from the system.
w
Risk of injury caused by pressure or burns.
u
Ensure that the system is free of pressure during installation.
u
Ensure that no media can leak at the mounting location during installation.
4.1 Use in hygienic areas according to EHEDG
In case welded adapters are used, the food contact surface must be smooth (surface roughness
Ra < 0.8 µm) and the welding has to be done according to EHEDG Guideline 9 and 35.
The sensor is suited for CIP (clean in place) when installed correctly.
u
Observe the application limits (temperature and material resistance) according to the data
sheet.
u
Ensure that the installation of the unit in the system complies with EHEDG.
