Schedule
 EQUIPMENT:
Equipment and systems covered by this certificate are as follows
 
 

The load cell type series SKL-XXD-Y Z_ATEX work on the principle of transverse shear force measurement to the longitudinal axis and are operated on hydraulic cylinders of working platforms, cranes and conveyor systems in hazardous areas. The load cell can be configured with either one or two measurement channels 

The maximum permissible ambient temperature range is shown in the following table:

 
 ambient temperature range marking
 -20°C up to +60°C Ex ia IIB T4
 -30°C up to +80°C used as Ex ia IIB  T4  Gb-equipment
 -30°C up to +80°C Ex ia IIIB T120°C

For applications requiring EPL-Ga equipment, the media process pressure has to be between 0.8 bar and 1.1 bar.
If there is a deviation from the above mentioned conditions it should be noted that the load cell has a temperature rise of max. 29 K and the safe operation of the installation in terms of pressure / temperatures of the used materials shall be guaranteed by the user. Here, the characteristics specified by the manufacturer shall be observed
