Case 3:
•4 to 20 mA
Example 3:
• Sensor measuring range: 0 to 10 bar
• Extended measuring range: –0.5 to 10.5 bar
• A pressure of 0.5 bar is applied at the device. The zero
point can be adjusted in the range –0.5 to 1.5 bar.
Example 4:
• Sensor measuring range: 0 to 10 bar
• Extended measuring range: -0.5 to 10.5 bar
• A pressure of 1 bar is applied at the device. The zero point
can be adjusted in the range 0 to 2 bar.
