CẢM BIẾN ÁP SUẤT DẠNG CHÊNH ÁP APLISENS MODEL PRE-28 SMART

Technical data

Accuracy Ł ±0,1% of calibrated range

Long-term stability Ł accuracy for 3 years

(for the basic range)

Thermal error < ±0,08% (FSO) / 10°C

max. ±0,3% (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

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, Au

Casing: SS304

Operating conditions

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

Exia version -25…80°C

Medium temperature range -25...120°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
