Applications (type of pressure: relative pressure)
Avoid static and dynamic overpressure exceeding the given over-
load pressure.
Even if the bursting pressure is exceeded only for a short time
the unit can be destroyed (danger of injuries)!
For gaseous media the application is limited to max. 25 bar.
Before mounting and removing the sensor, make sure that no
pressure is applied to the system.
Mount the pressure sensor on a G¼ process connection.
