COK Cylindrical load cell

Heavy-duty column load cell made of nickel-plated steel for 15,000–50,000 kg compression applications. Supplied with mounting kit included.


Key features

  • Wide capacity range: 15,000 to 50,000 kg
  • Combined error ≤ ±0.02%
  • IP68 protection rating
  • KITCOK mounting accessory included
  • OIML R60 C3 certified
  • Available with ATEX and IECEx certification on request

Performance highlights

The COK Column Load Cell is designed for high-capacity industrial weighing. With a rated output of 2.0 mV/V ±0.1% and a combined error ≤ ±0.02%, it delivers precise results in harsh environments. Nominal loads range from 15,000 to 50,000 kg, certified to OIML R60 C3 (3000 divisions).

Usage conditions

Manufactured in AISI 4340 nickel-plated steel and IP68-rated, the COK load cell resists dust and water intrusion. It functions in wide temperature ranges (-30 °C to +70 °C) and includes lightning protection and a secure anti-rotation mounting system (KITCOK).

Possible applications:

  • Heavy silo and tank weighing
  • Weighbridges and truck scales
  • Industrial force monitoring
  • Bulk material process weighing
  • Certified legal-for-trade weighing systems
  • ATEX or IECEx zone installations (optional)

Advantages of choosing this product

The COK series combines mechanical robustness, precision, and convenience. Each unit is delivered with a KITCOK mounting kit, including anti-rotation pin, rubber seal, and self-centering cylindrical plates, ensuring secure installation and minimal drift. Certifications for explosive environments and international trade compliance are available upon request.

Other important features:

  • Safe overload: 150% / Ultimate overload: 250%
  • Compensated temperature range: -10 °C to +40 °C
  • Cable: 20 m, shielded, 6 x 0.22 mm²
  • Easy integration with standard weighing electronics
  • Compatible with VCOKDTL mounting base
