• The pressure sensor
detects the system pressure,
• shows the current system pressure on its
display,
• and generates
2 output signals
according to the set output
configuration.
Applications
(Type of pressure: relative pressure)
Avoid static and dynamic overpressure exceeding the given over-
load pressure.
For gaseous media the application is limited to max. 25bar.
Even if the bursting pressure is exceeded only for a short time
the unit can be destroyed (danger of injuries)!
