ATEX Version

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÷+40ºC) TX (Ta -20÷+65ºC)
ATEX II 1D tD A20 TXºC (Ta -20÷+40ºC) TXºC (Ta -20÷+65ºC).

The certificate includes the manual and the ATEX CE conformity declaration (available in EN, DE, FR, and IT).

The CCATEX certificate is issued after the checks done by qualified technicians, with the help of specific equipments, for each load cell.

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.
