What Does a Counting Scale Do?

When you’re seeking solutions for increased efficiency and productivity. A counting scale can be a great choice. But, what exactly does a counting scale do?

We’re going to take a look at what a counting scale actually does

First, let’s define what a counting scale is. Counting scales are used for counting the same items, like bolts for example. As for how to use a counting scale, when a group of identical items are placed on the platform of a parts counting scale, the scale can determine the average piece weight and the scale display shows how many pieces are on the platform. Consider the human effort involved to count small items like screws or washers.

With a counting scale, this task requires just a few seconds of time. This leads to highly accurate parts counting results. Compare this to counting parts out by hand, which is virtually guaranteed to include human error. Remember when you were a child sitting on the floor counting pennies? It took time, and then even more time when you lost count and had to start over again! Consider a counting scale the industrial solution for saving time while providing extremely efficient counting accuracy. Continue reading

Should I Buy a 4×4 or 5×5 Scale for Weighing a Pallet?

Today we attempt to answer the question that many a purchasing agent or warehouse manager has surely pondered….

Should I buy a 4×4 or a 5×5 floor scale?

Have you ever gone looking for a simple floor scale to weigh pallets? Only to be confused by whether you need a 5×5 or a 4×4 model. You’re not alone. There are many before you that have had the same question or something similar. It may have been about low price floor scales online or possibly about pallet scale calibration or scale troubleshooting. These are all platform scale subjects we have covered many times on this website. But getting back to the main point, should you buy a platform scale that’s 48″ x 48″ or 60″ x 60″?

This article is meant to provide a brief comparison while giving you confidence to make the correct decision when shopping for a standard industrial floor scale. While the 4×4 floor scale is actually the most common scale purchased, the 5×5 has a slight advantage of being able to, accommodate the full length of a pallet jack without fear of rolling off the back of the scale.


Which Scale is Better for me?  5×5 or 4×4

As we say, with truck scales, trucks aren’t getting any shorter, and pallets, by the same token, aren’t getting any smaller. So, if you have the room in your warehouse, then you should strongly consider the 5×5 pallet scale. With the exception of the additional surface area and the additional cost of the 5×5 floor scale. These two scales are identical from most manufacturers. One exception would be since the 4×4 floor scales are often mass produced, Manufacturers may try to use a thinner deck plate that is more widely available. This naturally makes the mass produced scale less durable and exposed to more deflection of the weighbridge and that could possibly lead to more inconsistent weights and possibly even a shorter lifespan. Although they are less common, another consideration that might make sense for you would be a 5×4 scale.

4 Foot Long Scale Ramp is Recommended for a Pallet Jack

And don’t forget if you’re looking to roll a pallet jack onto the scale, then you will need to have enough space for a ramp for pallet jack use. Most scale manufacturers recommend a four foot long ramp. So you will want to make sure you have the floor space for a 5×5 scale and a 5×4 ramp as well.

Truck Scale Basics & Terminology You Need to Know

We’re going to try & help you understand all the truck scale terminology that you need to know. Especially if you’re new to truck scales.

So let’s say your business has decided to purchase a truck scale in order to determine accurate and reliable vehicle weight for your application. That’s great! Understanding fundamental truck scale basics and how a truck scale works will help you know which questions to ask your local scale distributor to ensure you purchase the truck scale style that fits your needs with the options and accessories that can enhance your application.


Whether monitoring a vehicle’s weight for safety guidelines or to complete business transactions, you should know what the info determined by a truck scale means to your business.

For example:

Gross weight is the total weight of the vehicle and loaded product.
Tare weight is the weight of only the vehicle.
Net weight is the weight of only the loaded product.

Today, most scales at solid waste facilities or recycling centers are installed with above ground or concrete pit foundations. Depending on state or regional requirements, scales can also be installed in a shallow pit, as opposed to the deep pit required by older mechanical scales. A pit installation requires less space than an above ground scale since longer approaches are generally required for above ground configurations. However, pit-styles require sump pumps and drains, and are generally more vulnerable to corrosion due to potential standing water.

The truck scale’s driving surface is called the weighbridge. Weighbridges are composed of steel or concrete decks, and are typically manufactured in modular designs that are connected together during installation.

weight indicator

The indicator, also called a controller, or terminal, can display basic weight functions, as well as serve as the command center for a weighing system with truck in & out programs to control the entire truck scale system, including any remote displays and ticket printers.

Load cells are vital to truck scale performance. There are various types of load cells, but they all basically have the same function—to accurately measure weight on the scale. How do load cells work, you may be asking?  All load cells take an analog measurement, and then that signal is converted to a digital output either at the load cell, junction box, or in the scale indicator. Load cells are typically constructed of steel and are integrated within the weighbridge, usually at the corners of each module.

A junction box properly manages multiple load cells. By matching the signal of each load cell and summing them into a signal that’s sent to the indicator, junction boxes equalize the system for accurate and reliable weight readouts.

Handwriting a ticket for each weighment is time consuming and tedious, and also leaves room for human error. Ticketing kiosks, scale data management software, and/or ticket printers eliminate those problems. Most states also require ticket printers and Remote Displays.

We’re going to wrap up our entry on truck scale basics and terminology.  I hope we made all this truck scale jargon a little easier to understand for those of you in the market for a truck scale.

Load Cell Wiring & Adjusting / Trimming / Summing Overview

The Basics of Load Cell Wiring and Trimming Load cell wiring and trimming are critical to a weighing system’s accuracy and should always be performed by trained scale technicians.

However, general load cell wiring knowledge can help you better understand how your weighing system works and how potential errors occur.

Load cell cables typically have four or six wires. Both versions have positive and negative signal and excitation lines, though a six-wire cable also has positive and negative sense lines. Sense lines are linked to the sense connections of the system’s indicator, sometimes through a junction box, allowing the indicator to sense a load cell’s actual voltage. If there is a voltage drop between the indicator and load cell, the sense lines send that information to the indicator, which automatically adjusts voltage. This compensates for the loss of voltage or amplifies the return signal to compensate for loss of power to the load cell.

Load Cell Color Codes

Load cell wires are color coded to help ensure proper connections. Different load cell brands use different color codes, which is why there are load cell wiring guides available for scale technicians to use during installations.

Adjusting / Trimming / Summing Load Cells

Load cell trimming is sometimes called load cell summing because it involves tying or summing multiple load cell output signals together. This happens in a junction box, also known as a summing box, which sends one system signal to the weight indicator. It’s necessary to trim load cells in a multi-cell system when the weight distribution to each load cell isn’t equal. Click the following link for more about how a load cell works.

For example, in vessel loading processes, the presence of agitators or the type of material, such as powder, can affect how material and weight are distributed to each load cell. Additionally, it’s nearly impossible to make every load cell exactly alike. Tolerances in the manufacturing process allow for some variation in individual load cell specifications, which, if trimming isn’t applied, doesn’t allow for the accuracy necessary for most applications.

Signal trimming is the most common and popular type of load cell trimming because it is the easiest to use. Signal trimming is compatible with nearly all indicators and is relatively unaffected by temperature changes or excessive system vibrations. It involves adding a relatively high parallel resistance between the signal of each load cell, which creates a leakage path that diverts some of the available load cell signal away from the indicator. More load cell signal will be available to the indicator as parallel resistance increases.
