Cảm biến đo chênh áp Kaifeng Instrument KFB-3151DP
Measurement range ratio: 10: 1
Basic error: Measurement range is 3, 4, 5
When the measurement range ratio is 1:1 to 10:1, it is ±0.5% of the adjustment measurement range
When the measurement range ratio is 10:1 to 40:1, it is ±0.25 (1+0.1URL/measurement range) % of the measurement range
Stability: ±0.15%/6 month of the max measurement range.
Influence from temperature: zero point temperature error is ±0.32/20℃ of max measurement range
Note: The influence from temperature error is doubled to measurement range 3 and 9
Influence from static pressure: (DP type at linear output) zero point error: add static pressure 10MPa, zero point error is ±0.25% of the max measurement range, this is the system error, the transmitter zero point shall be adjusted according to the actual static pressure before installing to eliminate this error. (HP type at linear output) zero point error: add static pressure 31.2MPa, zero point error < ±2.0% of max measurement range. This is the system error, the transmitter zero point shall be adjusted according to the actual static pressure before installing to eliminate this error.
Overpressure limit: DP、GP、AP: ≤10MPa
HP: ＜32MPa
Damping: Time constant is adjustable ranging 0.2- 32.0s.
Startup time: 3s, warm-up is not needed.
