Application and construction

The APRE-2000 transmitter is applicable to the measurement of differential pressure of gases, vapors 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 or 320 bar. Electronics in the casing with a degree of protection IP65, IP66.

Technical data

Metrological parameters

Accuracy Ł ±0,1% of calibrated range

Long term stability Ł accuracy for 3 years

(for the nominal measuring range) Ł 2 x accuracy for 5 years

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

0,03% (FSO) / 10 bar for range no. 8

0,06% (FSO) / 10 bar for ranges no. 1, 2

Zeroing the transmitter in conditions of static pressure can eliminate

this error.

Additional electronic damping 0…30 s

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

Electrical parameters

Power supply 7,5...55 VDC (Ex ia 7,5...30 VDC)

Output signal 4...20 mA + HART

Resistance required for communication min. 240 W

Materials

Wetted parts SS316L

Diaphragms SS316L

Casing SS304

Operating conditions

Operating temperature range (ambient temp.) -25...85°C

Exi a version -25…80°C

Medium temperature range -25...120°C

PED version -25...100°C

over 120°C – measurement with use an impulse line or diaphragm seals up to 100°C – version for 413bar static pressure

CAUTION: the medium must not be allowed to freeze in the impulse line or close to the process connection of the transmitter
