Product Description

Compression Type Digital Load Cell

The type RC3D is the digital version of the successful RC3 rocker column load cell. An integrated state of the art microprocessor system within the load cell improves system accuracy and load cell handling. The digital output enables the user to communicate with each load cell independently from others.

Key Features

  • Capacities of 30, 40 and 50 t
  • Stainless steel construction
  • Environmental Protection IP68 with complete hermetic sealing
  • Self-restoring design
  • Digital load cell with built-in microcontroller and A/D conversion
  • Easy communication (RS485) and fast system setup
  • Improved handling of corner adjustment, system calibration, fault finding and load cell replacement

Approvals

  • OIML approval to C3 and C4 (Y = 15 000)

Application

  • Weighbridges, hoppers, tanks and silos

Packed Weight

  • Capacity (t) 30 40 50
  • Weight (kg) 3.3 3.6 4.5

Option
