Position: This article describes a Truck scale load cell system used in harsh weighing environments which is manufactured METTLER TOLEDO company.
Offered as digital load cell for truck scale applications, POWERCELL(TM) PDX(TM) features self-monitoring capability that proactively helps avoid unplanned downtime and inaccurate weighing. These truck scales can be connected together in series, eliminating need for junction box. Cables use submersible quick-disconnect connectors that provide IP68/IP69k seal, and protection against lightning damage is delivered via StrikeShield(TM) system.
New Load Cell System Revolutionizes Vehicle Weighing
METTLER TOLEDO continues to be the innovation leader in truck and rail scales with the introduction of the new POWERCELL(TM) PDX(TM) load cell system. Truck scale failures and unplanned repair costs can be virtually eliminated with the use of this new load cell technology coupled with regular maintenance.
The legacy continues
Back in 1988, METTLER TOLEDO introduced the POWERCELL load cell, the first digital load cell for truck scale applications. The innovations in POWERCELL were like none other in the industry. It provided accuracy and reliability beyond all other methods available for the harsh environments where truck scales are required.
The POWERCELL PDX load cell system is the latest generation of the POWERCELL legacy. The innovations provide another leap forward in reliability while maintaining the best accuracy in the industry and offering the security of predictive diagnostics.
No more junction box wiring
Prior to the introduction of POWERCELL PDX, all load cell weighing systems required junction boxes to bring together all of the weighing signals and transmit them to the controller. These boxes are wired at the construction site and are exposed to the weather. The process is riddled with potential errors and is the most common source of truck and rail scale failures. POWERCELL PDX load cells are connected together in series so that no junction box is required. The cables use submersible quick-disconnect connectors that provide an IP68 and IP69k seal. The entire network is a sealed system from the controller in the scale house out to all of the load cells in the scale.
Unmatched lightning protection
A lightning strike can put a truck scale out of service in an instant. Lightning damage can be very costly, requiring the replacement of unprotected electronic equipment. Even if a warranty covers repair costs, you still face the cost of the business you lose every day that your weighing scale is not operating.
METTLER TOLEDO provides complete protection against lightning damage. The StrikeShield(TM) protection system is designed to be the main line of defense for your entire truck scale system: load cells, cables, and weighing controllers. The average lightning strike is approximately 30,000 amperes. The POWERCELL PDX load cell system has been proven in independent testing to survive multiple lightning strikes up to 80,000 amperes. That's more than twice the destructive power of the average lightning strike. No other scale manufacturer has had its system as thoroughly tested by independent laboratories.
Predictive diagnostics
With other load cell technologies, problems can go undetected for long periods. In those cases, weighing errors add up until a load cell fails and shuts down your scale. The POWERCELL PDX load cell eliminates these concerns. The system has self-monitoring capability that is designed for proactive service, alerting you to potential problems before they occur. It helps you avoid unplanned downtime and inaccurate weighing. If these occur the diagnostic tools enable service technicians to make the right repairs the first time and make them quickly.
The truck scale system provides you with a proactive way to keep your scale running:
# Assuring you that your scale is working properly.
# Alerting you to potential problems so they can be prevented.
# Pinpointing the source of a problem for quick intervention.
Proactive maintenance plans perfectly complement the POWERCELL PDX load cell system to deliver unmatched reliability and longevity for your scale.
