• Please check for all applications that the product materials (see Technical data)
are compatible with the media to be measured.
• Use in gases at pressures > 25 bar only after contacting the manufacturer ifm.
• High-pressure units (400 bar) are supplied with an integrated damping device
to avoid any risk of injury in case of bursting when bursting pressure is excee-
ded.
Any manipulation of the damping device is not permissible.
When the damping device is removed, there is no damping function
any more. ATTENTION: risk of injury!
