Specification

Accuracy	≤ ±0.1% of the calibrated range
Long-term stability (for the nominal measuring range)	≤ accuracy for 3 years
Thermal error	< ±0,08% (FSO) / 10°C
Thermal error	max. ±0.3% (FSO) in the whole compensation range
Thermal compensation range	-25…80°C
Zero shift error for static pressure	0,01% (FSO) / 10 bar for ranges no. 3, 4, 5, 6, 7, 9
