  • How Do You Calibrate Truck Scales

    It goes without saying that your truck scales must be calibrated for the most precise measurement possible. And how do you ensure that? By calibrating the scale properly and regularly, of course! Even the slightest error in calibration can result in major losses in revenue and lead to overweight ticketing and fines. This risk increases exponentially if you are weighing several trucks every day.

    To make sure this doesn’t happen to you, follow these tips for truck scale calibration and get the most accurate measurement every time, without fail.

    The Truck Scale Should Be Tested & Certified

    The initial certification is critical when it comes to proper calibration of the truck scale. This certification guarantees that everything is working exactly the way it should and also considers factors like gravity tolerance, scale location, and scale model.

    When your truck scales are installed, make sure they have undergone testing and certification for their performance. While this may sound like an obvious thing, you’d be surprised to know how many new scale owners don’t realize its significance.

    Keep Up With the Indispensable Calibration Tests 

    There are three tests you can perform yourself to check the accuracy of your truck scales: the eccentricity test, repeatability test, and linearity test. The eccentricity test requires you to place the weight on different spots of the scale to ensure an accurate reading every time.

    The repeatability test requires you to add and then remove the same volume of weight onto the scale multiple times in a row, to ensure it is consistent. And in the linearity test, you group different weight sets together to see how the calibration may need to change in case of an error. Please note that there’s much more to truck scale calibration than these three tests and you should schedule periodic calibration from trained professionals.

    Regular Calibration For Optimal Performance

    How often you calibrate your truck scales depends on the scale as well as several other elements like:

    • How many measurements are being made per day
    • How many days the scale is being used
    • How the weather or environment might affect the scale

    Consistency is the key here. By calibrating regularly, you will reduce the risk of external factors affecting the scale’s performance.

    Periodic Cleaning & TLC

    As the old adage goes, when you respect your things, they will respect you back. Proper functioning and accurate measurements rely largely on your treatment of your truck scales. While regular calibration will keep it working correctly, proper and timely maintenance will make sure it lasts a long time.

    This means checking the scales often for dirt, dust, mud, debris, and other signs of wear and tear. Don’t forget to winterize your truck scales and take other measures to protect your investment during extreme temperatures. Even something as seemingly inconsequential as dirt can build up over time and lead to inaccurate measurements. Be sure to spend some time taking good care of your truck scales.

  • Tips For Buying Truck Weight Scale Online

    A truck weight scale goes through a lot. It is exposed to extreme temperatures and is often used in relentless environments. To make sure your scale doesn’t break down in the middle of operations and lasts a long time, you need to invest in a high-quality product that comes with a solid warranty. Here are some of our best tips to help you choose the best truck weight scale to maximize your ROI.

    Check Local Regulations & Laws

    You should be aware of all the laws regarding truck scale standards and usage in your city and state. While all scales should meet the requirements set by the State Weight and Measures Department, your state may have more regulations you should know about.

    Look for Truck Weight Scale Resilience

    Buying a scale that is built and tested in real-world conditions is a must. Find a manufacturer who performs weighbridge tests to test their scales; these tests are designed to imitate real-world scenarios.

    Also, consider these factors:

    • Are load cells protected against lightning strikes? (this should be confirmed by a test conducted by an independent, third-party lab)
    • Do the axle load safety factors surpass the maximum allowed weight on the highway in California (or whichever state you live in)?
    • How many trucks can the scale handle per year?

    Consider Truck Weight Scale Utility and Operation

    When it comes to mode of operation, a scale can either have a system of digital load cells (electronic) or levers (mechanical). Each option has a set of advantages and disadvantages so choose wisely based on your specific application.

    You may want to buy a weighbridge that can be connected to your personal computer so the scale can provide weight reports, print tickets, and do much more. This is just an example; there are many more utility features you may find attractive for your business.

    Review Truck Weight Scale Warranty

    We always recommend comparing warranties before you buy a scale. Look out for any exceptions to the coverage and additional fees. Many manufacturers cover the scale, but will charge you extra for:

    • Time and travel expenses to get to your location to perform repairs/replacement of parts.
    • Labor to replace broken parts.
    • New parts that will be needed for repair.

    All these expenses can really add up, as you can imagine. You should account for the travel time, labor cost, mileage cost, and parts cost when you are looking at the warranty.

    Determine Truck Weight Scale Maintenance Requirements

    Every scale must undergo a recalibration of cells on a regular basis, especially when it is being used heavily. Some scales require more frequent servicing than others so don’t forget to check the periodic maintenance schedule supplied by the manufacturer when you are making comparisons. It’s always best to choose a reliable, authorized distributor who offers calibration and repair too.

  • Laboratory balances are used to measure tissue, liquids, and solids in a wide range of settings, including environmental, clinical, and research labs. To put it simply, a balance is generally used to measure the mass of an object. There are several different types of balances, and each one comes with its own set of features.

    Before you buy a balance, you need to consider:

    • The accuracy you need
    • The maximum capacity you need
    • The application that you need to measure

    Analytical Balance

    Analytical balances are capable of measuring small masses with incredible precision. These balances are typically used in quantitative chemical analysis and can measure 4 decimal places to the right of the decimal point. Since analytical balances are highly sensitive, even an air current can impact the measurements. This is why these scales often come with a draft shield to prevent inaccuracy.

    If you are planning to use analytical balances, make sure you have a dedicated space in order to prevent interference from environmental factors. You will also need to monitor and calibrate these balances frequently. Most analytical balances consist of an automatic, internal, motor-operated calibration weight. You can also use external weights for calibration.

    Precision Balance

    A precision balance is cheaper and less accurate than an analytical one. It can measure up to 200 gm; an analytical balance, on the other hand, can measure up to 320 gm of mass. These balances are also known as top-loading balances and have the readability of up to 3 decimal places to the right of the decimal point. They are extremely quick – a precision balance can give you a read-out within a couple of seconds.

    Unlike analytical balances, precision balances are not affected by the air current or other environmental factors.

    Analytical Balance vs. Precision Balance At A Glance

    FeaturesAnalytical BalancePrecision Balance
       
    AccuracyExtremely accurateNot as accurate
    ReadabilityUp to 4 decimal points to the rightUp to 3 decimal points to the right
    Readability RangeBetween 0.0001g to 0.00001gBetween 1 mg (0.001 g) to 1 g
    Environment Factors (like air current)Can affect the readingHave no effect on the reading
    CostExpensiveLess expensive

    If you want maximum accuracy, an analytical balance is the best option since it can provide the accuracy of 0.0001 to 0.00001g. But if you don’t need exact accuracy at small levels, a precision balance could be a good option instead.
