POWERCELL^® PDX^® load cells have set a new standard for accuracy and reliability in vehicle scales. Since their introduction in 2009, other truck-scale systems have struggled to match their performance. When we take a detailed look at a few of the differences among load cells, it is easy to see why METTLER TOLEDO vehicle-scale load-cell systems are still the most innovative in the industry.

Lightning protection

A lightning strike is the biggest risk to a truck scale, with the capability to inflict extensive damage that requires expensive and time-consuming repairs.

Other load cells

• Include features that may reduce component damage, but rarely offer complete protection
• May promote grounding features, but grounding alone is inadequate
• No independent verification of performance

POWERCELL PDX

• StrikeShield™ active protection system provides complete protection
• Certified by an independent aircraft component lightning laboratory

Hermetically sealed load-cell enclosures

Maintaining a hermetically sealed enclosure for the life of the load cell is critical to scale performance.

Other load cells

• No way to ensure the ongoing integrity of the seal
• Breached enclosures introduce moisture inside the load cell, resulting in weighing errors before cell failure

POWERCELL PDX

• Breach-detection system alerts users immediately if a load cell enclosure is breached
• Scale will operate normally until a technician can investigate the issue during a scheduled service call
• Virtually eliminates unexpected malfunctions

Stainless-steel braided cable protection

Cable damage is a common cause of vehicle-scale problems.

Other load cells

• Single-layer low-grade stainless-steel sheathing
• Fraying and unwinding over time
• Limited protection from rodents and physical damage

POWERCELL PDX

• Double-layer high-grade stainless steel sheathing
• High-quality construction stays tight over time
• Strong protection from rodents and physical damage

Accuracy compensation

Load-cell outputs can be influenced by environmental factors, resulting in hidden weighing errors.

Other load cells

• Those with compensation typically compensate for temperature only
• Universal adjustment often applied equally to all cells with limited precision
• Crudely applied, using resistors in the circuitry that offer limited capabilities

POWERCELL PDX

• Compensates for numerous factors that affect load cells over time, including:
• Temperature
• Metrology
• Hysteresis
• Creep
• Individual adjustment performed on each load cell using exact coefficient values
• Applied digitally, using patented algorithms that are infinitely precise
