounds to 1,000 pounds. The readabilities delivered are within 0.00005 pounds, depending on the maximum capacity of the scale.

If you are looking for a scale that will deliver extremely accurate weight readings, then Arlyn Scales’ Ultra Precision Scale might be just the scale for you. Here is everything you need to know about Surface Acoustic Wave technology, Ultra Precision Scales, and how to choose which scale features and specifications are right for your particular weighing application.

An Overview Of Surface Acoustic Wave Technology

Inside every Ultra Precision Scale manufactured by Arlyn Scales, there are 2 Surface Acoustic Wave transducers. The transducers are installed at a set distance apart underneath the scale’s weighing platform. When an object is placed on the platform, the distance between the transducers increases, and the new distance is correlated with the weight of the load on the platform.

The transducers are the most vital component of the weighing process. 1 transducer acts as a transmitter, while the other transducer serves as a receiver. When a load is placed on the scale platform, the transmitting transducer sends a wave to the receiving transducer.

The receiving transducer takes the wave, amplifies it, and sends it back to the first transducer—and the wave continues to go back and forth between the 2 transducers. SAW technology measures the time it takes for the initial wave to travel from the transmitting transducer to the receiving transducer and the measurements are recorded digitally.

Accurate Weighing Is All In The Load Cells

Every electronic, digital industrial scale is only as good as its load cells. The load cells in our Ultra Precision series are made from a special alloy of heat-treated aluminum and are thick and strong. This is because scales with SAW technology measure displacement rather than strain, meaning the amount of bending required for SAW scales is much less than the amount needed for standard Strain Gage scales.

The thicker cells can endure heavier loads than the thin metals used in strain gauge load cell design. Ultra Precision Scales are less susceptible to overloading and shock loading.

Accurate Weighing

A 50 lb capacity industrial scale that delivers accurate weight readings within .01 pounds of an object’s true weight is considered an accurate scale. The average Strain Gage scale offers consumers readability of .01 pounds, but for a number of weighing applications, consumers require a scale that can deliver weight readings that are more accurate than .01 pounds.

Before Arlyn Scales’ Ultra Precision, the go-to scales for extreme accuracy were Magnetic Force Restoration scales. The problem with MFR scales, however, is they are only practical with maximum capacities of up to about 25 pounds. Ultra Precision Scales offer consumers weight readings that are within .0005pounds of objects’ true weights and can be made with maximum capacities up to 1,000 pounds. As a result, they are the best scale option for weighing applications that require extreme accuracy.
