Measuring accuracy (according to DIN 16 086, DIN V 19 259-1 and IEC 770)
Measuring deviation
Reference conditions acc. to IEC 770, e.g.
- temperature
15°C … 35°C
- rel. humidity 45 % … 75 %
- air pressure 860 mbar … 1060 mbar
Determination of characteristics limit point adjustment acc. to DIN 16 086
Characteristics linear
Deviation in characteristics 1) < 0.25 %
Hysteresis (repeatability) 1) < 0.02 %
1) Relating to the nominal range
2) In compensated temperature range of 0°C … +80°C, reference temperature 20°C
3) According to IEC 770, Punkt 6.3.2 related to the nominal range
4) The use of a properly fitting cable seal in the cable connection is necessary for maintaining the housing
protection IP 66. If the seal used does not fit the cable, it should be replaced by a suitable one.
5) FDA approved
