Aplisens Smart differential pressure transmitter APRE-2000 ALW

The APR-2000ALW transmitter is applicable to the measurement of differential pressure of gases, vapours and liquids. The active element is a piezoresistant silicon sensor separated from the medium by separating diaphragms and a specially selected type of manometric fluid. The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/413/700 bar. The casing is made of aluminium alloy cast or 316SS stainles steel, degree of protection IP66/IP67. The design of the casing enables the use of a local display, rotation of the display, rotation of the casing by 0–340° relative to the sensor, and a choice of cable direction.

Technical Data

Metrological Parameters

• Accuracy:
  • ≤ ±0,075% of the calibrated range
  • (≤ ±0,1% for range no. 10)
  • Special version: ≤ ±0,05% of the calibrated range
  • (≤ ±0,04% on request)
• Long term stability (for the nominal measuring range):
  • ≤ accuracy for 3 years
  • or ≤ 2 x accuracy for 5 years
  • HS version: ≤ accuracy for 6 years
  • or ≤ 2 x accuracy for 10 years
• Thermal error:
  • < ±0,05% (FSO) / 10°C for ranges no. 1 - 9
  • < ±0,08% (FSO) / 10°C for ranges no. 10
  • max. ±0,25% (FSO) in the whole compensation range
  • spec. version for ranges no 1-9:
    • ≤ ±0,03% (FSO) / 10°C
    • max. ±0,1% (FSO) in the whole compensation range
• Thermal compensation range: -25…80°C
• Zero shift error for static pressure:
  • 0,01% (FSO) / 10 bar for ranges no. 3, 4, 5, 6, 7, 9
  • 0,03% (FSO) / 10 bar for range no. 8
  • 0,06% (FSO) / 10 bar for ranges no. 1, 2
  • 0,01% (FSO) / 10 bar for ranges no. 2, 8 in HS version
  • 0,02% (FSO) / 10 bar for range no. 10
    Zeroing the transmitter in conditions of static pressure can eliminate this error.
