Cold, hard facts are vital when considering a new scale. To make an informed decision, you need to know about technology and specification options. It’s important to cut through the fluff of sales material and get down to the details of the product.
Here are some things to consider in a truck scale.
How a Truck Scale Works
A truck scale is used to weigh an entire truck and should be long enough to fit all wheels of the longest truck you plan on using.
Each truck scale consists of 5 main components: foundation, weighbridge (or scale deck/driving surface for the trucks), load cells (sensors which measure the weight on the scale), terminal (indicator or control panel), and cables.
Lifespan of a Truck Scale
While several factors can affect the life of a truck scale, they typically last 10-20 years. It is important to consider the manufacturing quality as they vary greatly. Environmental factors and the rate of use are also things to consider. Scales weighing 400 trucks a day will wear more quickly than those weighing 40 trucks a day.
Truck Scale Accuracy
Precise weighing can impact the bottom line as well as inventory levels, and management quality. There is a legal accuracy tolerance depending on the particular scale and its function within each region that recognizes NIST/NTEP, OIML or other standards. For example, a scale that has the capability of weighing 200,000 pounds and is weighing trucks that are 70,000 – 80,000 pounds, has a 160 pound of error (positive or negative).
Truck Scale Calibration
An important fact to determine when considering how often to calibrate a scale is how many trucks per day will be weighed on the scale. High demands and heavy volume will affect the scale’s accuracy to go beyond tolerance levels faster. Most legal – for – trade applications require the scale to have a certification of compliance from local weights and measures authorities either annually, or semi-annually.
Temperatures and other environmental factors will also affect a truck scales calibration. Subtle changes over time can cause a negative impact on a scale.
It can be costly to replace a scale altogether. When experiencing frequent repairs or downtime, especially for newer scales, most issues can be traced back to the load cell system. Consider upgrading the load cell system to improve function and accuracy.
If you are considering a new truck scale, be sure to look at the specifics and how they relate to your particular needs. With so many variables like environmental factors and frequency of use, it is important to make an informed decision that will serve you and your company for the long run.
