RCA LOAD CELL: INSTALLATION KIT
  • The KRCA kit allows a correct installation of the RCA load cells below the weighbridge plate
  • The kit consists of an upper cup with anti-rotation system, a lower cup and a two-hole plate for easier and faster fixing. All components are made from nickel-plated steel.
  • Both cups are designed for optimal operation in conjunction with the cell’s self-centring spherical bases, allowing their proper oscillation and return to position.
  • The cups are also fitted with triple function integrated washers:
    - they keep lubricating grease in its place.
    - they simplify the proper positioning and levelling of the cell and support it during installation/maintenance.
    - they protect the system by preventing dirt and water from accumulating on the bottom of the cup, thus maintaining the correct oscillation and mechanical compensation of the load cells over time.
Analogue version of compression load cells, ideal for CE-M approved weighbridges, tanks, silos, etc. Manufactured in STAINLESS STEEL, IP68 protection, 4000 divisions, fitted with “rodent proof” armoured cable.

ATEX VERSION RCA LOAD CELL

  • An ATEX version of the RCA load cell is available for explosive atmospheres.
  • The CCATEX certificate makes the load cell suitable for use in hazardous areas with protection methods according to:
    ATEX II 1G Ex ia IIC T6 (Ta -20÷+40°C) TX (Ta -20÷+65°C) Ga
    ATEX II 1D Ex ta IIIC TX°C (Ta -20÷+40°C) TX°C (Ta -20÷+65°C) Da IP65.
    The certificate includes the manual and the ATEX CE conformity declaration (available in EN, DE, FR, and IT).
  • IMPORTANT: the certificate refers to the single load cell. For systems with more load cells, it is necessary to order one certificate for each load cell.
