APR-2000ALW -Smart Differential Pressure Transmitter

Smart Differential Pressure Transmitter APR-2000ALW

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.

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

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.

Thermal compensation range:-

-25…80°C

Additional electronic damping:-

0…60 s

Error due to supply voltage changes:-

0,002% (FSO) / V
