Compression Column Load Cell – ATL501 Analogue

  • Stainless Steel Rocker Column Analog Load cell
  • Self-centering column design with anti-rotation pin
  • 4000 Divisions OIML R60 Class C (C4)
  • Class III L NTEP approved
  • In-built surge arrestors for lightning protection
  • Hermetically welded and sealed to IP68 & IP69K
  • Combined Error < ± 0.013% of Rated Capacity
  • Compensated Temp range of 0 to +50 Deg C(Helps performing best at most demanding climatic conditions)
  • High durability Polyurethane cable (6 core, 18 mtr), provides resistance against harsh weather and aggressive chemicals, and protection against rodents etc.

This stainless steel self-centering rocker column load cell is fully welded and hermetically sealed, with protection to IP68/IP69K. It is an ideal solution for weighbridges/truck scales thanks to its approvals to OIML C4 (4000 divisions) and NTEP Class III L, as well as lightning surge arrestors and a tough, durable polyurethane cable. Corner correction at the junction box is minimised because the ATL501 is pre-corner adjustment optimised at +/- 0.05% by output current calibration (in mV/V/ Ω ). This saves a significant amount of time during commissioning. For use in weighbridges/truck scales, a range of mounting cup accessory sets are available as optional items, in either stainless steel or nickel plated alloy steel, along with a rubber gaiter, sealing clip and a set of centering discs. The ATL501 load cell also has application in silo, vessel and tank weighing, for which the ATL501 Silo Mount version is preferable. For applications in aggressive environments where stress corrosion or acid attack could be an issue, a special Parylene coating can be specified as an option. Also available are ATEX and High Temperature versions. While the ATEX certification allows use in all zones, in dust zones 20, 21, 22 and gas zone 2 there is no need for safety barriers.
