It is probably a good idea to have your heavy capacityÂ truck scalesÂ checked at least every six months at a minimum. Also, a convenient time to conduct a preventative maintenance scale inspection is during the regularly scheduled calibration check.Â Itâ€™s a good idea to inspect your truck scale just prior to peak usage times, such as harvest season in agricultural operations.

Cardinal Truck Scale Manufacturing
Cardinal Scale’s truck scale manufacturing processes was featured in a Fall 2008 episode of cable TV’s popular program “How It’s Made” airing on the Science Channel. The segment details the production of a 70-foot-long electronic Cardinal truck scale. Beginning on a microscopic level with the creation of the strain gauges that reside in the scale’s load cells, the educational program charts the manufacturing course of a Cardinal model EPR truck scale. It proceeds to show the welding processes involved in the steel tubing and load cell stands, the powder paint process, and final assembly where the finished truck scale is shown with test weights being applied to measure its superb accuracy.
The episode first aired in November 2008 and will be translated into over 3 dozen different languages to be shown internationally. One of the reasons Cardinal was asked to participate on the show was worldwide brand name Continue reading
Programmable Digital Weight Indicator for Truck Scales
HMI Digital Weight Indicators from Rice Lake Weighing Systems, offer a complete line of weight indicators to fit any application. The revolutionary Rice Lake 920iÂ® programmable HMI Indicator/Controller takes charge of process applications and provides open connectivity to the most popular networking interfaces. When used in batching / mixing applications, one 920i indicator is capable of handling multiple scales, flow, temperature and pulse. It can control hundreds of I/O set points, queue gates and conveyors, perform yield management functions and store, Continue reading
What is concentrated load capacity and ntep?
Concentrated Load Capacity, or CLC, is an industry recognized rating of a vehicle or axle load scale. The rating defines the maximum load for which the weighbridge is designed as applied by a group of two axles with a center line spaced 4 feet apart and an axle width 8 feet apart. When a CLC load is applied to the weighbridge during a National Type Evaluation Program test, the NTEP tester records the displayed weight. If the scale falls within accepted testing tolerances, the scale has that CLC weight value recorded as the CLC on the Certificate of Conformance.
The CLC rating is not a measure of weighbridge strength or rigidity, because weighbridge deflection is not measured in the NTEP test. It is irrelevant if the load weighbridge sags 1/10th of an inch, or 10 inches, as long as the scale weighs within the accepted tolerance. The scaleâ€™s CLC weight rating passes in either case. A high CLC rating could be given to an extremely flexible deck sitting on load cell mounts which are capable of accurately handling the side loading resulting from a severely sagging weighbridge.
The Rice Lake SURVIVORÂ® truck scale line boasts a 45 ton (90,000 pounds) CLC rating. With most legal highway weight limits being a fraction of Rice Lake’s rating, owners of a SURVIVOR scale can expect a long lifespan through Continue reading
