Measurement ranges and metrological parameters
5.3.1. APR-2000ALW. Measurement ranges
The maximum vertical diaphragm seal spacing shown in the table applies to level measurement,
ensuring that it is possible to set the zero point of the transmitter when the tank is empty.
For measurements of density or phase boundaries (in the sugar and chemical industries and
in refineries) the vertical spacing of the diaphragm seals can be larger.
5.3.3. APR-2000ALW, APR-2200ALW. Permitted environmental conditions
Operating temperature range -25º ÷ 85ºC (for PED version in accordance with p.5.3.5)
Special version -40º ÷ 85ºC
Operating temperature range for intrinsic-safe versions in accordance with Appendix Exi.ATEX
or Appendix Exi.IECEx.
Operating temperature range for flame-proof versions in accordance with Appendix Exd.ATEX
or Appendix Exd.IECEx.
Medium temperature range -25º ÷ 120ºC – for direct measurement,
for PED version in accordance with p. 5.3.6
over 120ºC measurement with a transmission
tube or diaphragm seal using
Thermal compensation range -25º ÷ 80ºC
Relative humidity max 98% with condensation
For transmitters with diaphragm seals permissible temperature and corrosive properties of the medium depend
on the type of separators, see see Catalogue Cards.
