Ground connected
Lower range value = 0 bar
Calibration position: Diaphragm seal on same height
Reference accuracy: See data sheet
Long-term drift: Refer to nominal range ≤ 0.1 % within 5 years
Temperature influence of ambient temperature: See data sheet
Temperature influence output (-40...80 °C): ≤ ±(0.04 % / 10 K)
Influence static pressure (per EN 61298-3): Refer to nominal range: ≤ ±(0.1 % + 0.1 % x TD)
