Aplisens APRE-2000 ALW Smart Differential Pressure Transmitter

Aplisens APRE-2000 ALW Smart Differential Pressure Transmitter

Aplisens APRE-2000 ALW Smart Differential Pressure 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.

Aplisens APRE-2000 ALW 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.
  • Response time:
    • 16…480ms (programmable)
    • Exd version: 150ms
  • Additional electronic damping: 0…60 s
  • Error due to supply voltage changes: 0,002% (FSO) / V
