Lightning strikes are one of the most common difficulties that can affect a truck scale.
SmartCell® digital load cells provide superior protection that protects against electrical
uncertainties.

• Truck scales, due to their composition and size, are a magnet for attracting lightning. Many times, these scales are placed in an outdoor area that is exposed to the elements. The main front of protection against lightning strikes and power surges lies in the junction box. Unfortunately, if the junction box is compromised it can cause damage to the whole load cell weighing system. One or more of the load cells can be damaged in a traditional load cell arrangement, which can come at a great cost.

• The gas discharging tubes that divert excess voltage from lightning and power surges are normally placed inside the summing box of analog load cell systems. Cardinal’s SmartCell® digital load cells have the apparatus of discharging excess voltage placed in each load cell. This ability for each load cell to individually protect itself provides another line of protection for the whole load cell system. If a lightning strike or power surge happens, one load cell has the capability of preventing damaging surges from
passing onto other load cells.

• Unfortunately, lightning strikes and power surges are commonplace. These occurrences have the potential to wreak havoc on truck scale electronics. Luckily,
Cardinal’s SmartCell® digital load cells can protect individual load cells and the
entire load cell system from excessive damage caused by freak electrical incidents.

• If you’ve experienced reoccurring problems with damaged load cells and repairs caused by lightning and power surges, SmartCell® digital load cells can help protect your truck scale electronics against severe damage.
