SITRANS P measuring instruments for pressure
Transmitters for gage, absolute and differential pressure
ZD series for gage and absolute pressure
• Upper and lower current saturation limit
• Electrical damping
The other two keys are used to set the values in the individual op-
erating modes.

Two LED indicators are fitted above the display to monitor the set
range and the status.
The green LED signals that the measured pressure lies within the
set limits. The red LED lights up when the measured pressure
lies outside the set limits and when there is an error.
