MPa = bar ÷ 10 / kPa = bar × 100
Analogue measuring range for PN004A = 010 bar
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!
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
Analogue signal 420 mA / 010 V
