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

Technical data

Accuracy: ±0,1% of calibrated range

Long-term stability: 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

      Optional: SS316

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
