Having a scale is something not many consider, but it can save you a considerable hassle. If you plan on having a business (especially one related to food and consumables), then having a digital scale becomes a necessity. And the beer brewing business is serious business.
However, as with any product on the market today, you don't need just any scale.
Not only do they vary in quality, you can also use digital scales for different purposes. The one you need depends on how you'll use it.
Are you planning on getting one? Read below to know what to look for.
What is a digital scale?
Used for measuring weight, digital scales give you a reading on how much it weighs on a digital screen.
Scales were previously mechanical, and came with small pieces of iron or any other heavy material all to balance the scale.
When the original weight offset, you got the result depending on where you left the iron parts. Digital scales today remove all of that. You only need to place the item you want after programming it on a computer, and the weigh displays automatically.
The only parts you need are the scale and a computer, and sometimes, the latter is unnecessary!
Components of a digital scale
- Load cell transducer
The central part of a digital scale, it senses whenever you apply pressure on it. It then produces the output signal that's proportional to the placed weight. Load cells sensors aren't exclusively transducers, yet all transducers are sensors.
While a sensor detects physical phenomena for producing a change, transducers translate these phenomena into an electrical output signal.
Load cells come in many types, and the most common for digital scales are the strain gauge kind. They come with an elastic metal material fixed to the parts that bend.
- Signal conditioner
While the previous component created the signal, this device amplifies it so that it reaches a readable level. The load cell output tends to be small, and it usually reads in mini-volts.
The signal conditioner increases this output through an instrumentation amplifier. Without this part, the first signal produced wouldn't be enough for the scale to read it.
Together with the amplifier, there's also a filter circuit. The signal conditioner has a second function; it filters the output and input signals.
This filter circuit works to remove the EMI (electromagnetic interference) that could interfere with the signal and its reading. It does so my decoupling AC signals from their DC output counterpart.
We can define a microcontroller easily by saying it's the CPU (central processing unit) on a digital scale.
The signal conditioner produces an output signal that goes into the microcontroller's input port. It takes care of converting it from an analogue to a digital signal. After doing so, the microcontroller reads the digital pulses produced by the conditioner, and it processes them for determining the weight.
After everything finishes, the CPU computes the result and displays it on the LCD screen. Sometimes, the process is shorter; some signal conditioners convert the analogue signal before sending it.
- LCD screen
This component is simply an LCD screen located on the front side of the digital scale. It's connected to the microcontroller, and once it produces a result, the screen displays it with the usual numbers and units.
Different screens work in different ways. Some show you the result only, but others may contain additional information like other weight units.
Factors to consider before buying one
The first factor you should consider before purchasing a digital scale is how you're going to use it.
If you're using it for a supermarket or any store focused on selling consumables, you won't need an industrial scale. As a general rule of thumb, you want the most straightforward scale your business can use.
Additional details include how easy it is to store the scale or how heavy are the objects you're going to weight.
The scale a doctor uses isn't the same one your local grocery store clerk uses. Likewise, a large manufacture plant needs a tool that's entirely different for the other two's necessities.
Closely tied to the previous factor, we have how much weight it can handle. It's easy to think of buying the scale with the highest measurements, but there's more to it.
First off, scales with lower capacity tend to cost less, so you may save some money by knowing how much you're regularly measuring. Another significant consideration is how much extra weight you can place before it damages.
Some scales have safety measures that prevent damage when you place additional weight.
Why would you purchase a scale that you can't read properly? Of course, you want to read your results without forcing your eyes too much.
However, readability goes further. It also relates to how many decimal numbers it can display. That's when it becomes essential (again) to know how much capacity you need.
You see, larger scales tend to skip more decimals for favouring larger weights. Yet, when you're working at a pharmacy or with very light products, you require those extra decimals.
Another reason to consider this is money. Depending on how small are the weights you're handling, you may need more expensive models. This last type of scale is also unfit for industrial environments, so make sure you're buying the right scale.
As mentioned earlier, you'll like have to use your digital scale with a computer. Other external devices you may need include printers or other devices for increasing quality control and tracking processes.
Older digital scales are exclusive for weighing. However, modern models include several and different integrations, like Wi-Fi connectivity and USB ports.
Some scales even support advanced connections with equipment that enhances its inherent function. These integrations include tools for controlling how the output lines act with specific processes.
There aren't many reasons for settling with a standard, weigh-only product.
- Special modes
This factor is closely related to the connectivity issue. You may want a scale for weighing your products and nothing more. However, you can find scales that support counting for parts, dynamic weighing, and a list of other functions.
If you need so, you'll have to look for a scale with the required software for these additional features.
Other features you may need in your working day include data accumulation or display hold. All of these additional functions are something to keep in mind.
If you're keeping an inventory, you may prefer to get a scale with data accumulation that can also count parts. Think about how much time you can save with some of these additional features before getting your digital scale.

You may need a scale for cooking, or you may need it for measuring a package before sending it. There are many uses for digital scales, and there are many kinds of scales for each one.
You must know how you're going to use it and why you need the scale. There's no reason to purchase a scale with a maximum capacity of over 100kg if you only need it for cooking. Likewise, you'll probably break a small kitchen scale if you use it for weighing someone.
Knowing the size you need and what functions are essential is the best way to save money. Don't purchase a scale with features you'll never use if you want to lower expenses, and don't settle for a primary tool if you need an advanced scale.
