Accuracy ± 0.1% (FSO) for the APR-2200ALW)
The other parameters as given in the p. 5.3.4.
Sealing effect errors – as given in the relevant diaphragm seal Catalogue Card concerning the distance seal.
NOTE: The additional absolute zero error due to ambient temperature can be compensated by configuring
the transmitter, seals and capillaries in accordance with the recommendations on pages II/ 23 and
II/ 24 Product Catalogue.
5.3.6. APR-2000ALW Metrological Parameters according to PED version
APR-2000ALW transmitters which conform to PED are characterised by a measurement range of between -
1bar and 250bar, static pressure of 250bar and the overpressure of PS=275bar.
The permissible operating temperature for option according to:
- H1 Module is between TS min/max: -25ºC and 100ºC;
