Industrial Scales And Their Types

An industrial scale is a type of weighing equipment designed for heavy-duty applications in various industries such as manufacturing, logistics, agriculture, and retail. These scales come in different types, including platform scales, bench scales, and truck scales, each tailored for specific tasks. They are commonly used in factories, warehouses, and logistics depots to accurately weigh large items and ensure efficient operations. 

Not all scales are built for the same purpose. Using a bench scale for pallets will break it. Using a truck scale for small parts wastes money.

• Bench Scales sit on workbenches and handle packages, ingredients, or parts up to a few hundred pounds. Perfect for shipping, food prep, and quality control.
• Floor Scales are larger platforms for pallets, drums, and carts. Built for warehouses and manufacturing. They handle hundreds to thousands of pounds.
• Truck Scales weigh entire vehicles at ground level or in pits. Essential for logistics, recycling, and agriculture.
• Portable Industrial Scales move where you need them. Instead of bringing items to the scale, you bring the scale to the items.
• Counting Scales calculate quantities based on sample weights. You weigh a sample, and the scale counts thousands of parts automatically.
• Crane Scales suspend and weigh items from above. Used in construction and heavy manufacturing, where items can't sit on platforms.

Most modern industrial digital scales use electronic load cells. They're accurate, reliable, and offer data storage and connectivity.

Choosing The Right Type of Scales for Your Business

Three out of four companies choose the wrong scale the first time. They replace it within eighteen months. You must look for the following key features when buying one

1. Capacity

What's your heaviest item? Add buffer. A scale loaded near maximum wears out faster. If your heaviest load is eight thousand pounds, don't buy a five-thousand-pound scale.

2. Accuracy

The accuracy of industrial weighing systems matters the most because some sectors demand it. For pharmaceuticals, the production requires accuracy to the gram. Greater accuracy is more expensive, whereas inaccuracy is yet more expensive.

3. Environment

Will the scale be placed in a warehouse where the environment is clean or close to water and chemicals? Performance is influenced by temperature changes, moisture, dust, and vibration. Scales of increased IP rating are more resistant to damage.

4. Connectivity

The latest industrial weighing systems are connected to the inventory software, printers, and databases. This lowers the number of errors in manual entry and accelerates operations.

5. Compliance

In case you do sell by weight or make use of scales in commercial dealings, you should be legally-for-trade certified. There are huge fines that may be imposed for using non-certified scales.

6. Portability

Fixed scales offer stability and higher capacity. Portable options provide flexibility. Consider your workflow.

Don't choose on price alone. A cheap scale that breaks costs more than a quality scale that lasts.

Top Mistakes to Avoid When Buying an Industrial Scale

Here are the top things to watch out for:

1. Buying on price alone: Cheap scales break faster, lose calibration quicker, and lack support. Calculate the total cost of ownership.
2. Underestimating capacity: Add twenty to thirty percent buffer above your heaviest expected weight.
3. Ignoring environment: Standard scales fail in harsh conditions. Match the scale to its working environment.
4. Overlooking legal requirements: If money changes hands based on weight, you need NTEP certification.
5. Forgetting connectivity: Verify compatibility with your systems before buying.
6. Skipping warranty review: Check coverage duration, what's included, and who pays shipping.
7. Choosing the wrong type: Match the scale type to your actual weighing tasks.
8. Neglecting training: Ensure your supplier provides setup assistance and technical support.
9. Forgetting installation: Plan installation logistics before the scale arrives.
10. Ignoring calibration costs: Some scales require expensive professional service. Factor this into your budget.

When buying an industrial scale, it’s important to avoid common mistakes that can cost you time and money. 

Troubleshooting Guide for Industrial Scale Fails

When the power source does not start on an industrial scale, make sure that the power source, the cord, batteries, the fuse, and the breakers are checked. In the case of error codes, consult the manual. To eliminate inaccurate readings, one can correct the scale by cleaning it and recalibrating it with certified weights, and making sure that the scale is in a level position and there are no interferences.

In case the scale is not going to stabilize, eliminate vibrations and prevent air currents. Weight reading zero might involve the removal of shipping screws and load cell checking. Seek professional advice in case of continuing problems or damage to load cells or electronics. Routine cleaning will serve to avoid major problems and maintain the scale correctly.

Certified Industrial Scale Calibration Checklist

Calibration keeps your scale honest. Without it, accuracy drifts, inventory gets miscounted, and shipments get rejected.

1. Determine Need: Watch for signs like zero not changing when you add weight, display fluctuating wildly, or known weights showing incorrect readings.
2. Prepare Environment: Stable temperature, no vibrations, no air currents. Level surface. Clean debris from under the platform.
3. Select Calibration Weights: Use certified test weights only. Most scales need weights equal to at least twelve percent of capacity. Never use random objects.
4. Access Calibration Mode: Navigate to your indicator's setup menu. Look for "Platform Setup" or "Span Calibration."
5. Zero the Scale: With nothing on the platform, ensure the display reads zero. This sets the baseline.
6. Apply Test Weights: Place certified weights systematically. Start low and work up. The scale should display exact weight values.
7. Adjust and Verify: Input correction factors through the indicator. Remove and reapply weights to verify. Test at multiple capacity points. Perform corner tests.
8. Legal-for-trade calibration: Only certified technicians can calibrate scales for commercial transactions. They use state-approved weights and provide documentation.

Calibration frequency depends on usage. Heavy-use scales in demanding environments need monthly calibration. Light-use scales might go quarterly.

Maintenance Steps Playbook for Industrial Scales

These maintenance steps extend the life of industrial weighing solutions, reduce breakdowns, inaccurate readings, and emergency repairs.

1. Preventive Maintenance

Look at your scale every day to confirm that it has not been damaged and remove any debris, ensure that the display is on, and that it is at zero. Test weekly using known weights and check cables and mounting hardware. 

Clean thoroughly once a month and inspect load cells for cracks or corrosion, ensure it is on its level, and tighten bolts. Get it calibrated regularly by a professional every few months, clean hard-to-reach areas, change worn-out components, and upgrade the software. This is a basic routine that helps keep your scale on track.

2. Predictive Maintenance

Watch for warning signs:

• Readings drift after zeroing
• Display flickers or shows incomplete digits
• Scale takes longer to stabilize
• Unusual noises during weighing
• Error codes appear frequently
• Corners show different readings

3. Corrective Maintenance

Test the power and connections, check the outlet, and check on the damaged cords or dead batteries. Wash the scale and clean the debris off. Do not keep it on an uneven surface; ensure the load cells are not broken. 

Be aware of moisture, vibrations, and extreme temperatures. Any exposure to water should be dry, and all connections tightened so that the scale can work well and accurately.

Everything to Ensure Industrial Scale Compliance

Compliance protects your business. Violations lead to fines and legal problems.
