Smart Differential Pressure Transmitter APR-2000ALW

Availability: In stock
Specification
Metrological parameters

Accuracy:-
  • ≤ ±0,075% of the calibrated range
  • Special version: ≤ ±0,05% of the calibrated range
  • (≤ ±0,04%, ≤ ±0,025% 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 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 Load resistance

Thermal compensation range:-
  • -25…80°C

Zero shift error for static pressure:-
  • 0,01% (FSO) / 150 psi for ranges no. 3, 4, 5, 6, 7, 9
  • 0,03% (FSO) / 150 psi for range no. 8
  • 0,06% (FSO) / 150 psi for ranges no. 1, 2
  • 0,01% (FSO) / 150 psi for ranges no. 2, 8 in HS version
  • 0,02% (FSO) / 150 psi for range no. 10
  • Zeroing the transmitter in conditions of static pressure can elimi- nate this error.

Additional electronic damping:-
  • 0…60 s

Error due to supply voltage changes:-
  • 0,002% (FSO) / V

Description

The APR-2000AL 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 3600/4600/6000/10000 psi. The casing is made of aluminium alloy cast or 316SS stainless 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.

  • 4…20 mA output signal + HART 5 / HART 7 protocol (special version: 0…20 mA or 0…5 mA output signal + HART 5 protocol)
  • Display with backlight
  • Safety version SIL2/SIL3
  • Intrinsic safety certificate ATEX, IECEx, FM (USA, Canada)
  • Explosion proof certificate ATEX, IECEx, FM (USA, Canada)
  • Programmable zero range, shift, characteristic and damping ratio with local panel keys
  • Static pressure limit up to 8700psi
  • Accuracy 0,075% (0,05%, 0,04% on request)
  • Marine certificate – DNV, BV
  • Gold plated diaphragms
  • Wetted parts material 316L/Hastelloy C276
