Performance highlights CA Low profile donut ring load cell (ATEX)

The CA Anchor Load Cell delivers reliable and precise force measurement in demanding industrial applications. With capacities from 30,000 kg to 250,000 kg, it offers a compact yet rugged solution for critical anchor and structural monitoring.

Usage conditions

Built with 17-4 PH stainless steel, the CA is corrosion-resistant and certified to IP68, making it suitable for outdoor, marine, and underground use. The sensor remains stable over a wide temperature range (-20 °C to +70 °C) with low creep and excellent zero balance.

Possible applications

  • Anchor load monitoring in tunnels and dams
  • Structural testing and monitoring
  • Industrial press force measurement
  • Foundation and pile testing
  • Harsh environment load control

Advantages of choosing this product

Its low-profile donut-ring shape and internal bore make the CA ideal for fitting around anchor rods, bolts, or cables without altering the structure. Optional ATEX and redundant bridge configurations ensure added safety in hazardous zones.

Other important features

  • Rated output: 2 mV/V ± 0.1%
  • Zero balance: ±1%
  • Insulation resistance: >5000 MΩ
  • Ultimate overload: 300%
  • Shielded 5m cable with 4-core wiring
