Reference conditions and actuating variables (according to DIN EN 60770-1)
Reference conditions according to DIN EN 61298-1
Ʋ Temperature 18 … 30 °C (64 … 86 °F)
Ʋ Relative humidity 45 … 75 %
Ʋ Air pressure 860 … 1060 mbar/86 … 106 kPa (12.5 … 15.4 psi)
Determination of characteristics limit point adjustment according to DIN 16086
Characterstic curve Linear
Reference installation position upright, diaphragm points downward
Influence of the installation position < 5 mbar/0.5 kPa (0.07 psig)
Deviation determined according to the limit point method according to IEC 60770 10)
Applies to the digital signal output (HART, Profibus PA, Foundation Fieldbus) as well as to ana-
logue current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal
measuring range/set span.

Ʋ Turn down 1 : 1 up to 5 : 1 < 0.075 %
Ʋ Turn down > 5 : 1 < 0.015 % x TD
Deviation with version 0.1 %
Ʋ Turn down 1 : 1 up to 5 : 1 < 0.1 %
Ʋ Turn down > 5 : 1 < 0.02 % x TD
Deviation with version 0.2 %
Ʋ Turn down 1 : 1 up to 5 : 1 < 0.2 %
Ʋ Turn down > 5 : 1 < 0.04 % x TD
Deviation with absolute pressure measuring range 0.1 bar
Ʋ Turn down 1 : 1 up to 5 : 1 < 0.25 %
Ʋ Turn down > 5 : 1 < 0.05 % x TD
Influence of the product or ambient temperature
Average temperature coefficient of the zero signal
Applies to digital interfaces (HART, Profibus PA, Foundation Fieldbus) as well as to analogue
current output 4 … 20 mA and refers to the set span. Turn down (TD) is the ratio nominal measuring
range/set span.
