MPa = bar ÷ 10 / kPa = bar × 100
Static and dynamic overpressures exceeding the indicated overload
pressure are to be avoided by taking appropriate measures.
The indicated bursting pressure must not be exceeded. Even if the bur-
sting pressure is exceeded only for a short time, the unit can be destroyed.
NOTE: Risk of injury!
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 exceeded.
When the damping device is removed it can become unusable.
If you have any questions, please contact ifm electronic‘s sales specialists.
