MPa = bar ÷ 10 / kPa = bar × 100
Avoid static and dynamic overpressure exceeding the given overload
pressure by taking appropriate measures�
The indicated bursting pressure must not be exceeded�
Even if the bursting pressure is exceeded only for a short time, the unit
may be destroyed� NOTE: Risk of injury!
Use in gases at pressures > 363 PSI (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 the damping device can become unus-
able�
If you have any questions, please contact ifm electronic’s sales specialists�
4 Function
4.1 Processing of the measured signals
• The unit displays the current system pressure�
• It generates 2 output signals according to the parameter setting�
OUT1
• Switching signal for system pressure limit value�
OUT2
2 options
• Switching signal for system pressure limit value�
• Diagnostic signal (output 2 is inactive in case of a fault)�
