Reference conditions and actuating variables (similar to DIN EN 60770-1)

Reference conditions according to DIN EN 61298-1

- Temperature +18 … +30 °C (+64 … +86 °F)

- Relative humidity 45 … 75 %

- Air pressure 860 … 1060 mbar/86 … 106 kPa (12.5 … 15.4 psig)

Determination of characteristics Limit point adjustment according to IEC 61298-2

Characteristics linear

Reference installation position upright, diaphragm points downward

Inﬂuence of the installation position depending on the isolating diaphragm version

Deviation determined according to the limit point method according to IEC 60770

11)

Applies to digital interfaces (HART, Proﬁbus PA, Foundation Fieldbus) as well as to analogue

current output 4 … 20 mA . Speciﬁcations refer to the set span. Turn down (TD) is the ratio nominal

measuring range/set span.

Deviation for measuring ranges 0.4 … 1000 bar

- Turn down 1 : 1 up to 5 : 1 < 0.1 %

- Turn down > 5 : 1 < 0.02 % x TD

Deviation for measuring ranges > 1000 bar

- Turn down 1 : 1 up to 2 : 1 < 0.6 %

Deviation with absolute pressure measuring range 0.1 bar

- Turn down 1 : 1 up to 5 : 1 < 0.25 %

- Turn down > 5 : 1 < 0.05 % x TD

11)

Incl. non-linearity, hysteresis and non-repeatability.
