Analogue Vs Digital Load Cell – Which One Is Your Best Bet?

To gauge the performance of a weighing machine, we scrutinise every component of it. From the professional design and robust indicator to versatile connectivity, we check them all before making a purchase decision. But, of all components, checking the load cell is of utmost importance. After all, it is the load cell that determines the accuracy and precision of your weighing machine. Now, it’s on you to pick between analogue or digital load cell for your scale. Can’t decide which one you should go for? In this blog, we delve into a comparison and discuss some parameters to help you take the right pick. So, keep reading and find your best choice.


 Strength of signals – When you use analogue load cells, the analogue to digital conversion occurs at the indicator. However, in digital load cells, strain gauge signals transform into digital signals using an A/D processor. The analogue range in analogue scale is prone to greater fluctuations, whereas, the signal range of a digital scale is steadier and gives a stronger signal reading. So, when it comes to weighing accuracy, a digital load cell is a clear winner in this category.

Content of signals – Analogue scales use the electrical voltage of the analogue load cell, but digital scales utilise data transmitted from the digital load cell. And as this transmission of data is the result of using a binary language, it is resistant to the interference from temperature, radio signals, electromagnetism, and so on. Consequently, digital load cells are much more reliable in offering a stable weighing result than an analogue scale.

 

Upfront cost and affordability – If you take the upfront cost into account, then buying an analogue scale might sound more appealing. However, we suggest investing in a digital load cell if you are eyeing long term serviceability and high-end performance. There is no denying that digital systems are more expensive to be set up, but they are less prone to breaking down and come with several advanced capabilities. This means you’ll not have to incur regular costs on maintenance or repair.

 

Hassle of calibration – To ensure the accuracy of a weighing scale, it is a must that the load cell is properly calibrated. Do you know digital load cells come pre-calibrated from the manufacturer itself? That’s right! But when you buy an analogue load cell, you need to arrange for calibration all by yourself. Doesn’t that seem like a lot of hassle? We know your answer. Hence, we strongly suggest our customers go for digital scales and avoid the trouble of conducting field calibration.

 

Versatile features – Integrated with additional features, digital load cells are surely more impressive and functional than the analogue ones. Not only are they hermetically sealed, but these load cells boast of a compact design, strong cabling, heavy weighing capacity and high IP ratings. And if you purchase from a top brand, you can get your hands on OIML/NTEP approved load cells. That way, you can count on accurate and efficient weighing operations always.

 

Conclusion – To gain a competitive edge over your contenders in the market, you should give up on tradition weighing equipment and start using a digital load cell and weighing scale. With an array of collection, HiWEIGH serves as the one-stop-shop of your weighing requirements. If you want to place an order, get in touch with the team now.

What Causes a Load Cell to Malfunction?

Load cells are at the heart of every weighing operation. A digital load cell is the most crucial component in most of the weighing scales used today. From a simple bathroom scale to advanced weighbridge systems, load cells determine the weight of any item placed on these scales.  They convert the mechanical force put by a load into electrical output to display it on the weighing indicator. Thus, without a working load cell, weighing scales would show inaccurate readings. No matter what the industry or application is, be it a crane scale manufacturer or retail scale manufacturer, load cells are essential for the functionality of all types of weighing scales. But at the same time, a load cell can also be very vulnerable. In this blog, we look at a few common causes that can disrupt the working of a load cell. Overloading Capacity Load cells can get damaged due to the overloading of a weighing scale. All scales in the market come with a maximum loading capacity. The load cells...
