U - variant
(Range: 0...+ xx Pa)
After successful zero point calibration, the output voltage
is 0 V at 0 Pa pressure difference (with the offset knob
in central position)!
Output voltage 0...10 V
for pressure difference from 0 Pa to final value
U - variant
(Range: – xx ... + xx Pa)
After successful zero point calibration, the output voltage
is 5 V at 0 Pa pressure difference (with the offset knob in
central position)!
Output voltage 0...10 V
for pressure difference – ΔP ... +ΔP
I - variant
(Range: 0...+ xx Pa)
After successful zero point calibration, the output current
is 4 mA at 0 Pa pressure difference (with the offset knob
in central position)!
Output current 4...20 mA
for pressure difference from 0 Pa to final value
I - variant
(Range: – xx ... + xx Pa)
After successful zero point calibration, the output current
is 12 mA at 0 Pa pressure difference (with the offset knob
in central position)!
Output current 4... 20 mA
for pressure difference – ΔP ... +ΔP
