1 Safety instructions
Please read the product description prior to installing the unit.
Ensure that the product is suitable for your application without any restrictions.
If the operating instructions or the technical data are not adhered to, personal
injury and/or damage to property may occur.
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!
2 Function and features
The pressure sensor detects the system pressure and converts it into an analog
output signal.
4 ... 20 mA

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.
